Secure Data Sharing In an Untrusted CloudIJERA Editor
Cloud computing is a huge area which basically provides many services on the basis of pay as you go. One of the fundamental services provided by cloud is data storage. Cloud provides cost efficiency and an efficient solution for sharing resource among cloud users. A secure and efficient data sharing scheme for groups in cloud is not an easy task. On one hand customers are not ready to share their identity but on other hand want to enjoy the cost efficiency provided by the cloud. It needs to provide identity privacy, multiple owner and dynamic data sharing without getting effected by the number of cloud users revoked. In this paper, any member of a group can completely enjoy the data storing and sharing services by the cloud. A secure data sharing scheme for dynamic cloud users is proposed in this paper. For which it uses group signature and dynamic broadcast encryption techniques such that any user in a group can share the information in a secured manner. Additionally the permission option is proposed for the security reasons. This means the file access permissions are generated by the admin and given to the user using Role Based Access Control (RBA) algorithm. The file access permissions are read, write and delete. In this, owner can provide files with options and accepts the users using that option. The revocation of cloud user is a function generated by the Admin for security purpose. The encryption computational cost and storage overhead is not dependent on the number of users revoked. We analyze the security by proofs and produce the cloud efficiency report using cloudsim.
Secure Redundant Data Avoidance over Multi-Cloud Architecture. IJCERT JOURNAL
Redundant data avoidance systems, the Private Cloud are involved as a proxy to allow data owner/users to securely perform duplicate check with differential privileges. Such architecture is practical and has attracted much attention from researchers. The data owners only outsource their data storage by utilizing public cloud while the data operation is managed in private cloud, in this connection our presented system has follows traditional encryption while providing data confidentiality, is incompatible with redundant data avoidance. Identical data copies of different users will lead to different ciphertexts, making data avoidance impossible. To address above issues convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, this paper makes the first attempt to formally address the problem of authorized redundant data avoidance. Different from traditional redundant data avoidance systems, the differential privileges of users are further considered in duplicate check besides the data itself. We also present several new redundant data avoidance constructions supporting authorized duplicate check in a multi-cloud architecture. Security analysis demonstrates that our scheme is secure in terms of the definitions specified in the proposed security model. In order to perform secure access controlling scheme user may satisfy fine-grained approach at cloud level towards access restricting from unauthorized users or adversaries.

Design and implementation of a privacy preserved off premises cloud storagesarfraznawaz
Despite several cost-effective and flexible characteristics of cloud computing, some clients are reluctant to adopt this paradigm due to emerging security and privacy concerns. Organization such as Healthcare and Payment Card Industry where confidentiality of information is a vital act, are not assertive to trust the security techniques and privacy policies offered by cloud service providers. Malicious attackers have violated the cloud storages to steal, view, manipulate and tamper client's data. Attacks on cloud storages are extremely challenging to detect and mitigate. In order to formulate privacy preserved cloud storage, in this research paper, we propose an improved technique that consists of five contributions such as Resilient role-based access control mechanism, Partial homomorphic cryptography, metadata generation and sound steganography, Efficient third-party auditing service, Data backup and recovery process. We implemented these components using Java Enterprise Edition with Glassfish Server. Finally we evaluated our proposed technique by penetration testing and the results showed that client’s data is intact and protected from malicious attackers.
Improving Efficiency of Security in Multi-CloudIJTET Journal
Abstract--Due to risk in service availability failure and the possibilities of malicious insiders in the single cloud, a movement towards “Multi-clouds” has emerged recently. In general a multi-cloud security system there is a possibility for third party to access the user files. Ensuring security in this stage has become tedious since, most of the activities are done in network. In this paper, an enhanced security methodology has been introduced in order to make the data stored in cloud more secure. Duple authentication process introduced in this concept defends malicious insiders and shields the private data. Various disadvantages in traditional systems like unauthorized access, hacking have been overcome in this proposed system and a comparison made with the traditional systems in terms of performance and computational time have shown better results.
Privacy Preserving in Cloud Using Distinctive Elliptic Curve Cryptosystem (DECC)ElavarasaN GanesaN
Securing the data over a cloud network is always a challenging problem

A PRACTICAL CLIENT APPLICATION BASED ON ATTRIBUTE-BASED ACCESS CONTROL FOR UN...cscpconf
One of widely used cryptographic primitives for the cloud application is Attribute Based Encryption (ABE) where users can have their own attributes and a ciphertext encrypted by an access policy. Though ABE provides many benefits, the novelty often only exists in an academic world and it is often difficult to find a practical use of ABE for a real application. In this paper, we discuss the design and implementation of a cloud storage client application which supports the concept of ABE. Our proposed client provides an effective access control mechanism where it allows different types of access policy to be defined thus allowing large datasets to be shared by multiple users. Using different access policy, each user only needs to access only a small part of the big data. The goal of our experiment is to explore the right set of strategies for developing a practical ABE-based system. Through the implementation and evaluation, we have determined the various characteristics and issues associated with developing a practical ABEbased
application.
Bio-Cryptography Based Secured Data Replication Management in Cloud StorageIJERA Editor
Cloud computing is new way of economical and efficient storage. The single data mart storage system is a less
secure because data remain under a single data mart. This can lead to data loss due to different causes like
hacking, server failure etc. If an attacker chooses to attack a specific client, then he can aim at a fixed cloud
provider, try to have access to the client’s information. This makes an easy job of the attackers, both inside and
outside attackers get the benefit of using data mining to a great extent. Inside attackers refer to malicious
employees at a cloud provider. Thus single data mart storage architecture is the biggest security threat
concerning data mining on cloud, so in this paper present the secure replication approach that encrypt based on
biocrypt and replicate the data in distributed data mart storage system. This approach involves the encryption,
replication and storage of data
Messages addressed to specific users can be decrypted by Key Generation Centre (KGC) by generating their private keys. Data owner wants the data to be delivered only to specified user and not to unauthorized person that is the data owner makes their private data accessible only to authorized person. We propose attribute based encryption and escrow problem which means written agreement delivered to a third party to overcome this problem. Attribute based Encryption (ABE) is a type of public-key encryption in which the private key of a user and the cipher text are dependent upon attributes. It is a promising cryptographic approach.

Enhanced Data Partitioning Technique for Improving Cloud Data Storage SecurityEditor IJMTER
Cloud computing is a model for enabling for on demand network access to shared
configurable computing resources (e.g. networks, servers, storage, applications, and services).It is
based on virtualization and distributed computing technologies. Cloud Data storage systems enable
user to store data efficiently on server without any trouble of data resources. User can easily store
and retrieve their data remotely. The two biggest concerns about cloud data storage are reliability and
security. Clients aren’t like to entrust their data to another third party or companies without a
guarantee that they will be able to access therein formations whenever they want. In the existing
system, the data are stored in the cloud using dynamic data operation with computation which makes
the user need to make a copy for further updating and verification of the data loss. Different
distributed storing auditing techniques are used for overcoming the problem of data loss. Recent
work of this paper has show that data partitioning technique used for data storage by providing
Digital signature to every partitioning data and user .this technique allow user to upload or retrieve
the data with matching the digital signatures provided to them. This method ensures high cloud
storage integrity, enhanced error localization and easy identification of misbehaving server and
unauthorized access to the cloud server. Hence this work aims to store the data securely in reduced
space with less time and computational cost.

Effective & Flexible Cryptography Based Scheme for Ensuring User`s Data Secur...ijsrd.com
Cloud computing has been envisioned as the next-generation architecture of IT enterprise. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique attribute, however, poses many new security challenges which have not been well understood. In this article, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible cryptography based scheme. Extensive security and performance analysis shows that the proposed scheme is highly efficient and resilient against malicious data modification attack.

A Secure Multi-Owner Data Sharing Scheme for Dynamic Group in Public Cloud. IJCERT JOURNAL
In cloud computing outsourcing group resource among cloud users is a major challenge, so cloud computing provides a low-cost and well-organized solution. Due to frequent change of membership, sharing data in a multi-owner manner to an untrusted cloud is still its challenging issue. In this paper we proposed a secure multi-owner data sharing scheme for dynamic group in public cloud. By providing AES encryption with convergent key while uploading the data, any cloud user can securely share data with others. Meanwhile, the storage overhead and encryption computation cost of the scheme are independent with the number of revoked users. In addition, I analyze the security of this scheme with rigorous proofs. One-Time Password is one of the easiest and most popular forms of authentication that can be used for securing access to accounts. One-Time Passwords are often referred to as secure and stronger forms of authentication in multi-owner manner. Extensive security and performance analysis shows that our proposed scheme is highly efficient and satisfies the security requirements for public cloud based secure group sharing.
Dynamic Resource Allocation and Data Security for CloudAM Publications
Cloud computing is the next generation of IT organization. Cloud computing moves the software and
databases to the large centres where the management of services and data may not be fully trusted. In this system, we
focus on cloud data storage security, which has been an important aspect of quality of services. To ensure the
correctness of user’s data in the cloud, we propose an effective scheme with Advanced Encryption Standard and MD5
algorithm. Extensive security and performance analysis shows that the proposed scheme is highly efficient. In
proposed work we have developed efficient parallel data processing in clouds and present our research project for
parallel security. Parallel security is the data processing framework to explicitly exploit the dynamic storage along with
data security. We have proposed a strong, formal model for data security on cloud and corruption detection.
A Survey on Different Techniques Used in Decentralized Cloud ComputingEditor IJCATR
This paper proposes various methods for anonymous authentication for data stored in cloud. Cloud verifies the authenticity
of the series without knowing the user’s identity before storing data. This paper also has the added feature of access control in which
only valid users are able to decrypt the stored information. These schemes also prevents replay attacks and supports creation,
modification, and reading data stored in the cloud. Moreover, our authentication and access control scheme is decentralized and robust,
unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage
overheads are comparable to centralized approaches .The aim of this paper is to cover many security issues arises in cloud computing
and different schemes to prevent security risks in cloud. Storage-as-a-service (Saas) offered by cloud service providers (CSPs) is a paid
facility that enables organizations to outsource their sensitive data to be stored on remote servers. In this paper, we propose a cloudbased
storage schemes that allows the data owner to benefit from the facilities offered by the CSP and enables indirect mutual trust
between them. This Paper provides different authentication techniques and algorithms for cloud security.
Cloud Computing is the revolution in current generation IT enterprise. Cloud computing displaces database and application software to the large data centres, where the management of services and data may not be predictable, where as the conventional solutions, for IT services are under proper logical, physical and personal controls. This aspect attribute, however comprises different security challenges which have not been well understood. It concentrates on cloud data storage security which has always been an important aspect of quality of service (QOS). In this paper, we designed and simulated an adaptable and efficient scheme to guarantee the correctness of user data stored in the cloud and also with some prominent features. Homomorphic token is used for distributed verification of erasure – coded data. By using this scheme, we can identify misbehaving servers. In spite of past works, our scheme supports effective and secure dynamic operations on data blocks such as data insertion, deletion and modification. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centres, where the data management and services may not be absolutely truthful. This effective security and performance analysis describes that the proposed scheme is extremely flexible against malicious data modification, convoluted failures and server clouding attacks.

In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centres, where the data management and services may not be absolutely truthful. This effective security and performance analysis describes that the proposed scheme is extremely flexible against malicious data modification, convoluted failures and server clouding attacks.
Security Check in Cloud Computing through Third Party Auditorijsrd.com
In cloud computing, data owners crowd their data on cloud servers and users (data consumers) can access the data from cloud servers. Due to the data outsourcing, however, it requires an independent auditing service to check the data integrity in the cloud. Some existing remote integrity checking method scan only serve for static records data. Thus, cannot be used in the auditing service since the data in the cloud can be animatedly updated. Thus, an efficient and secure dynamic auditing protocol is required to convince data owners that the data are correctly stored in the cloud. In this paper, we first design an auditing framework for cloud storage systems for privacy-preserving auditing protocol. Then, we extend our auditing protocol to support the data dynamic operations, which is efficient to secure the random model.

Abstract: The cloud storage administration has turned into a speedier benefit development by giving its
components to customer's information. Security protection and information respectability are the two principle
issues confronted by single cloud administration suppliers. Henceforth dispersed cloud environment, multi cloud is
utilized. In the current framework, when customer stores his information on multi-cloud servers, the disseminated
storing and respectability checking are at danger. Provable information ownership is a technique for guaranteeing
the respectability of information away outsourcing. The proposed ID-DPDP convention ready to furnish customer's
character with his private key and provably secure under the hardness presumption of the standard CDH issue.. It
will check customers information kept securely without downloading the entire information. This convention kills
testament administration, productive and adaptable. The earth of cloud computing has formed into a fundamental
subject in a considerable amount of ranges. The conveyed storing and additionally honesty checking is essential for
a typical circumstance, when customer develop his data on the servers of multi-cloud. Strategy of trustworthiness
checking must be pragmatic to make it suitable in backing of limit constrained end gadgets along these lines, in view
of disseminated calculation, we will learn circulated model of remote information honesty checking and set forward
the comparing solid technique in multi-cloud storage. Thus in our work we start novel affirmation model of remote
information honesty known character based circulated provable information ownership inside multi-cloud storage.
On the premise of customer's approval, proposed strategy can comprehend private check, assigned confirmation
and additionally open check. The anticipated strategy is provably clever and ensured. Other than auxiliary point of
interest of end of endorsement administration, character based convention of conveyed provable information
ownership is also capable and adaptable. To improve the adequacy, personality based provable information
ownership is all the more striking and consequently, more supportive to ponder.
Keywords: Multi-cloud storage, Cooperative Provable Data Possession, Hash Index Hierarchy.
I. Introduction
With the appearance of new advancements like Web Services and Virtualization, cloud computing turned
into a reality. With cloud computing individuals can get three sorts of administrations, for example, stage as an
administration, programming as an administration and foundation as an administration. The cloud organization
models incorporate private cloud, open cloud, group cloud and half and half cloud. The private cloud is the cloud
inside an association's system. Open cloud is the cloud available to whole world through web in light of specific
guidelines. The group cloud is among organizations secretly while the crossover cloud is the blend of two or more
sorts of cloud. As the cloud is turning out to be more famous, there are developing security concerns. These security
concerns prompted the examination in the zone and numerous scientists proposed conventions and systems to
guarantee cloud information security. The cloud administration suppliers deal with contend security of cloud
information. Be that as it may, as the cloud is in trusted (got to through Internet), parcel of examination went on
capacity security in cloud. A portion of the papers and their procedures are quickly given here. In [1] conveyed
confirmation conventions are developed for guaranteeing information storing security in cloud computing. This is
accomplished by executing a conveyed examining component which guarantees that the information progression of
all cloud clients are guaranteed and tried for uprightness. In [2] an outsider examining instrument is actualized with
a specific end goal to secure cloud storage. Nonstop accuracy of information is the SLA (Service Level Agreement)
executed in this paper. Open reviewing of this paper helps in information uprightness of different cloud clients. In
[3] another methodology is displayed. It is known as appropriated responsibility for information sharing. It is
accomplished by actualizing a JAR which has information and security component other than availability records for
different cloud clients. In [4] multi mists are actualized to protect information of customers. At the end of the day it
is the billow of mists for enhancing power of capacity security. In [5] a novel methodology is utilized to store,
2. Personality Based Dispersed Provable Information Ownership In Multi Distributed Storage
DOI: 10.9790/0661-1803035056 www.iosrjournals.org 51 | Page
recover and forward information in the cloud. It utilizes secure deletion code to guarantee information security and
encryption instruments for sending information to other honest to goodness clients. In [6] helpful provable
information ownership idea is utilized. It guarantees that cloud environment works helpfully and secure information.
In [7] security to cloud information is given utilizing Sobol Sequence. This paper executed a dispersed confirmation
convention that transfers on deletion code. In [8] likewise open inspecting is actualized for cloud storage security.
The outsider examiner checks for information trustworthiness and guarantees that the information is not messed
around with in the server. Whatever is left of this paper is dedicated to survey three papers relating to information
storing security issues in cloud. All papers accepted that, the cloud storage is not secure as the administration
supplier may erase information or the cloud proprietor does not unveil capacity issues in the cloud. In this manner,
on the premise of disseminated calculation, we will learn appropriated checking of remote information uprightness
show and give relating solid convention in multi-cloud storage. Out in the open key foundation, convention of
provable information ownership requires open key declaration dispersion and overseeing and it will bring about
significant overheads as the verifier will ensure the testament when it checks remote information respectability. In
cloud computing, generally of verifiers just contain low calculation capacity. Character based open key
cryptography can dispose of complex testament administration. To improve adequacy, character based provable
information ownership is all the more striking subsequently, it will be critical to learn personality based
disseminated provable information ownership [3][4]. The anticipated personality based convention of dispersed
provable information ownership is provably secured in hardness supposition of standard computational Diffie-
Hellman trouble. Also to auxiliary advantage of disposal of authentication administration, our character based
disseminated provable information ownership is in addition capable and adaptable.
II. Related Work
Security in cloud is essential. To check the accessibility and respectability of outsourced information in
cloud stockpiles, specialists have recommended two essential methodologies called Provable Data Possession (PDP)
[2] and Proofs of Retrievability (POR) [3]. Ateniese et al. [2] initially proposed the PDP model for guaranteeing
ownership of records on untrusted MeghaPatil et al,/(IJCSIT) International Journal of Computer Science and
Information Technologies, Vol. 5 (2) , 2014, 982-985 www.ijcsit.com 982 stockpiles without recovering it.
Customer keeps up steady measure of metadata to check evidence. This PDP approach has likewise given a RSA-
based plan to a static case that accomplishes the ܱ (1) correspondence cost. They additionally proposed a freely
unquestionable rendition, which permits customer (information proprietor) and also anybody other than proprietor,
to challenge the server for information ownership. This property has had gigantic effect on application territories of
PDP convention because of the partition of information proprietors and the clients. Be that as it may, these
procedures are unstable against replay assaults in element situations. In addition, they don't fit for multi-cloud
storage because of the loss of homomorphism property in the confirmation procedure. Ateniese et al. built up an
element PDP arrangement called Scalable PDP [4]. This very effective and provably secure PDP procedure is
construct totally in light of symmetric key cryptography without requiring any mass encryption. This PDP method
permits outsourcing of element information, i.e. it bolsters operations, for example, erasure, piece change and affix,
However, since it is based upon symmetric key cryptography, it is inadmissible for open (outsider) confirmation.
Likewise, servers can cheat the proprietors by utilizing past metadata or reactions because of the absence of
irregularity in the difficulties. The quantities of difficulties and redesigns are constrained and settled ahead of time
and clients can't perform piece insertions anyplace. In view of past work, Erway et al. [5] proposed two Dynamic
PDP plans with a hash capacity tree to acknowledge (log ܱ ) correspondence and computational expenses for a ܱ -
square record. The fundamental plan, called DPDP-I, keeps the downside of Scalable PDP, and in the "blockless"
plan, called DPDPII, the information squares can be spilled by the reaction of a test, .However, these plans are
likewise not powerful for a multicloud domain in light of the fact that the check way of the test piece can't be put
away totally in a cloud [8]. Juels and Kaliski [3] introduced a POR plan, which depends generally on preprocessing
steps that the customer conducts before sending a document to a CSP. Shockingly, these activities keep any effective
augmentation for redesigning information. Shacham and Waters [6] presented an enhanced variant of this
convention called Compact POR. This convention utilizes homomorphic property to total a proof into (1)
authenticator esteem and ()ݐ calculation cost for ݐ challenge squares, however their answer couldn't keep the
spillage of information pieces in the check procedure as a result of its static nature. Wang et al. [7] gave a dynamic
plan (log ܱ ) cost by coordinating the Compact POR plan and Merkle Hash Tree (MHT) into the DPDP. A few POR
plans and models have been as of late proposed including [9], [10]. In [9] Bowers et al. presented a dispersed
cryptographic framework that permits an arrangement of servers to take care of the PDP issue. This structure
depends on an uprightness ensured blunder redressing code (IP-ECC), which redesigns the security and productivity
3. Personality Based Dispersed Provable Information Ownership In Multi Distributed Storage
DOI: 10.9790/0661-1803035056 www.iosrjournals.org 52 | Page
of existing instruments. Notwithstanding, a record must be changed into particular sections with the same length,
which are disseminated crosswise over servers.
III. Demonstrating Of Identity-Based Protocol Of Cloud Provable Data Possession
Cloud computing has end up being an essential subject in a few ranges. It takes data handling as an
administration, and calms trouble for overseeing of capacity, all inclusive information access with self-governing
geological areas. The issue to persuade cloud customers that their information is undamaged is specifically vital on
the grounds that the customer's don't collect these information locally [3][4]. Checking of disengaged information
uprightness is a primitive to handle this issue. For general circumstance, when customer amass his data on the
servers of multicloud, the dispersed storing and honesty checking are crucial. Convention of respectability checking
must be ingenious keeping in mind the end goal to make it suitable for limit constrained end gadgets therefore, in
light of disseminated calculation, we will learn circulated model of remote information uprightness checking and set
forward the relating solid system in multi-cloud storage. In personality based open key cryptography, our work
concentrates on dispersed provable information ownership inside multi-cloud storage which can be made clever by
wiping out declaration administration. The convention of solid character premise circulated provable information
ownership development for the most part originates from signature, provable information ownership and in addition
appropriated figuring. Information honesty checking representation is more adaptable other than high adequacy. In
view of customer's approval, proposed ID-DPDP strategy can comprehend private confirmation, designated check
and additionally open check. A personality based convention of appropriated provable information ownership
includes four substances which are appeared in fig1. They are Client: a substance, which has colossal information to
be put away on multi-cloud setting for safeguarding and calculation, can be additionally singular buyer or else
enterprise. Combiner: an element, which gets capacity request and assigns square label sets to equal cloud servers
[5]. At the point when accepting test, it parts test and issues them to a few cloud servers. Amid the getting of
reactions from cloud servers, it consolidates them and forward joined reaction to verifier. Cloud Server: an element,
which is administered by cloud administration supplier, has imperative storage room and calculation asset to
maintain the customers' data. Private Key Generator: a substance, while getting character, it yields comparable
private key.
IV. Cloud Types
Public cloud
A large organization owns the cloud infrastructure and sells cloud services to industries or public. Public
cloud applications, storage, and other resources are made available to the general public by a service provider. These
services are free or offered on a pay-per-use model.
Community cloud
Several organizations that have similar polices, objectives, aims and concerns share the cloud
infrastructure. The common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a
third-party and hosted internally or externally.
Hybrid cloud
Hybrid cloudis a composition of two or more clouds (private, community or public) that remain unique
entities but are bound together, offering the benefits of multiple deployment models. It enables data and application
Probability
Private cloud
The cloud infrastructure is owned or leased by a single organization and is operated solely for that
organization Private cloud is cloud infrastructure operated solely for a single organization, whether managed
internally or by a third-party and hosted internally or externally.
V. Cloud Architecture
It is a systems architecture involved in the delivery of cloud computing, involves multiple cloud
components communicating with each other over a loose coupling mechanism such as a messaging queue. Elastic
provision implies intelligence in the use of tight or loose coupling as applied to mechanisms such as these and
others. It have four basic steps,
1. Cloud infrastructure (eg. Billing VM)

2. Cloud service (eg. Queue)
3. Cloud platform (eg. Web Frontend)
4. Cloud storage (eg. Database)
Fig 1. Cloud Architecture
DISTRIBUTED SERVERS:
The servers are not housed in the same location. Often, they are in geographically disparate location. But
for cloud subscribers, it act as right next to each other. It gives service provider more flexibility in option and
security. If any failure occurred at one site the service be still accessed from another site. If cloud need more
hardware they need not throw more server in the safe room they simply add them at another site as a part of cloud.
Fig 2. Distributed Servers
CLOUD ENTITIES:
End User - End Users need to access certain resources in the cloud and should be aware of access agreements such
asacceptable use or conflict of interest and concerns transmission integrity.
System Architect -System architects are employed with writing the policies that pertain to the installation and
configuration of hardware components such as firewalls, servers, routers, and software.
Developers -Developers build an application in the cloud need to access the infrastructure where the development
environment is located and improve development through elasticity of resources.
Third Party Auditors (TPA) -Third party auditors are used by clients and providers alike to determine the security
of the cloud implementation. Depending on the level of commitment to security and usefulness a cloud vendor may
choose to submit itself to regular security assessments in an attempt to obtain accreditation. The accreditation
process needs to be undertaken every three years.
CLOUD COMPUTING SECURITY:
There are many security issues in cloud and they are classify into main issues,
1. Security issues faced by cloud providers
2 .Security issues faced by their customers
Basic Principles in Information Security:
5. Personality Based Dispersed Provable Information Ownership In Multi Distributed Storage
DOI: 10.9790/0661-1803035056 www.iosrjournals.org 54 | Page
Confidentiality –It is used to prevent disclosure of information to unauthorized person. It is necessary for
maintaining the privacy of personal information.
Integrity – The data should not get modified without knowingly. The data should remain intact unless it is modified
by authorized person.
Availability – The information must be available whenever it is needed. Ensure availability should always prevent
DoS attacks.
VI. Proposed Model
An identity-based protocol of distributed provable data possession procedure is a collection of three
algorithms such as Setup, Extract, TagGen in addition to an interactive proof system known as Proof. Setup
algorithm will Input the security parameter, and it outputs system public parameters such as the master public key
and master secret key. Extract algorithm Inputs public parameters and master public key, master secret key, as well
as identity of a client, it outputs private key that corresponds to client with identity. TagGen algorithm will Input
private key, block and a set of cloud servers it outputs the tuple. Proof is a procedure among Proof, Verifier and
combiner. We put forward the corresponding concrete procedure in multi-cloud storage. The concrete identity-based
protocol of distributed provable data possession construction mostly comes from signature, provable data possession
as well as distributed computing. The signature relates client’s identity by means of his private key. Distributed
computing is generally utilized to accumulate client’s data above multiple cloud servers. This computing is
moreover employed to combine multi-cloud servers’ responses to act in response to verifier’s challenge. This
procedure comprises Setup, Extract, TagGen, as well as Proof. In Extract, Private Key Generator creates private key
in support of client which creates block-tag pair and uploads it towards combiner. Combiner distributes block-tag
pairs towards various cloud servers consistent with storage metadata. Later verifier sends challenge towards
combiner and combiner allocates challenge query to equivalent cloud servers consistent with storage metadata [6].
The cloud server’s act in response to challenge and combiner collect these responses from cloud servers. The
combiner sends combined response to verifier. Finally the verifier ensures whether aggregated response is
applicable.

VII. Aes Algorithm
AES is a block cipher with a block length of 128 bits. • AES allows for three different key lengths: 128,
192, or 256 bits. Most of our discussion will assume that the key length is 128 bits. [With regard to using a key
length other than 128 bits, the main thing that changes in AES is how you generate the key schedule from the key —
an issue I address at the end of Section 8.8.1. The notion of key schedule in AES is explained in Sections 8.2 and
8.8.] • Encryption consists of 10 rounds of processing for 128-bit keys, 12 rounds for 192-bit keys, and 14 rounds for
256-bit keys. • Except for the last round in each case, all other rounds are identical. • Each round of processing
includes one single-byte based substitution step, a row-wise permutation step, a column-wise mixing.
AES Key Expansion AES Key Expansion
Use four byte words called w Use four byte words called wi. Subkey = 4 words. . Subkey = 4 words.
For AES For AES-128:
First subkey (w3,w2,w1,w0) = cipher keyFirst subkey (w3,w2,w1,w0) = cipher key
Other words are calculated as follows: Other words are calculated as follows:

VIII. Cooperative Provable Data Possession Scheme
This work addresses the construction of an efficient PDP scheme for distributed cloud storage to support
data migration and scalability of service, in which we consider the existence of multiple cloud service providers to
cooperatively store and maintain the clients’ data. It presents a cooperative PDP (CPDP) scheme based on
homomorphic verifiable response and hash index hierarchy. Multi-prover zero knowledge proof system is used to
prove the security of this scheme, which can satisfy knowledge soundness, completeness and zero-knowledge
properties.
A. Hash index hierarchy:
To support distributed cloud storage, architecture used in cooperative PDP scheme as shown in fig. 2. Our
structure has a hierarchy structure which resembles a natural representation of file storage. This structure consists of
three layers to represent relationships among all blocks for stored resources. This hierarchy structure and layers are
described as follows:
1) Express Layer: This layer offers an abstract representation of the stored resources;
2) Service Layer: This layer offers and manages cloud storage services; and
3) Storage Layer: This layer represents data storage on many physical devices.
Fig.4 Hash index hierarchy.
This hierarchy used to organize data blocks from multiple CSP services into a large size file by shading
their differences among these cloud storage systems. In Figure the resource in Express Layer are split and stored into
three CSPs that are indicated by different colors are shown in Service Layer. After that each CSP fragments and
stores the assigned data into the storage servers in Storage Layer. It also makes use of colors to distinguish different
CSPs. Moreover, it follows the logical order of the data blocks to organize the Storage Layer.
B. Homomorphic Verifiable Response:
Homomorphic Verifiable Responses (HVR), which is used to integrate multiple responses from the
different CSPs in CPDP scheme. If given two responses and for two challenges and from two CSPs, there exist an
efficient algorithm to combine them into a response corresponding to the sum of the challenges ∪ then a response
is called homomorphic verifiable response in a PDP protocol. Homomorphic verifiable response is the key technique
of CPDP because it not only reduces the communication bandwidth, but also hides the location of outsourced data in
the distributed cloud storage environment.

DOI: 10.9790/0661-1803035056 www.iosrjournals.org 56 | Page
C. Security Analysis:
Multi-prover zero-knowledge proof system is directly used for security, which satisfies following properties:
1) Collision resistant for index-hash hierarchy: The indexhash hierarchy in CPDP scheme is collision resistant,
even if the client generates files with the same file name and cloud name collision doesn’t occur there.
2) Completeness property of verification: In this scheme, the completeness property implies public verifiability
property. Due to this property allows client as well as anyone other than client (data owner) can challenge the
cloud server for data integrity and data ownership without the need for any secret information.
3) Zero-knowledge property of verification: This paper makes use of the zero-knowledge property to preserve the
privacy of data blocks and signature tags. Initially, randomness is adopted into the CSPs’ responses in order to
resist the data leakage attacks.
Knowledge soundness of verification:
The soundness means that it is infeasible to fool the verifier to accept false statements. Often, the soundness
can also be considered as a stricter notion of unforge ability for file tags to avoid cheating the ownership. This
denotes that the CSPs, even if collusion is tried, cannot be tampered with the data or forge the data tags if the
soundness property holds. Thus CPDP scheme can resist the tag forgery attacks to avoid cheating the CSPs’
ownership.
IX. Conclusion
Cloud is designed to provide a service to the external users. To compensate their needs the resources should
be highly available. In this survey, it gives overview about cloud availability and various integrity verification
techniques. In addition, comparative study of various availability and integrity verification schemes and its
methodology are classified along with their adaptation to single/multi cloud environment.This paper formalizes the
ID-DPDP system model and security model. ID-DPDP protocol works efficiently in multi cloud environment.
Besides of the elimination of certificate management, our ID-DPDP protocol has also flexibility and high efficiency.
At the same time, the proposed ID-DPDP protocol can realize private verification, delegated verification and public
verification based on the client’s authorization.
