Data get to control is a powerful method to guarantee the data security in the cloud. Because of information
out sourcing and un confided in cloud servers, the information get to control turns into a testing issue in cloud
storage systems. Cipher text-Policy Attribute Based Encryption (CP-ABE) is viewed as a standout amongst
the most reasonable advancements for information get to control in distributed storage, since it gives
straightforward control access to the owners. It is hard to implement the existing CP-ABE schemes to access
the information from cloud storage systems. we propose a plan to structure the information securing control in
a revocable multi-expert CP-ABE conspire from cloud storage system
In this paper, we consider ‘secure attribute based system with short ciphertext’ is a tool for implementing fine-grained access control over encrypted data, and is conceptually similar to traditional access control methods such as Role-Based Access Control. However, current ‘secure attribute based system with short ciphertext’ schemes suffer from the issue of having long decryption keys, in which the size is linear to and dependent on the number of attributes.Ciphertext-Policy ABE (CP-ABE) provides a scalable way of encrypting data such that the encryptor defines the attribute set that the decryptor needs to possess in order to decrypt the ciphertext. We propose a novel ‘secure attribute based system with short ciphertext’ scheme with constant-size decryption keys independent of the number of attributes. We found that the size can be as small as 672 bits.
In attribute based encryption (ABE) scheme, attributes plays a very important role. Attribute –based encryption provides privacy protection for the users by a set of attributes. Now a days as cloud is most widely used in mostly all fields so there is need of keeping data more secure and confidential which is outsourced on the cloud. Security of the data in cloud database server is the key area of concern in the acceptance of cloud. It is required very high degree of privacy and authentication. In existing system used hierarchical authorization structure to reduce the burden and risk of a single authority .this paper proposes a hierarchical attribute based encryption which directly provides attribute value by user as well as data stored in different types of media.

Cloud computing is one of the emerge technologies in order to outsource huge volume of data inters of storage and sharing. To protect the data and privacy of users the access control methods ensure that authorized users access the data and the system. Fine grained-approach is the appropriate method for data access control in cloud storage. However, CP-ABE schemes to data access control for cloud storage systems are difficult because of the attribute revocation problem. Specifically, in this paper we investigate on revocable multi-authority Fine-grained-Scheme performance.

Access Policy Management For OSN Using Network RelationshipsIJMTST Journal
In the online social networks (OSN) users and resources are interconnected via various types of
relationships. The relationships are one-to-one, one-to-many, many-to-one, and many-to-many like that. Now
a day’s online social networks plays crucial role to monitor and to control the access of the resources. In the
OSN, online provider should be enabled to specify which access permission can be granted in terms of
existing relationships. In this work we used user-to-user relationship based access control model. Access
control policies decide which permissions can be granted to the requested users based on their requests and
we are using two path checking algorithms namely DFS and BFS to determine the path existence between
users as well as the requested user is authenticated user or not.

Attribute-based encryption (ABE) is a public-key based one-to-many encryption that allows users to encrypt and decrypt data based on user attributes.
A promising application of ABE is flexible access control of encrypted data stored in the cloud, using access polices and ascribed attributes associated with private keys and ciphertexts.One of the main efficiency drawbacks of the existing ABE schemes is that decryption involves expensive pairing operations and the number of such operations grows with the complexity of the access policy. Recently, Green et al. proposed an ABE system with outsourced decryption that largely eliminates the decryption overhead for users.
In such a system, a user provides an untrusted server, say a cloud service provider, with a transformation key that allows the cloud to translate any ABE cipher text satisfied by that user’s attributes or access policy into a simple cipher text, and it only incurs a small computational overhead for the user to recover the plaintext from the transformed cipher text.
Security of an ABE system with outsourced decryption ensures that an adversary (including a malicious cloud) will not be able to learn anything about the encrypted message; however, it does not guarantee the correctness of the transformation done by the cloud.
In this paper, we consider a new requirement of ABE with outsourced decryption: verifiability. Informally, verifiability guarantees that a user can efficiently check if the transformation is done correctly.
We give the formal model of ABE with verifiable outsourced decryption and propose a concrete scheme. We prove that our new scheme is both secure and verifiable, without relying on random oracles.
Finally, we show an implementation of our scheme and result of performance measurements, which indicates a significant reduction on computing resources imposed on users.

The Recent Trend: Vigorous unidentified validation access control system with...IJERA Editor
Service Providers can grow their business by selling our cloud authentication service that can be fully branded
to the Service Provider or if required a Service. The proposed enhanced decentralized access control scheme for
secure data storage in clouds that supports anonymous authentication. In the proposed scheme, the cloud verifies
the authenticity of the series without knowing the user’s identity before storing data. The scheme also has the
added feature of access control in which only valid users are able to decrypt the stored information. The scheme
prevents replay attacks and supports creation, modification, and reading data stored in the cloud. It addresses
user revocation. Moreover, our authentication and access control scheme is decentralized and robust, unlike
other access control schemes designed for clouds which are centralized. The communication, hiding attributes,
increasing high security in access, computation, and storage overheads are comparable to centralized
approaches.
In Existing, it is based on ABE (attribute based encryption) technique which is a centralized approach, where a
single Key Distribution Centre (KDC) distributes secret keys and attributes to all users using asymmetric key
approach. We propose a new decentralized access control method for storing data by providing security in
clouds and also we hide the attributes and access rule of a user. The cloud validates the authentication of the
sequence without knowing the users characteristics previous to the data store. By using this approach only
certified users have right to use the suitable attributes. In future, time based file revocation scheme can be used
to assure the deletion of a file. When time limit of a file expires, we implement the policy based renewal of time
to that file.

Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications
without the burden of local hardware and software management. Though the benefits are clear, such a service is also
relinquishing users’ physical possession of their outsourced data, which inevitably poses new security risks towards the
correctness of the data in the cloud. In order to address this new problem and further achieve a secure and dependable cloud
storage service, we propose in this paper we develop a new cryptosystem for fine-grained sharing of encrypted data that we call
Key-Policy Attribute-Based Encryption (KP-ABE). In our cryptosystem, ciphertexts are labelled with sets of attributes and private
keys are associated with access structures that control which cipher texts a user is able to decrypt. Attribute-based encryption
(ABE) has been envisioned as a promising cryptographic primitive for realizing secure and flexible access control. HASBE
extends the ASBE algorithm with a hierarchical structure to improve scalability and flexibility while at the same time inherits
the feature of fine-grained access control of ASBE.

Several Data Security Methodology has been noticed, with recent adoption and spreading of data sharing. One of the most interesting and definitive approach is Cipher text-Policy Attribute-Based Encryption (CP-ABE).CP-ABE provides us with the indulgement of the access policies and its updates. It is used to set or control outsourcing of data sharing; it deals with the issues in CP-ABE. This solution allows encryptor to deals with the access control with respect to the access formula. The lacking of reliability factor lead to weaken the system, therefore we will amplify CB-ABE by introducing some factor. Key Generation center (KGC) and data storing center are the highlighted factors. KGC deals with the drawback of Key escrow problem. As KGC can decrypt the users data as per KGC`s concerns, causing threat to the data sharing Systems. This is not favorable for the distributed scheme where KGC is not trustworthy. Along with the key escrow problem, we will be concerning with the problem of key-revocation that is degradation because of windows of vulnerability. These issues are solved by exploiting the features characteristics of Architecture. The problem of key-escrow is resolved using 2-pc protocol. And Key-revocation is proceeding by using proxy encryption.
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.
A Secure, Scalable, Flexible and Fine-Grained Access Control Using Hierarchic...Editor IJCATR
Cloud Computing is going to be very popular technology in IT enterprises. For any enterprise the data stored is very huge
and invaluable. Since all tasks are performed through network it has become vital to have the secured use of legitimate data. In cloud
computing the most important matter of concern are data security and privacy along with flexibility, scalability and fine grained access
control of data being the other requirements to be maintained by cloud systems Access control is one of the prominent research topics
and hence various schemes have been proposed and implemented. But most of them do not provide flexibility, scalability and fine
grained access control of the data on the cloud. In order to address the issues of flexibility, scalability and fine grained access control
of remotely stored data on cloud we have proposed the hierarchical attribute set-based encryption (HASBE) which is the extension of
attribute- set-based encryption(ASBE) with a hierarchical structure of users. The proposed scheme achieves scalability by handling the
authority to appropriate entity in the hierarchical structure, inherits flexibility by allowing easy transfer and access to the data in case
of location switch. It provides fine grained access control of data by showing only the requested and authorized details to the user thus
improving the performance of the system. In addition, it provides efficient user revocation within expiration time, request to view
extra-attributes and privacy in the intra-level hierarchy is achieved. Thus the scheme is implemented to show that is efficient in access
control of data as well as security of data stored on cloud with comprehensive experiments
A Secure & Scalable Access Method in Cloud Computingijsrd.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, The proposed scheme not only achieves scalability due to its hierarchical structure, but also inherits flexibility. We implement our scheme and show that it is both efficient and flexible in dealing with access control for outsourced data in cloud computing with comprehensive experiments.
Attribute Based Encryption with Attribute Hiding in Cloud StorageIJTET Journal
Abstract— Cloud computing is widely used technologies that provides on-demand self services. One of the main services is cloud storage. Cloud storage is used to store up and access the data anywhere from the cloud. To have a have power over the data we necessitate a fine-grained access control system. One of the Fine-grained access control system is Attribute Based Encryption (ABE). The ABE system is used to provide access control using attributes. Attributes may be anything. For example, it may person‟s roles or date. In ABE system the encryption phase consists of access rules. Rules are depended on the data owner and the consumer. It is not hidden in the existing systems. Through this, users can get the useful information from access rules without decryption. To improve the effectiveness of the ABE system, a new ABE algorithm is proposed. The proposed ABE algorithm has the features hiding Attributes and Access Policies. Through this, users getting useful information from the cipher text are avoided. Attributes and Access policies are hidden by the hash function and polynomial functions. The proposed ABE system ensures data privacy and policy privacy. Through this, the efficiency of the attribute based encryption system is improved.

Access Control and Revocation for Digital Assets on Cloud with Consideration ...IJERA Editor
In cloud computing applications, users’ data and applications are hosted by cloud providers. With internet and cloud availability increasing numbers of people are storing their content on cloud. Also with presence of social networking, contents stored on cloud are also shared. This requires more security for the contents on cloud. Traditional security solution address only encryption, decryption of data on cloud and its access control , but with this new trend of sharing, the scope of security becomes even higher. In this paper we propose a solution of integrated access control for contents shared on cloud and its efficient revocation.
An Improved Integrated Hash and Attributed based Encryption Model on High Dim...IJECEIAES
Cloud computing is a distributed architecture where user can store their private, public or any application software components on it. Many cloud based privacy protection solutions have been implemented, however most of them only focus on limited data resources and storage format. Data confidentiality and inefficient data access methods are the major issues which block the cloud users to store their high dimensional data. With more and more cloud based applications are being available and stored on various cloud servers, a novel multi-user based privacy protection mechanism need to design and develop to improve the privacy protection on high dimensional data. In this paper, a novel integrity algorithm with attribute based encryption model was implemented to ensure confidentiality for high dimensional data security on cloud storage. The main objective of this model is to store, transmit and retrieve the high dimensional cloud data with low computational time and high security. Experimental results show that the proposed model has high data scalability, less computational time and low memory usage compared to traditional cloud based privacy protection models.
Water billing management system project report.pdfKamal Acharya
Our project entitled “Water Billing Management System” aims is to generate Water bill with all the charges and penalty. Manual system that is employed is extremely laborious and quite inadequate. It only makes the process more difficult and hard.
The aim of our project is to develop a system that is meant to partially computerize the work performed in the Water Board like generating monthly Water bill, record of consuming unit of water, store record of the customer and previous unpaid record.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

authority CP-ABE scheme, where an efficient and
secure revocation method is proposed to solve the
attribute revocation problem in the system. Our
attribute revocation method is efficient in the sense
that it incurs less communication cost and
computation cost, and is secure in the sense that it
can achieve both backward security (The revoked
user cannot decrypt any new cipher text that
requires the revoked attribute to decrypt)and
forward security (The newly joined user can also
decrypt the previously published ciphertexts1, if it
has sufficient attributes). Our scheme does not
require the server to be fully trusted, because the
key update is enforced by each attribute authority
not the server. Even if the server is not semi trusted
in some scenarios, our scheme can still guarantee
the backward security. Then, we apply our
proposed revocable multi-authority CP-ABE
scheme as the underlying techniques to construct
the expressive and secure data access control
scheme for multi-authority cloud storage systems.
II. PROPOSED METHOD
In this paper, In the existing system the
Ciphertext-Policy Attribute-based Encryption
(CP-ABE) algorithm is one of the most suitable
technologies for data access control in cloud
storage systems .In CP-ABE scheme, there is an
authority that is responsible for attribute
management and key distribution.Revocable multi
authority CP-ABE scheme, where an efficient and
secure revocation method is proposed to solve the
attribute revocation problem in the system and is
secure in the sense that it can achieve both
backward and forward security. We apply this
multi-authority CP-ABE scheme as the underlying
techniques to construct the expressive and secure
data access control scheme for multi-authority
cloud storage systems.
III. RELATED WORK
Introduced the attribute basedencryption (ABE)
for enforced access control through publickey
cryptography. The main goal for these models is to
provide security and access control. The main
aspects are toprovide flexibility, scalability and fine
grained access control.In classical model, this can
be achieved only when user andserver are in a
trusted domain. But what if their domains arenot
trusted or not same? So, the new access control
schemethat is „Attribute Based Encryption (ABE)‟
scheme wasintroduced which consist of key policy
attribute basedencryption (KP-ABE). As compared
with classical model,KP-ABE provided fine grained
access control. However itfails with respect to
flexibility and scalability when authoritiesat
multiple levels are considered.
In ABE scheme both the user secret key and the
ciphertextare associated with a set of attributes. A
user is able todecrypt the cipher-text if and only if
at least a threshold number of attributes overlap
between the cipher-text and usersecret key.
Different from traditional public key
cryptographysuch as Identity-Based Encryption,
ABE is implemented for one-to many encryption in
which cipher-texts are not necessarily encrypted to
one particular user, it may be for more than one
number of users. In Sahai and Waters ABE
scheme, the threshold semantics are not very
expressive to be used for designing more general
access control system. Attribute-Based Encryption
(ABE) in which policies are specified and enforced
in the encryption algorithm itself. The existing ABE
schemes are of two types. They are Key-Policy ABE
(KP-ABE) scheme and Ciphertext-Policy ABE
(CPABE) scheme.
Key Policy Attribute Based
Encryption(KP-ABE):-
To enable more general access control, V. Goyal,
O.Pandey, A. Sahai, and B. Waters proposed a
key-policyattribute-based encryption (KP-ABE)
scheme. It is themodified form of classical model of
ABE. Exploring KP-ABEscheme, attribute policies
are associated with keys and data isassociated
with attributes. The keys only associated with
thepolicy that is to be satisfied by the attributes
that areassociating the data can decrypt the data.
Key Policy AttributeBased Encryption (KP-ABE)

designed for one-to-manycommunications. In this
scheme, data is associated with theattributes for
which a public key is defined for eachEncrypter,
that is who encrypts the data, is associated with

theset of attributes to the data or message by
encrypting it with apublic key. Users are assigned
with an access tree structureover the data
attributes. The nodes of the access tree are
thethreshold gates. The leaf nodes are associated
with attributes.
The secret key of the user is defined to reflect the
access treestructure. Hence, the user is able to
decrypt the message thatis a ciphertext if and only
if the data attributes satisfy theaccess tree
structure. In KP-ABE, a set of attributes
isassociated with ciphertext and the user‟s
decryption key isassociated with a monotonic
access tree structure. Whenthe attributes
associated with the cipher text satisfy the access
tree structure, then the user can decrypt the
ciphertext.

an identity based encryption scheme, each user is
identified by a unique identity string. An attribute
based encryption scheme (ABE), in contrast, is a
scheme in which each user is identified by a set of
attributes, and some function of those attributes is
used to determine decryption ability for each
cipher text. Sahai and Waters introduced a single
authority attribute encryption scheme and left
open the question of whether a scheme could be
constructed in which multiple authorities were
allowed to distribute attributes [SW05]. We answer
this question in the affirmative.Our scheme allows
any polynomial number of independent authorities
to monitor attributes and distribute secret keys. An
encryptor can choose, for each authority, a number
dk and a set of attributes; he can then encrypt a
message such that a user can only decrypt if he
has at least dk of the given attributes from each
authority k. Our scheme can tolerate an arbitrary
number of corrupt authorities. We also show how
to apply our techniques to achieve a multiauthority
version of the large universe fine grained access
control ABE presented by Gopal et al.
2.‘‘Improving Privacy and Security in
Multi-Authority Attribute-Based Encryption,’’
AUTHORS:M. Chase and S.S.M. Chow
Attribute based encryption (ABE) [13] determines
decryption ability based on a user's attributes. In a
multi-authority ABE scheme, multiple
attribute-authorities monitor different sets of
attributes and issue corresponding decryption
keys to users and encryptors can require that a
user obtain keys for appropriate attributes from
each authority before decrypting a message. Chase
[5] gave a multi-authority ABE scheme using the
concepts of a trusted central authority (CA) and
global identifiers (GID). However, the CA in that
construction has the power to decrypt every cipher
text, which seems somehow contradictory to the
original goal of distributing control over many
potentially untrusted authorities. Moreover, in that
construction, the use of a consistent GID allowed
the authorities to combine their information to
build a full profile with all of a user's attributes,
which unnecessarily compromises the privacy of
the user. In this paper, we propose a solution
which removes the trusted central authority, and
protects the users' privacy by preventing the
authorities from pooling their information on
particular users, thus making ABE more usable in
practice.
3.‘‘Decentralizing Attribute-Based Encryption,’’
AUTHORS: A.B. Lewko and B. Waters
We propose a Multi-Authority Attribute-Based
Encryption (ABE) system. In our system, any party
can become an authority and there is no
requirement for any global coordination other than
the creation of an initial set of common reference
parameters. A party can simply act as an ABE
authority by creating a public key and issuing
private keys to different users that reflect their
attributes. A user can encrypt data in terms of any
Boolean formula over attributes issued from any
chosen set of authorities. Finally, our system does
not require any central authority.
In constructing our system, our largest technical
hurdle is to make it collusion resistant. Prior
Attribute-Based Encryption systems achieved
collusion resistance when the ABE system
authority “tied” together different components
(representing different attributes) of a user‟s
private key by randomizing the key. However, in
our system each component will come from a
potentially different authority, where we assume
no coordination between such authorities. We
create new techniques to tie key components
together and prevent collusion attacks between
users with different global identifiers. We prove our
system secure using the recent dual system
encryption methodology where the security proof
works by first converting the challenge cipher text
and private keys to a semi-functional form and
then arguing security. We follow a recent variant of
the dual system proof technique due to Lewko and
Waters and build our system using bilinear groups
of Composite order. We prove security under

similar static assumptions to the LW paper in the
random oracle model.
V. CONCLUSION
In this paper Cloud computing brings great
convenience for people. In this project, we build a
cost-effective and secure datasharing system in
cloud computing, we propose a revocable
multi-authority CPABE scheme that can
supportefficient attribute revocation. Then, we
constructed an effective data access control
scheme for multi-authoritycloud storage systems.
We also proved that our scheme was provable
secure in the random oracle model. Therevocable
multi-authority CPABE is a promising technique,
which can be applied in any remote storage
systemsand online social networks etc.
