Efficient Multi Server Authentication and Hybrid Authentication MethodIJCERT
Password is used for authentication on many major client-server system, websites etc. Client and a server share a password using Password-authenticated key exchange to authenticate each other and establish a cryptographic key by exchanging generated exchanges. In this scenario, all the passwords are stored in a single server which will authenticate the client. If the server stopped working or compromised, for example, hacking or even insider attack, passwords stored in database will become publicly known. This system proposes that setting where multiple servers which are used to, so that the password can be split in these servers authenticate client and if one server is compromised, the attacker still cannot be able to view the client’s information from the compromised server. This system uses the Advance encryption standard algorithm encryption and for key exchange and some formulae to store the password in multiple server. This system also has the hybrid authentication as another phase to make it more secure and efficient. In the given authentication schema we also use SMS integration API for two step verification.
This document summarizes a research paper on outsourced attribute-based signatures (OABS). It discusses how existing attribute-based signature (ABS) schemes have high computational costs for signing that scale with the complexity of the predicate formula. To address this, the paper proposes two new OABS schemes that reduce the computation required for signing by outsourcing parts of the signing process to an untrusted cloud server. The first scheme reduces the number of exponentiations in signing from O(d) to O(1), while the second builds on an existing construction and reduces exponentiations from O(d^2) to O(d). Security analysis shows the schemes achieve unforgeability and privacy.
Kerberos is a network authentication protocol that was developed at MIT in the 1980s to allow nodes communicating over an insecure network to verify each other's identity. It uses tickets and session keys to allow clients and servers to communicate over a non-secure network and establish the identity of the users and servers. The Kerberos authentication process involves three main exchanges between the client, authentication server (KDC), and target server to authenticate users and allow access to services.
Kerberos is a network authentication protocol that provides secure authentication for client/server applications. It uses secret-key cryptography and relies on a trusted third party called the Key Distribution Center (KDC) which is aware of all systems on the network. Kerberos introduces tickets that allow a client access to a server after initial authentication with the KDC. The authentication process involves the client receiving a ticket-granting ticket from the KDC and then exchanging messages with the ticket-granting service and target server to gain access.

This document describes a proposed system for an identity-based encryption scheme with outsourced revocation in cloud computing. The proposed system introduces a new entity called a Key Update Cloud Service Provider (KU-CSP) that handles most of the key generation operations during key issuing and updating, reducing the workload of the Private Key Generator (PKG). Specifically, the system uses a hybrid private key for each user consisting of an identity component generated by the PKG and a time component updated by the KU-CSP. This allows efficient revocation by periodically updating users' time components while keeping the identity component fixed.

A LIGHT-WEIGHT MUTUAL AUTHENTICATION AND KEY-EXCHANGE PROTOCOL BASED ON ELLIP...IJNSA Journal
Wireless devices are characterized by low computational power and memory. Hence security protocols dealing with these devices have to be designed to give minimal computational and memory load. We present an efficient authentication and key exchange protocol for low-end wireless clients and high end servers, which is overall nearly three times as fast as comparable protocols. The basic idea of our protocol is to use symmetric key encryption in place of public key encryption wherever possible.
Kerberos is a network authentication protocol that uses "tickets" to allow nodes on a non-secure network to prove their identity to one another securely. It provides mutual authentication and is protected against eavesdropping and replay attacks. Kerberos uses a central authentication server and ticket granting services to authenticate clients and allow them secure access to other services on the network. However, Kerberos has some limitations such as being vulnerable if the central authentication server is compromised.

This document discusses a proposed method for finding statistically significant co-location and segregation patterns in spatial domains. Existing approaches have shortcomings like relying on user thresholds and not accounting for spatial autocorrelation. The proposed method introduces a new definition of these patterns, models the null distribution of features to consider spatial autocorrelation, and designs an algorithm to find both types of patterns. It also develops strategies to reduce computational cost and further speed up the algorithm using neighborhood approximations. The method is empirically evaluated on synthetic and real data sets.

The document proposes two outsourced attribute-based signature (OABS) schemes that reduce the computational overhead of signing for resource-limited users by outsourcing intensive computations to a cloud service provider. The first scheme reduces the number of exponentiations in signing from linear to constant time, while the second builds on an existing construction to reduce exponentiations from quadratic to linear time. Both schemes are proven secure while allowing for outsourced verification through the introduction of an additional verifying-cloud service provider entity under the assumption they do not collude with the signing-cloud provider.

Identifying the Performance Efficiency Of Attribute Based Encryption With Sec...IJSRD
Attribute-based encryption (ABE) can be used for the encryption of data with attributes and logs. Instead of encrypting each part of a log with the keys of all recipients, it is possible to encrypt the log only with attributes which match recipient’s attributes. This primitive can also be used for broadcast encryption in order to decrease the number of keys used. Here the access control will be given with the keys and the attributes. The outsourcing computation cost will be comparatively less when compared to the existing system. The data will be shared between the two users if and only if the key matches. In addition, for the first time, we propose an outsourced ABE construction which provides check ability of the outsourced computation results in an efficient way. The performance analysis has been proven this method to be more secured.

This document summarizes an academic paper that proposes an attribute-based encryption scheme with verifiable outsourced decryption. Existing schemes offload decryption to an untrusted server but do not verify the correctness of the transformation. The proposed scheme modifies the security model to allow for verification and constructs a concrete ABE system where a user can efficiently check that the server performed the decryption transformation correctly, without relying on random oracles. The scheme substantially reduces the computation required for decryption on resource-limited devices.

Providing user security guarantees in public infrastructure cloudsKamal Spring
The infrastructure cloud (IaaS) service model offers improved resource flexibility and availability, where tenants – insulated from the minutiae of hardware maintenance – rent computing resources to deploy and operate complex systems. Large-scale services running on IaaS platforms demonstrate the viability of this model; nevertheless, many organizations operating on sensitive data avoid migrating operations to IaaS platforms due to security concerns. In this paper, we describe a framework for data and operation security in IaaS, consisting of protocols for a trusted launch of virtual machines and domain-based storage protection. We continue with an extensive theoretical analysis with proofs about protocol resistance against attacks in the defined threat model. The protocols allow trust to be established by remotely attesting host platform configuration prior to launching guest virtual machines and ensure confidentiality of data in remote storage, with encryption keys maintained outside of the IaaS domain. Presented experimental results demonstrate the validity and efficiency of the proposed protocols. The framework prototype was implemented on a test bed operating a public electronic health record system, showing that the proposed protocols can be integrated into existing cloud environments.
IRJET- Developing an Algorithm to Detect Malware in CloudIRJET Journal
This document discusses developing an algorithm to detect malware in the cloud. It begins by reviewing existing malware detection methods and their limitations for cloud environments. It then presents a new algorithm that uses one-class support vector machines (SVMs) to detect anomalies at the hypervisor level through features collected from the system and network levels of cloud nodes. The algorithm is able to achieve over 90% detection accuracy for different types of malware and denial-of-service attacks. It assesses the benefits of using both system-level and network-level information depending on the attack type. The approach of using dedicated monitoring agents per virtual machine makes it well-suited for cloud environments and able to detect new malware strains without prior knowledge of their functionality.

This document proposes a novel approach to securely control and access data stored in the cloud using Ciphertext-Policy Attribute-Based Encryption (CP-ABE). The approach aims to address abuse of access credentials by tracing malicious insiders and revoking their access. It presents two new CP-ABE frameworks that allow traceability of malicious cloud clients, identification of misbehaving authorities, and auditing without requiring extensive storage. The frameworks provide fine-grained access control and can revoke credentials of traced attackers.

This document proposes an attribute-based encryption scheme with verifiable outsourced decryption. Existing attribute-based encryption schemes have expensive decryption costs due to pairing operations. To address this, prior work introduced outsourced decryption using a transformation key, but did not verify the correctness of the transformation. The proposed scheme modifies the model to allow verification and constructs a concrete scheme that proves security without random oracles, while substantially reducing computation time for resource-limited devices to recover plaintexts.

It discusses using one-time passwords and unique codes for login along with blockchain technology to securely store data in the cloud. The framework aims to improve security, securely share data online, and secure cloud data storage. It presents a system architecture with three modules - data owner, user, and authority - to allow data owners to securely upload files via blockchain that users can view and download with authentication.
Public Verifiability in Cloud Computing Using Signcryption Based on Elliptic ...IOSR Journals
This document proposes a scheme for public verifiability in cloud computing using signcryption based on elliptic curves. The scheme aims to ensure the correctness of user's data stored on the cloud without demanding the user's time, feasibility, or resources. It utilizes erasure-correcting codes, homomorphic tokens, and distributed verification to guarantee data dependability and allow detection and localization of data errors on misbehaving servers. Signcryption and unsigncryption based on elliptic curves are used to enforce public verifiability, improving on a previous cloud storage model.

Existing work addresses when data values on certain dimensions are unknown, but real-life data like from sensors may have missing dimension information as well. The proposed system develops a probabilistic framework to model similarity search on dimension incomplete data, allowing users to find similar objects with probability guarantees. It derives lower and upper bounds on the probability of similarity to efficiently filter irrelevant objects without examining all missing dimension combinations. Experimental results on real data demonstrate the approach's effectiveness and efficiency.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Secure Outsourced Attribute-Based Signatures
ABSTRACT
Attribute-based signature (ABS) is a useful variant of digital signature, which enables
users to sign messages over attributes without revealing any information other than the
fact that they have attested to the messages. However, heavy computational cost is
required during signing in existing work of ABS, which grows linearly with the size of
the predicate formula. As a result, this presents a significant challenge for resource-limited
users (such as mobile devices) to perform such heavy computation independently.
Aiming at tackling the challenge above, we propose and formalize a new paradigm called
OABS, in which the computational overhead at user side is greatly reduced through
outsourcing such intensive computation to an untrusted signing-cloud service provider
(S-CSP). Furthermore, we apply this novel paradigm to existingABS to reduce
complexity and present two schemes, i) in the first OABS scheme, the number of
exponentiations involving in signing is reduced from O(d) to O(1) (nearly three), where d
is the upper bound of threshold value defined in the predicate; ii) our second scheme is
built on Herranz et al's construction with constant-size signatures. The number of
exponentiations in signing is reduced from O(d2) to O(d) and the communication
overhead is O(1). Security analysis demonstrates that both OABS schemes are secure in
terms of the unforgeability and attribute- signer privacy definitions specified in the
proposed security model. Finally, to allow for high efficiency and exibility, we discuss
2. extensions of OABS and show how to achieve accountability and outsourced verification
as well.
EXISTING SYSTEM:
We specify that existing work of ABS requires a large number of exponentiations in
signing. Thecomplexity commonly grows linearly with the size of the predicate formule
in threshold ABS6. Such inefficiency becomes even more serious for ABS with more
expressive predicate. The problem that how to securely outsource different kinds
ofexpensive computations has drew considerable attention from theoretical computer
science community.
PROPOSED SYSTEM:
The proposed OABS scheme with outsourced verification reduces the computation load
at signerside through delivering computation to V-CSP but only lefting two
exponentiations locally. Because the outsourcing verification method is the same as, the
security can be also guaranteed based on the assumption that the S-CSP does not collude
with the V-CSP. In another word, V-CSP cannot cheat to let an invalid signature pass the
verification algorithm becauseis blinded and not available to V-CSP
PROBLEM STATEMENT:
There are three entities involved in our OABS system, namely, the attribute authority,
users (includesigners and verifiers), and S-CSP. Typically, the signers obtain their private
keys from attribute authority,with which they are able to sign messages later for any
predicate satisfied by the possessedattributes. Verifiers will be convinced of the fact that
whether a signature is from one of the userswhose attributes satisfy the signing predicate,
but remaining completely ignorant of the identity of thesigner. Different from the
definition of traditional ABS an additional entity S-CSP is introduced. Specifically, S-CSP
is to finish the outsourced expensive tasks in signing phase and relieve
thecomputational burden at signer side.
SCOPE:
3. The proposed scheme of OABS must satisfy outsource able requirement. Specifically, the
runningtime of Sign must be less than directly computing the signature itself. In original
ABS construction, it requires single-based exponentiations to generate the signature.
However, sincemultiple exponentiations have been delivered to S-CSP, in OABS-I, the
signing algorithm Sign simplyrequires 3 single-based exponentiations, which is
independent of the attribute to be signed.We also specify that our technique in OABS-I
allows S-CSP to perform delegated signing byemploying an AND gate at private key for
each user. Therefore, to generate an outsourcing key,attribute authority has to compute
exponentiations in G, which is linear with the size ofrequest attribute set Ω. Fortunately,
in practical, the generation is allowed to be performed once forall. After obtaining private
key and outsourcing key from authority, user is able to (delegated) signany message with
it. Such amortized computation cost of generating the outsourcing key is rather lowcost.
Moreover, we consider a scenario that user has limited computation and storage ability.
In thiscase, the outsourcing key can be firstly generated by authority and sent to S-CSP.
Therefore, user onlyneeds to store a small-sized componentlocally but still maintaining
signing capability.
MODULE DESCRIPTION:
Number of Modules
After careful analysis the system has been identified to have the following modules:
1. Cloud Computing Module.
2. Attribute Based Signature Module.
3. OutsourceABS Computation Module.
4. OABS With Outsource Verification Module.
1. Cloud Computing Module:
4. Cloud computing, provides thefeasibility to reduce the computation overhead at user side
by outsourcing the computation of signingto a signing-cloud service provider (S-CSP).
This presents a significant challenge for users that manage and viewprivate data on
mobile devices where processors are often one to two orders of magnitude slower
thantheir desktop counterparts. We employ a hybrid privatekey by introducing a default
attribute for all the users in the system. The private key component for user'sattributes
(denoted as outsourcing key OK in this paper) which is to be utilized by S-CSP to
computethe outsourced signature; ii) the private key component for the default attribute
which is to be utilizedby signer to generate a normal ABS signature from the outsourced
signature returned from S-CSP.
2. Attribute Based Signature Module:
Attribute-based signature (ABS) enables a party to sign a messagewith _fine-grained
access control over identifying information. Specifically, in an ABS system, users obtain
their attribute private keys from an attribute authority, with which they can later sign
messagesfor any predicate satisfied by their attributes. A verifier will be convinced of the
fact that whether thesigner's attributes satisfy the signing predicate while remaining
completely ignorant of the identity of
signer. ABS is much useful in a wide range of applications including private access
control, anonymouscredentials, trust negotiations, distributed access control for ad hoc
networks, attribute-basedmessaging.
3.OutsourceABS Computation Module:
Outsourced attribute-based signaturescheme OABS consists of five probabilistic
polynomial-time algorithms below:
Setup: It takes as input the security parameter _, attribute universe U and an
auxiliaryinformation d. It outputs the public key PK and the master key MK.
Key Gen (MK; Ω) : For each user's private key request on attribute set Ω, the private key
generation algorithm takes as input the master key MK and the attribute set Ω. It outputs
the user's privatekey SK and the outsourcing key OK.
5. Sign out (OK; Ω; _): The outsourced signing algorithm takes as input the outsourcing key
OK,the corresponding attribute set Ω and the predicate _. It outputs the partial signature
_part.
Sign(SK;M; _part; _) : The signing algorithm takes as input the private key SK, the
message M,the partial signature _part and the corresponding predicate _. It outputs the
signature _ of messageM with the predicate _.
Verify(M; _; _; PK) : The verifying algorithm takes as input a message M, the signature
_,the predicate _ and public key PK. It outputs 1 if the original signature is deemed valid
and 0otherwise.
5. OABS With Outsource Verification Module:
This technique can only guarantee the correctness of outsourced computation with
accountability, it cannot check the correctness and detect the misbehaves of S-CSP on
spot. To solve this problem, we provide another solution to verify the outsourced
signature with low computational cost by introducing another independent entity called
verifying-cloud service provider (V-CSP). We also introduce an assumption that the S-CSP
and V-CSP will not collude. Actually, such assumption has also appearedto deal
with the problem of secure outsourcing computation as well. Accordingly, an outsourced
verification protocol, including the transformation algorithm for outsourced verification
Transfer, the outsourced verifying algorithm Verifyoutand the verifying algorithm
Verify, replaces the original verifying algorithm in OABS definition.
