HOMOMORPHIC AUTHENTICABLE RING SIGNATURE MECHANISM FOR PUBLIC AUDITING ON SHA...Journal For Research
The document proposes a privacy-preserving mechanism called Oruta that allows a third-party auditor (TPA) to publicly audit the integrity of shared data stored in the cloud while preserving the identity privacy of data signers. Oruta utilizes ring signatures to construct homomorphic authenticators so the TPA can verify data integrity without retrieving the entire file or learning the identity of the signer on each data block. Oruta also supports batch auditing of multiple files and dynamic operations on shared data through the use of index hash tables. The mechanism aims to address privacy issues in auditing shared cloud data that could reveal the identities of valuable targets like particular users or special data blocks.
Oruta proposes the first privacy-preserving mechanism for public auditing of shared data stored in the cloud. It exploits ring signatures to compute verification information needed to audit integrity without revealing signer identity. The third party auditor can verify integrity of shared data without retrieving the entire file, while keeping private which user signed each block. Existing methods do not consider privacy for shared data or dynamic groups. Oruta aims to efficiently audit integrity for static groups while preserving identity privacy.

Shared Authority Based Privacy-preserving Authentication Protocol in Cloud Co...Migrant Systems
The document proposes a shared authority based privacy-preserving authentication protocol (SAPA) for cloud computing. SAPA addresses the privacy issue that arises when a user challenges a cloud server to request access to another user's data, as the request itself could reveal private information. SAPA uses anonymous access request matching and attribute-based access control to determine if two users' access requests are mutually compatible without revealing either user's private access desires. It also employs proxy re-encryption so the cloud server can provide temporary shared access between authorized users. The protocol aims to simultaneously achieve data access control, authority sharing between compatible users, and protection of users' privacy during the access request process.

Privacy preserving delegated access control in public clouds
Current approaches to enforce fine-grained access control on confidential data hosted in the cloud are based on fine-grained encryption of the data. Under such approaches, data owners are in charge of encrypting the data before uploading them on the cloud and re-encrypting the data whenever user credentials or authorization policies change. Data owners thus incur high communication and computation costs.
This document outlines a project to develop and implement an access control mechanism for outsourced data on the cloud. The project has four modules: a supporting application, service development, encryption/decryption, and role-based access. It discusses key terms like access control, access control models, outsourced data, and cloud computing. The system works by allowing a data owner to encrypt and outsource data to the cloud, which then processes and forwards the data to authorized users based on an agreed access policy.
This document summarizes a research paper that proposes a public auditing scheme for regenerating-code-based cloud storage. The scheme introduces a proxy that can regenerate authenticators on behalf of data owners to solve issues when authenticators fail in the absence of owners. It also designs a novel public verifiable authenticator generated using keys that can be regenerated using partial keys. Extensive analysis shows the scheme is provably secure and efficient enough to integrate into regenerating-code-based cloud storage.

The document proposes a secure multi-owner data sharing scheme called Mona for dynamic groups in the cloud. Mona allows any user in a group to anonymously share data with others in the cloud using group signatures and dynamic broadcast encryption. It aims to address challenges with existing schemes that have complexities increasing linearly with the number of owners and revoked users. The proposed Mona scheme achieves independent storage overhead and encryption costs from the number of revoked users and supports dynamic groups where new users can access previous files without owners.
Privacy preserving delegated access control in public cloudAswathy Rajan
This document summarizes a research paper that proposes a new approach called two layer encryption (TLE) to enforce fine-grained access control on confidential data stored in public clouds. The key aspects are:
1) TLE uses two layers of encryption - the data owner performs coarse-grained encryption and the cloud performs fine-grained encryption on top based on access control policies provided by the owner.
2) A challenging problem is how to decompose access control policies for the two layer encryption to work while minimizing what the owner manages and ensuring data confidentiality. The paper shows this is an NP-complete problem.
3) The paper proposes optimization algorithms to find near optimal decompositions and evaluates TLE

831 panda public-auditing-for-shared-data-with-efficient-user-revocation-in-t...Raja Ram
This document proposes a public auditing mechanism called Panda for ensuring integrity of shared data with efficient user revocation in the cloud. Existing public auditing mechanisms require re-signing of data blocks by existing users when a user is revoked, which is inefficient. Panda utilizes proxy re-signatures to allow the cloud to re-sign blocks on behalf of existing users during revocation, avoiding the need for existing users to download and re-sign blocks. A public verifier can still audit integrity of shared data without retrieving the entire data, even if parts have been re-signed by the cloud. Panda improves efficiency of user revocation and reduces computation/communication costs for existing users.
Integrity Privacy to Public Auditing for Shared Data in Cloud ComputingIJERA Editor
In cloud computing, many mechanisms have been proposed to allow not only a data owner itself but also a public verifier to efficiently perform integrity checking without downloading the entire data from the cloud, which is referred to as public auditing . In these mechanisms, data is divided into many small blocks, where each block is independently signed by the owner; and a random combination of all the blocks instead of the whole data is retrieved during integrity checking .However, public auditing for such shared data— while preserving identity privacy — remains to be an open challenge. Here, we only consider how to audit the integrity of shared data in the cloud with static groups. It means the group is pre-defined before shared data is created in the cloud and the membership of users in the group is not changed during data sharing. The original user is responsible for deciding who is able to share her data before outsourcing data to the cloud. Another interesting problem is how to audit the integrity of shared data in the cloud with dynamic groups — a new user can be added into the group and an existing group member can be revoked during data sharing.

This document proposes a new privacy-preserving public auditing mechanism called Oruta that allows public auditors to efficiently verify the integrity of shared data stored in the cloud without downloading the entire file. Existing public auditing mechanisms reveal the identity of the signer on each data block to the public auditor, compromising privacy. Oruta utilizes ring signatures to construct verification metadata such that the public auditor can verify data integrity without learning the identity of the signer. It also supports batch auditing to verify multiple tasks simultaneously, improving efficiency. The mechanism aims to achieve public auditing, correctness, unforgeability, and preserve the identity privacy of data signers from public auditors.
This document summarizes a research paper that proposes a new public auditing mechanism called Panda for verifying the integrity of shared data in the cloud with efficient user revocation. Panda utilizes proxy re-signatures to allow the cloud to re-sign data blocks on behalf of existing users when a user is revoked, avoiding the need for existing users to download and re-sign blocks themselves. The proposed mechanism supports public auditing, where a third party can verify data integrity without retrieving the entire dataset from the cloud. It also enables batch auditing to verify multiple audit tasks simultaneously in a scalable manner. The system aims to improve the efficiency of user revocation for securely sharing data in cloud computing environments.
With cloud storage services, it is commonplace for data to be not only stored in the cloud, but also shared across multiple users. However, public auditing for such shared data — while preserving identity privacy — remains to be an open challenge. In this paper, we propose the first privacy-preserving mechanism that allows public auditing on shared data stored in the cloud. In particular, we exploit ring signatures to compute the verification information needed to audit the integrity of shared data. With our mechanism, the identity of the signer on each block in shared data is kept private from a third party auditor (TPA), who is still able to publicly verify the integrity of shared data without retrieving the entire file. Our experimental results demonstrate the effectiveness and efficiency of our proposed mechanism when auditing shared data.
This document proposes a system for privacy-preserving public auditing of data stored in the cloud.

The system architecture incorporates modules for privacy-preserving auditing, batch auditing, and data dynamics operations.
This document discusses public auditing mechanisms for verifying the integrity of data shared in the cloud. It begins with an introduction to public auditing and how early versions used homomorphic authenticators to check data integrity without retrieving the entire file. It then reviews the literature on public auditing, including proposals that introduced techniques like provable data possession (PDP), Merkle hash trees, and using a third party auditor. The document describes the system architecture involving cloud servers, users sharing data, and public verifiers. It explains mechanisms like PDP using challenge-response protocols and later extensions that supported dynamic operations and user revocation. The goal of these mechanisms is to allow remote verification of stored data integrity without downloading entire files.

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

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

oruta privacy-preserving public auditing for shared data in the cloud
1. Oruta Privacy-Preserving Public Auditing for Shared Data in the Cloud
Oruta Privacy-Preserving Public Auditing for Shared Data in the
Cloud
With cloud data services, it is commonplace for data to be not only stored in the cloud, but also
shared across multiple users. Unfortunately, the integrity of cloud data is subject to skepticism
due to the existence of hardware/software failures and human errors. Several mechanisms have
been designed to allow both data owners and public verifiers to efficiently audit cloud data
integrity without retrieving the entire data from the cloud server. However, public auditing on the
integrity of shared data with these existing mechanisms will inevitably reveal confidential
information—identity privacy—to public verifiers. In this paper, we propose a novel privacy-preserving
mechanism that supports public auditing on shared data stored in the cloud. In
particular, we exploit ring signatures to compute verification metadata needed to audit the
correctness of shared data. With our mechanism, the identity of the signer on each block in
shared data is kept private from public verifiers, who are able to efficiently verify shared data
integrity without retrieving the entire file. In addition, our mechanism is able to perform multiple
auditing tasks simultaneously instead of verifying them one by one. Our experimental results
demonstrate the effectiveness and efficiency of our mechanism when auditing shared data
integrity.
EXISTING SYSTEM:
Many mechanisms have been proposed to allow not only a data owner itself but also a
public verifier to efficiently perform integrity checking without downloading the entire
data from the cloud, which is referred to as public auditing . In these mechanisms, data is
divided into many small blocks, where each block is independently signed by the owner;
and a random combination of all the blocks instead of the whole data is retrieved during
integrity checking . A public verifier could be a data user (e.g., researcher) who would
like to utilize the owner’s data via the cloud or a third-party auditor (TPA) who can
provide expert integrity checking services.

2. Oruta Privacy-Preserving Public Auditing for Shared Data in the Cloud
Moving a step forward, Wang et al. designed an advanced auditing mechanism .so that
during public auditing on cloud data, the content of private data belonging to a personal
user is not disclosed to any public verifiers. Unfortunately, current public audit ing
solutions mentioned above only focus on personal data in the cloud .We believe that
sharing data among multiple users is perhaps one of the most engaging features that
motivates cloud storage. Therefore, it is also necessary to ensure the integrity of shared
data in the cloud is correct.
Existing public auditing mechanisms can actually be extended to verify shared data
integrity. However, a new significant privacy issue introduced in the case of shared data
with the use of existing mechanisms is the leakage of identity privacy to public verifiers.
DISADVANTAGES OF EXISTING SYSTEM:
1. Failing to preserve identity privacy on shared data during public auditing will reveal
significant confidential information to public verifiers.
2. Protect these confidential information is essential and critical to preserve identity privacy
from public verifiers during public auditing.
PROPOSED SYSTEM:
In this paper, to solve the above privacy issue on shared data, we propose Oruta, a novel
privacy-preserving public auditing mechanism.
More specifically, we utilize ring signatures to construct homomorphic authenticators in
Oruta, so that a public verifier is able to verify the integrity of shared data without
retrieving the entire data while the identity of the signer on each block in shared data is
kept private from the public verifier.
In addition, we further extend our mechanism to support batch auditing, which can
perform multiple auditing tasks simultaneously and improve the efficiency of verification
for multiple auditing tasks.
Meanwhile, Oruta is compatible with random masking, which has been utilized in
WWRL and can preserve data privacy from public verifiers. Moreover, we also leverage
