A secure remote data integrity checking cloud storage system from threshold encryption

The confidentiality and integrity are the most important issues in cloud storage system. We address the privacy issue of decentralized cloud storage system using threshold cryptography. Once the user uploads his data and deletes the local copy, he might lost the full control of the data. The major challenges of designing this cloud storage system are to provide a better privacy guarantee and ensure the integrity of data at untrusted servers in distributed cloud storage system. To achieve this goal, we propose a threshold encryption scheme and integrate it with a secure decentralized erasure code to form a secure cloud storage system, where the user generates a secret parameter participated in system encryption and decryption of plaintext blocks in the combine process. So our systems can prevent cloud storage servers from modifying data by providing remote data check and meets the requirements of data robustness, confidentiality and integrity.

Implementing Remote Data Integrity Checking Protocol for Secured Storage Services with Data Dynamics and Public Verifiability In Cloud Computing

Cloud computing aims to enable end-users to easily create and use software without a need to worry about the technical implementations and nitty-gritties such as the software's physical hosting location, hardware specifications, efficiency of data processing. Recently many works focus on providing data dynamics and/or public verifiability to the protocols checking the remote integrity with the help of third party verifiers. In this paper, Sebe et al.'s protocol is adapted to support public verifiability and data dynamics without the help of a third party auditor. This design allows users to audit the cloud storage with very lightweight communication and computation cost. In addition, the auditing result not only ensures strong cloud storage correctness guarantee, but also simultaneously achieves fast data error localization, i.e., the identification of misbehaving server. The design further supports secure and efficient dynamic operations on outsourced data, including block modification, deletion, and append. Through a formal analysis, the correctness and security of the protocol is shown. The proposed scheme is highly efficient and resilient against the malicious data modification attack, server clouding attacks and failure.

A Privacy-Preserving Remote Data Integrity Checking Protocol with Data Dynamics and Public Verifiability

Remote data integrity checking is a crucial technology in cloud computing. Recently, many works focus on providing data dynamics and/or public verifiability to this type of protocols. Existing protocols can support both features with the help of a third-party auditor. In a previous work, Sebé et al. propose a remote data integrity checking protocol that supports data dynamics. In this paper, we adapt Sebé et al.'s protocol to support public verifiability. The proposed protocol supports public verifiability without help of a third-party auditor. In addition, the proposed protocol does not leak any private information to third-party verifiers. Through a formal analysis, we show the correctness and security of the protocol. After that, through theoretical analysis and experimental results, we demonstrate that the proposed protocol has a good performance.

A Time-Bound Ticket-Based Mutual Authentication Scheme for Cloud Computing

<p>Cloud computing is becoming popular quickly. In cloud computing, people store their important data in the cloud, which makes it important to ensure the data integrity and availability. Remote data integrity checking enables the client to perform data integrity verification without access to the complete file. This service brings convenience to clients, but degrades the server’s performance severely. Proper schemes must be designed to reduce the performance degradation.<br /> In this paper, a time-bound ticket-based mutual authentication scheme is proposed for solving this problem. The proposed authentication scheme achieves mutual authentication between the server and the client. The use of timebound tickets reduces the server’s processing overhead efficiently. The correspondence relationship between the digital ticket and the client’s smart card prevents user masquerade attack effectively. By security analysis, we show that the proposed scheme is resistant to masquerade attack, replay attack and password guessing attack. By performance analysis, we show that the proposed scheme has good efficiency. The proposed scheme is very suitable for cloud computing.</p>
