  • 摘要:Cloud storage is considered to be the most critical factor in decision making for users as it largely scales down the infrastructure in terms of size, cost and design. Considering factors such as local storage cost, maintenance a single server model can support multiple users on a needed basis. This raises concerns for integrity verification i.e., assuring the correctness of the data stored available in cloud. The proposed auditing algorithm suggests and investigates digital signature for integrity verification. A Modified Version of Elliptic curve digital Signature Algorithm is proposed for auditing the task. The main focus of this study is to address problems such as privacy preserving, public auditing. In addition, the performance of the auditing task is optimized. Data dynamics have been modeled through various data operations such as block insertion, deletion and block modification. Extensive theoretical and experimental analysis presented in the paper shows that security, performance of the proposed algorithm are improved in terms of verification time of the auditing process.
