چکیده (انگلیسی):

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.
