Cloud Data Sharing With Public Integrity and User Revocation

Abstract

The overview of the cloud computing makes storage outsourcing become a growing fashion, which promotes the secure remote data auditing a warm subject matter that regarded in the research literature. Recently some research considered the hassle of comfortable and efficient public data integrity auditing for shared dynamic data. However, those schemes are still not relaxed in opposition to the collusion of cloud storage server and revoked organization users all through user revocation in realistic cloud storage device. In this paper, we determine out the collusion attack in the exiting scheme and provide an efficient public integrity auditing scheme with at ease group user cancellation based totally on vector commitment and verifier-nearby revocation organization signature. We design a concrete scheme based at the scheme definition. Our scheme preserving the public checking and efficient user revocation and also a few quality residences, such as confidently, performance, countability and traceability of secure group user revocation. Finally, the security and investigational analysis show that in comparison with its relevant schemes our scheme is likewise comfortable and efficient.
