  4. Abstract:
  5. Data sharing is considered as a favorite service provided by cloud storage servers in which the stored data is shared among a group of users. However, auditing such shared data is a big security issue for cloud users. In this paper, we propose an ID-Based public shared data integrity auditing scheme, in which all the group users are able to update, delete or insert new blocks into the shared data. Besides, the cloud server can revoke a misbehaving user with a minimum overhead. The scheme is secure against an untrusted cloud server and also preserves data privacy against the public verifier. Furthermore, overhead analysis shows the efficiency of proposed scheme in comparison to the existing well-known schemes. © 2020 IEEE
