Abstract
Plenty of computing and storage resources in the cloud are provided for users with restricted computing and storage resources, which has attracted the attention of many researchers. A generic blockchain-based cloud data auditing scheme is proposed, which is compatible with any blockchains including the bitcoin blockchain. In the data integrity checking scheme, certificateless signature (CLS) can be used to verify the identity of users. Besides, the key exchange is utilized in the key generation, which can eliminate the security channel to achieve system robustness. Considering the real situation, the users who join the cloud storage system may be revoked for some reasons. Therefore after a user is revoked, it is necessary to detect the validity of the tags of the revoked user and update the tags on manner. The group manager (GM) of scheme updates the key of the non-revoked user with the number of revoked users.
