Abstract:

Almost traditional remote data integrity checking (RDIC) schemes are suffering from the issue of high key management cost, because they rely on the expensive public key infrastructure (PKI). According to this phenomenon, this paper proposed an identity-based cloud storage audit scheme. Merkle Hash Tree (MHT) technology is used to realize the dynamic update of users data. It is proved that this scheme is safe and feasible through the scheme analysis. It is proved that this scheme has a good application prospect by the construction of cloud medical data management model.

Key words: cloud storage, RDIC, identity-based cryptography, dynamic operation
