Abstract:
This paper proposes two integrity verification schemes based on Schnorr Signature Scheme, which are
named Safety Integrity Verification Scheme (SIVS) and Efficient Integrity Verification Scheme (EIVS). In the two verification
schemes, for the userâ€™s each challenge, the cloud storage server chooses randomly the sets of file blocks and verification
blocks to generate response values, and the user uses the set of signatures to verify response values. That is to check whether
the cloud storage server preserves perfectly the userâ€™s file or not. SIVS gives double integrity verification guarantee to cloud
storage data. EIVS has more efficient verification guarantee in computational costs than SIVS. According to the different
needs of users, EIVS cooperates with SIVS to improve efficiency when checking the integrity of cloud storage data. Compared
with other schemes, at the same level of security, the two cooperative schemes get better integrity verification guarantee, and
pay lower computational costs.
