"Public Cloud Data Auditing Revisited: Removing the Tradeoff Between Pr" by Willy Susilo, Yannan Li et al.
Public cloud data auditing allows any third party to check the integrity of data stored on untrusted cloud servers without retrieving the data. The challenge is how to audit the proof of storage with efficient communications. In ACM CCS 2007, Ateniese et al. described the first practical public cloud data auditing scheme based on RSA, in which the proof of storage consists of one RSA element and one hash value and the storage cost for generating the proof can be as short as 1% of the stored file...
