摘要

Cloud auditing is a significant technique for determining the security of data owners' data in cloud. However, multiple-replica places greater demands on cloud auditing, where not only the integrity of each data replica but also the number of replicas should be checked. Moreover, it is also significant to support dynamical updating for multiple-replica data. Therefore, how to achieve secure and effective multiple-replica dynamic data auditing is a cutting-edge issue for cloud auditing. Recently, an efficient multi-replica dynamic data auditing scheme (IEEE Transactions on Information Forensics & Security, DOI: 10.1109/TIFS.2014.2384391) was presented to address this issue. Unfortunately, there is a security defect in this protocol, as we demonstrate in this paper. Specifically, a dishonest cloud storage provider can store an aggregation of all data copies instead of each replica itself without being detected by an auditor. Accordingly, we suggest a solution to resolve the problem while preserving all the properties of the original protocol.
