Abstract

For the issues that the high communication overhead and dynamic data verification in the storage data integrity verification process on the cloud server, this paper proposed a dynamic data integrity verification and recovery scheme based on Merkle hash tree(MHT). Firstly, it constructed a new layered authentication data structure based on MHT, and organized each copy block of the data block into a copy sub-tree, thereby greatly reducing the communication overhead of multi-copy update verification. Then, it certified the server security index information authentication into the data validation, in order to avoid server attacks. Finally, it recovered the data by dichotomous discovery and Shamir's secret sharing mechanism when the data is corrupted. The experimental results show that this scheme can effectively reduce the computational and communication overhead and can support the dynamic operation of data in the verification process.
