• Fully homomorphic encryption
• Cloud server provider
• Data owner
• Public verification
• Replicated data possession

Nowadays, many organizations outsource their data to remote cloud servers. In order to increase the availability of data, the data owners store their data replicas on multiple servers. In this paper, we propose a dynamic replicated data possession checking scheme that has three characteristics: the data owner uses fully homomorphic encryption algorithm to generate multiple copies; the scheme supports data block dynamic operation; our scheme can identify the corrupted data block. Finally, security analysis and experimental results show that our scheme can resist forge, replace and replay attack, and perform better than some other related scheme published recently.
