Data integrity verification protocol in cloud storage system
Lanxiang Chen · Journal of Computer Applications · 2012
In the cloud storage network,the security and integrity of data are the major concerns of clients.Taking full consideration of the security requirements for cloud storage network,a new Cloud Storage-Data Integrity Verification(CS-DIV) protocol was proposed.The clients uploaded files and tags to the servers and then did random check;the servers returned proofs and the clients judged the result.This protocol could not only ensure the integrity of data in the cloud storage effectively,but also resist the cheat from the un-trusted servers and the attack from the malicious clients,and then improved the reliability and stability of the whole cloud storage system.The simulation experimental results show that the proposed protocol realizes the protection of data integrity at low cost of storage,communication and delay.
