A cloud data integrity verification algorithm based on homomorphic hash function

Zhou Rui Wang

Cloud storage has become a trend for future storage development, but it also poses new security challenges, such as cloud service providers may tamper with data for some reason. To ensure the integrity of cloud data, a cloud data integrity checking algorithm based on homomorphic hash function is proposed. Under the audit of trusted third party, the algorithm verifies the integrity of cloud data by aggregating multiple RSA signatures. In order not to disclose user data information, the same-state linear authentication and random masking technology are adopted to realize privacy protection. The analysis results show that this algorithm can not only effectively resist the malicious attack of the server, but also support the data update, compared with the existing audit algorithm, the algorithm can reduce the computational cost in the verification process, and reduce the traffic volume in the batch audit, so as to improve the verification efficiency.
