Cloud platform computing security and integrity protection algorithm based on homomorphic encryption mechanism

Aiming at the risks of potential information leakage and data type variety of cloud platform, a cloud platform security protection algorithm based on homomorphic encryption mechanism was proposed. The encrypted users’ data were calculated with the as-proposed algorithm. In addition, the homomorphic encryption algorithm was used to protect the users’ detailed information; the data integrity privacy protection algorithm was used to accomplish the data integrity verification, and the RS coding algorithm was used to recover the original data when the data were damaged. The simulation test and experimental results based on Alibaba Cloud platform show that the as-proposed algorithm can realize the security protection of cloud platform data with less computational cost and recover the damaged data.
