基于密文操作的云平台数据保护技术研究
Research on cloud platform data protection technology based on ciphertext operation
摘要
Abstract
In view of the current encryption algorithm can′t solve the equilibrium problem between data practicality and da⁃ta security in cloud storage platform,the algorithm of integer homomorphic encryption with identifiable permission (HEIP) is proposed. The security,time complexity and algorithm efficiency of this scheme are analyzed. On the basis of the integer homo⁃morphic encryption scheme,and in combination with the actual cloud storage application situation,the homomorphic encryption cloud storage system with secondary agent was designed,and the realization method of key modules are given. Finally,the effec⁃tiveness of the cloud storage platform,safety of the two⁃stage decryption architecture and correctness of the homomorphic calcula⁃tion mode were verified by experiments.关键词
