云计算环境下的数据隐私保护与安全管理措施分析与优化

Analysis and optimization of data privacy protection and security management measures in the cloud computing environment

在云计算环境中,较为常用的加密方式为对称密钥与非对称密钥加密方式,但是此种加密算法的安全性难以满足现阶段数据隐私保护的需求。针对此种情况,文章对其安全性进行了优化研究,通过哈达玛矩阵来完成矩阵的替换,将分支数扩展至9,在一定程度上提升了AES加密算法的扩展性,并通过仿真试验验证了扩展性对算法的影响。通过对比发现,优化后的加密算法安全性相对优良。

In the cloud computing environment,the more commonly used encryption methods are symmetric key and asymmetric key encryption methods,and the security of this encryption algorithm is difficult to meet the needs of data privacy number protection at the present stage.In view of this situation,the research optimizes the security,replaces the matrix by Hadama matrix,expands the number of branches to 9,which improves the scalability of AES encryption algorithm to a certain extent,and verifies the influence of scalability on the algorithm through simulation test.Through comparison,it is found that the optimized encryption algorithm is relatively good in security.
