云计算环境下数据访问安全性研究

摘要

基于Internet的云计算数据访问安全是云计算安全的中心.本文介绍了云计算应用的基本概况及云计算发展遇到的关键问题,设计了基于MD5、SM2及SSF33算法和身份认证的PKI安全访问体系架构,并保证了基于此安全访问架构下的公开信道的数据访问安全.%Because the date access security is the center of the security of cloud computing This paper firsty analyzed and summarized the overview of cloud computing and furter analyzed the key problems in devecopment and designed the PKI safe access arch itectcre based on MD5,SM2,SSF33 and digital certificates.It ensures the date access security basecl on this architecture on internet.
