基于云环境CPK认证的研究

Research on CPK authentication in cloud environment

从云计算的安全问题入手,引出了CPK认证系统和访问控制的概念,介绍了CPK认证的模式,通过分析比较CPK与PKI两种身份认证方法,探讨了CPK在云环境下的适用性,并对基于角色的访问控制模型作了详细的介绍,最后对基于角色的云平台访问控制构架的模型进行分析,提出了CPK认证方法与RBAC3访问控制模型相融合的方案。

This paper begins with the security problem of cloud computing, to draw forth the concepts of CPK authentication system and access control, and introduces the CPK authentication mode. By comparing the CPK and PKI authentication methods,the applicability of CPK in cloud environment is discussed, and the role-based access control model is introduced in detail. Finally,the model of role-based cloud platform access control architecture is analyzed and the scheme which fuses the CPK authentication method and RBAC3 access control model is put forward.
