基于云计算环境的平台可信度认证问题研究

摘要

为了搭建可信的云计算环境，云平台和用户平台之间需要进行相互认证。鉴于云环境的基本特征，提出一种基于云环境的平台可信度认证模型（CCEBA）。该模型引用可信计算平台远程证明的思想，将改进的基于模块和组件属性的可信证明方案应用于云平台的可信度认证中。用户平台认证则采用改进的基于系统行为的可信证明方案。实验结果表明，该认证模型有效地提高了云平台和用户平台之间认证的可信度，并且提高了远程证明的效率，从而搭建了可信的云计算环境。%In order to build a trusted cloud computing environment,there is the need to mutually authenticate each other between cloud platform and users’platform.In view of the basic characteristics of cloud environment,in this paper we put forward a cloud computing environment-based platform credibility authentication model (CCEBA).The model cites the idea of remote attestation of trusted computing platform,and applies the improved trusted attestation scheme based on the properties of modules and components to the credibility authentication of cloud platform.The authentication of user platform adopts the improved system behaviour-based trusted attestation scheme. Experimental results show that the authentication model increases the credibility of authentication between cloud platform and user platform effectively,and improves the efficiency of remote attestation,so that builds a trusted cloud computing environment.
