可信平台模块在云计算中的应用

Application of the Trusted Platform Module in Cloud Computing

该文分析云计算的发展现状,以及用户的重要数据在云环境下的虚拟数据中心存储过程中所产生的一系列安全问题。针对数据存储过程中所产生的安全问题,我们在云计算中引入了可信平台模块、虚拟化技术以及二者结合的虚拟可信平台模块,并介绍了可信平台模块的基本功能,主机平台上可信链的建立,以及SHA-1算法在云计算中的应用。

This paper analyzes the current development of cloud computing,as well as a series of security problems generated by the storage process of the user＇s important data in the virtual datacenter of the cloud environment.According to those security problems,we introduce the Trusted Platform Module,the Platform Virtualization Technology as well as the combination of both virtual trusted platform module,and describes the basic functions of the Trusted Platform Module,the establishment of trusted chain in the host platform,as well as the application of security harsh algorithm（SHA-1） in cloud computing.
