基于TPM的云计算平台双向认证方案

为了解决云计算服务环境中用户和云服务器之间的双向认证问题，提出一种基于可信平台模块的云计算平台双向认证方案。将可信计算技术和传统的智能卡口令认证方法相结合应用于云计算服务平台，实现云计算中双方身份的认证，协商生成会话密钥，同时对云服务器的平台可信状况进行了验证。实验分析表明，该方案可以抵抗常见的各种攻击，安全性较高。计算时间复杂度在云计算服务中能够满足要求。

Mutual authentication scheme based on the TPM cloud computing platform

A mutual authentication scheme based on the TPM cloud computing platform was proposed to solve the problem of mutual authentication between user and cloud computing server.Trusted computing technology and traditional smart card password method were used in cloud computing service platform.The scheme completed the authentication of both sides in cloud computing,generated the session key according consulting,at the same time,verified the credibility of cloud service platform.Experiment analysis shows that our scheme can resist various kinds of possible attacks,so it is therefore more secure than other schemes.And the computing time meet the requirements of cloud computing environment.
