英文摘要：

In order to improve the security when users access to cloud computing, constructed of trusted authentication model using remote attestation, and proposed a trusted authentication cloud security protocol. The proposed protocol realizes a two-factor authentication of identity and platform for user and cloud server. It shows that the protocol with higher security and efficiency, as well as satisfies the privacy protection requirement of the platform configuration in cloud environment.
