Trust Cloud Computing Platform Based On TNC

Data security and privacy protection are generally considered two important basic services of cloud computing. So far, however, there is no means to prove the integrity and confidentiality of the data and applications, It brings the issue of trust between cloud service providers, which will become one of the biggest obstacle to hinder the development of cloud computing.The combination of trusted computing technology and cloud computing is one of the methods to solve this problem of trust. The objective of Trusted Computing is to enhance the credibility of the computer system. Its included remote attestation, trusted network connection technology can be effectively applied to the cloud computing platform to address the issue of trust between cloud service providers and customers.This paper systematically expounded the architecture of cloud computing platform after the introduction of the Trusted Network Connection. In this process, we found that there is a loophole in the Trusted Network Connection, which is platform spoofing attack. This attack will lead to the failure of the platform authentication and platform integrity check error. This article uses the method of adding user attributes in the integrity of the assessment process to solve the platform spoofing attack. And the effectiveness of the method is proved by experiments.After the introduction of the Trusted Network Connect to the cloud computing platform, it can effectively solve the security problems caused by fraudulent use of legitimate user identities attack, to protect the legitimate user’s data security, but also to protect the security of the cloud computing platform.
