Abstract: Trusted computing is an important application and research branch of the information security field, it is an effective mechanism to solve the current information security from the view of system. This paper describes the concept of trusted computing technology, and mainly analyzes the system of key management and the type of certificate in the trusted computing domain, and discusses the trusted platform module (TPM) and trusted computing platform (TCP). Based on the research of basic theory and realization method in the trusted computing domain,this paper summarizes the research progress of trusted computing and put forward the research direction of trusted computing.

Key words: trusted computing, key system, digital certificate, trusted platform module (TPM), trusted computing platform (TCP)
