This paper presents a system in the trusted platform called Trusted Terminal System (TTS). Based on Trusted Cryptography Module (TCM), TTS establishes an comprehensive protection system of the terminal host via several key technologies such as trusted boot, kernel measurement and integrity report. Also, TTS sends the integrity status of terminal to the Trusted Terminal Attestation Server (TTAS) by remote attestation technology for the purpose of ensuring the terminal within a trusted environment. The paper illustrates the fundamental of the TTS, and also the key technologies and implementation method based on it. Finally, the paper describes the construction technology of TTS based on the TCM and analyzes its performance.
