Abstract: With the development of information science and technology, trusted computing, as the key technique of cyberspace security, it has become the focus of international cyberspace combat. China is promoting its application in various fields. Trusted software base (TSB), which lies in the kernel of trusted computing architecture, protect upperlevel application and manage lowerlevel trusted platform control module (TPCM) at the same time. In this paper, we describe the function structure, working procedure, supportability and interactive interfaces of TSB by core technology research of trusted software, and introduce its successful application in practical projects. As a whole, TSB serve as the solid foundation of trusted computing technology which can promote its further development.

Key words: trusted computing, trusted software base, trusted platform control module, cyberspace security, cryptography
