Abstract—With the development of attack technique, new security problems have become more and more popular, traditional security means such as: firewall, IDS and so on expose to be limited, there is a basic consensus that solving the problem of information security is from terminal. Based on the deep analysis of the relation between the concept of “security” and “trusted” in computer system, this paper proposes a novel secure terminal system Based on trusted hardware: U-Key. It describes the architecture design of the whole secure system and analyses the important security function implemented. Moreover, the main performance overhead of system is analyzed. This paper gives illumination on how to take advantage of trusted hardware to enhance the security of terminal system.

Index Terms—Terminal, U-Key, trusted computing, security function, security policy, security objective.
