摘要Trusted computing is a new technology for building secure system in recent years. TCG (Trusted Computing Group) has drafted a series of specifications on trusted computer. More and more hardware and software have been developed by manufactures, and trusted computer shows many advantages to protcct information security. In the period of designing secure platform, TCG specifications arc analyzed and some deficiency is found in them. This paper presents the main idea of TCG specifications and gives some suggestions on three neglected problems: compatibility with old applications, security policy and mechanism of self recovery.
