摘　　要：可信计算近年发展迅速,被认为是最有可能从根本上解决计算机系统安全问题的一种方案,不同于传统信息安全解决办法,它以新的思路即主动防御来解决计算机和网络系统的信息安全问题。信任根和信任链是可信计算的根本组成部分。介绍了可信计算及信任链的相关知识,介绍了信任根,可信认证机制。最后详细给出了基于PCI扩展ROM的可信计算之信任链部分链实现的可行方案。Trusted computing, which has been considered as the best method in resolving the security of computer system, has been developing very fast in recent years. It is a new measure that makes use of active defending to resolve security problem of computer and network system. Root of the trust and the system of trusted chain are the most important components of trusted computing. The trusted computing and the trusted chain system, as well as the device of root of trust, and the authentication mechanism of trusted computing are introduced. At last a feasible scheme of trusted chain system based on PCI extended ROM used to resolve part of chain is provided in detail.
