信任链是实施可信系统的关键技术之一，本文从信任链理论和应用系统出发，介绍了研究信任链理论的典型模型及近年来的研究进展，包括基于无干扰理论的信任链传递模型和基于组合安全理论的信任链模型，详细阐述了这两种信任链理论模型的优势和不足。介绍了基于静态信任根和动态信任根的信任链应用系统的研究状况，介绍了信任链远程证明技术，介绍了云计算环境下的信任链应用系统，对信任链应用系统存在的安全缺陷以及一致性和安全性测评方法进行了分析论述，并展望了该领域未来的发展趋势。

Chain of trust (CoT) is one of the key technologies for constructing trusted system .As viewed from theories and application systems of CoT ,this paper introduced several representative models and the latest investigations including noninterfer-ence-based CoT theory and composition security-based CoT theory firstly .Afterward ,this paper expatiated advantage and shortage of two CoT theories in detail .Secondly ,this paper introduced the development of application systems comprising static CoT and dy-namic CoT ,and analyzed the remote attestation technology of chain of trust ,and presented the CoT systems in cloud computing en-vironment ,and analyzed the security deficiency of those systems ,and then discussed the conformance testing and security evaluation for CoT application system .Finally ,this paper put forward the research and development trend for CoT .
