| Abstract: | 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 noninterference-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 dynamic CoT, and analyzed the remote attestation technology of chain of trust, and presented the CoT systems in cloud computing environment, 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. |
