System Design of a Trusted SoC and Detailed Analysis of its Secure State Transitions

According to the relevant criterion and principle for designing and evaluating various trusted computing chips, we have proposed a new trusted SoC chip, and have given the implementation of its basic functional modules. In detail, we have discussed the design of the trusted SoC security architecture and the main module functional modules such as microprocessor, cryptographic function module, security management module, input/output interface, along with the most important memory management unit. Moreover, we have discussed reliability of relevant parameters and transfer strategy for trusted root in chip development and application, together with the simulation and validation of corresponding functions. At last, we point out that one of the most important further research directions is the trusted measurement of dynamic data and software running in security environment.
