Design and Implementation of Security Management Architecture of Special SoC

Aiming at the security related questions of special SoC chip, this paper has given the threat model and distribute model of the chip firstly. Then, we have divided the assets of the chip into different security levels. We have proposed the design of the chip´s working status, together with the design and implementation of the constraint conditions of the transitions between different working status. Moreover, we have given the secure working flow of the chip. The security analyses indicates that our chip can satisfy the practical requirements of confidentiality, integrity and authenticity.
