Security has been considered as an important issue in processor design. Most of the existing mechanisms address security and integrity issues caused by untrusted main memory in single-core systems. In this paper, the authors propose a Secure Chip Multi-Processor architecture (SecCMP) to handle security related problems such as key protection and core authentication in multi-core systems. Threshold secret sharing scheme is employed to protect critical keys because secret sharing is a distributed security scheme that matches the nature of multi-core systems.
