As chip multiprocessors (CMPs) are becoming more susceptible to process variation, crosstalk, and hard and soft errors, emerging threats from rogue employees in a compromised foundry are creating new vulnerabilities that could undermine the integrity of our chips with malicious alterations. As the Network-on-Chip (NoC) is a focal point of sensitive data transfer and critical device coordination, there is an urgent demand for secure and reliable communication. In this paper we propose Secure Model Checkers (SMCs), a real-time solution for control logic verification and functional correctness in the micro-architecture to detect Hardware Trojan (HT) induced denial-of-service attacks and improve reliability. In our evaluation, we show that SMCs provides significant security enhancements in real-time with only 1.5% power and 1.1% area overhead penalty in the micro-architecture.
