Attack Mitigation of Hardware Trojans for Thermal Sensing via Micro-ring Resonator in Optical NoCs

As an emerging role in new-generation on-chip communication, optical networks-on-chip (ONoCs) provide ultra-high bandwidth, low latency, and power dissipation for data transfers. However, the thermo-optic effects of photonic devices have a great impact on operating performance reliability ONoCs, where thermal-aware control with accurate measurements, e.g., thermal sensing, is typically applied to alleviate it. Besides, temperature-sensitive ONoCs are prone be attacked by hardware Trojans (HTs) covertly embedded counterfeit integrated circuits (ICs) from malicious third-party vendors, leading degradation, denial-of-service (DoS), or even permanent damages. In this article, we focus tampering snooping attacks during sensing via micro-ring resonator (MR) ONoCs. Based provided workflow attack model, new structure anti-HT module proposed verify protect obtained sensor its sampling electronic transmission processes. addition, present detection scheme based spiking neural networks (SNNs) implement classification network security statuses further high-level control. Evaluation results indicate that, less than 1% extra area tile, our approach can significantly enhance ONoC trivial costs up 8.73%, 5.32%, 6.14% average execution time, energy consumption, respectively.
