Routing Aware and Runtime Detection for Infected Network-on-Chip Routers
Network-on-Chip (NoC) architecture is the communication heart of the processing cores in Multiprocessors Systemon-Chip (MPSoC), where messages are routed from a source to a destination through intermediate nodes. Therefore, NoC has become a target to security attacks. By experiencing outsourcing design, NoC can be infected with a malicious Hardware Trojans (HTs) which potentially degrade the system performance or leave a backdoor for secret key leaking. In this paper, we propose a HT model that applies a denial of service attack by misrouting the packets, which causes deadlock and consequently degrading the NoC performance. We present a secure routing algorithm that provides a runtime HT detection and avoiding scheme. Results show that our proposed model has negligible overhead in area and power, 0.4% and 0.6%, respectively.
