Address Obfuscation to Protect against Hardware Trojans in Network-on-Chips

In modern computing, which relies on the interconnection of networks used in many/multi-core systems, any system can be critically subverted if is compromised. This done a multitude ways, but threat hardware Trojan (HT) being injected into particularly prevalent due to increase third-party manufacturers for system-on-chip (SoC) designs. With local injection an HT SoC, adversary gain access information about applications running by revealing specific communications and network-on-chip (NoC) as whole. heavily compromises gives attacker, lead more tailored, compromising attacks. this paper, we demonstrate that exploits communication patterns inside SoC reveal are NoC with multi/many-core processors. performed leaking packet counts, after attacker then uses machine learning techniques identify processors, We also propose LUT-based obfuscation technique limit available Trojan. Our results indicate method reduce accuracy attack from 99% <8% systems.
