Secure Network-on-Chip Architectures for MPSoC: Overview and Challenges
Luka B. Daoud · 2018
Network-on-Chip (NOC) is the heart of data communication between processing cores in Multiprocessor-based Systems on Chip (MPSoC). Packets transferred via the NoC are exposed to snooping, which makes NoC-based systems vulnerable to security attacks. Additionally, Hardware Trojans (HTs) can be deployed in some of the NoC nodes to apply security threats of extracting sensitive information or degrading the system performance. In this paper, an overview of some security attacks in NoC-based systems and the countermeasure techniques giving prominence on malicious nodes are discussed. Work in progress for secure routing algorithms is also presented.
