Wireless Network-on-Chip Security Review: Attack Taxonomy, Implications, and Countermeasures

Abstract

Network-on-chip (NoC) is a critical on-chip communication framework that underpins high-performance multicore computing and network system architectures. Its adoption has become widespread due to the ongoing emergence of cutting-edge NoC technologies. However, the introduction of wireless interfaces has expanded potential vulnerabilities, impacting confidentiality, integrity, and system availability. While there is a growing body of research in NoC security, a comprehensive study of security threats in wireless NoC is lacking. Our article provides an extensive review of recent advancements and research in wireless NoC security. This encompasses examinations, summaries, comparative assessments, and the constraints of existing studies. We conclude by delineating future research directions in this crucial field.
