| Abstract | Wireless Network-on-Chip (WNoC) broadly adopts single channel for low overhead data transmission. Sharing of the channel among multiple wireless interfaces (WIs) is controlled by a channel access mechanism (CAM). Such CAM can be malfunctioned by a Hardware Trojan (HT) in a malicious WI or a rogue third party intellectual property (IP) core present on the same System-on-Chip (SoC). This may result in denial-of-service (DoS) or spoofing in WNoC leading to starvation of healthy WIs and under-utilization of wireless channel. Our work demonstrates possible threat model on CAM and proposes low overhead decentralized countermeasures for both DoS and spoofing attacks in WNoC. |
