PP Unified Testing and Security Framework for Wireless Network-on-Chip Enabled Multi-Core Chips ABHISHEK VASHIST, Rochester Institute of Technology, USA ANDREW KEATS, Rochester Institute of Technology, USA SAI MANOJ PUDUKOTAI DINAKARRAO, George Mason University, USA AMLAN GANGULY, Rochester Institute of Technology, USA On-chip wireless interconnects have been demonstrated to improve the performance and energy consumption of data communication in Network-on-Chips (NoCs). However, the wireless interfaces (WIs) can be defective, rendering these broken links severely afect the performance. This makes manufacturing test of the WIs critical. While analog testing of the transceivers is possible, such methodologies are impractical in a Wireless NoC (WiNoC) due to large overheads. In addition to testing, security is another prominent challenge in WiNoCs, as the security breach can happen due to embedded hardware Trojans or through external attacker exploiting the wireless medium. The typical security measures used in general wireless networks are not practical in a WiNoC due to unique network architectures and performance requirements of such a system. However, both testing and security defense can potentially leverage a basic monitoring framework which, can detect malfunctions or anomalies. Based on this idea, we propose a unifed architecture for testing and attack detection and protection of on-chip wireless interconnects. We adopt a Built-In-Self Test (BIST) methodology to enable online monitoring of the wireless interconnects which can also be reused for monitoring the security threats. We focus on manufacturing defects of the WIs for testing and persistent jamming attack for the security measures, as this kind of attack is most likely on wireless communication systems. The BIST methodology is capable of detecting faults in the wireless links with a low aliasing probability of 2.32 × 10 -10 . Additionally, the proposed unifed architecture is able to detect the persistent jamming with an accuracy of 99.87% and sufer < 3% communication bandwidth degradation even in the presence of attacks from either internal or external sources.
