The unique parasitic electromagnetic (EM) radiation emanated from Integrated Circuits (IC) has been used for IC fingerprinting. However, currently available tool is costly and IC fingerprinting is performed just one-time offline during the qualification in IC life-cycle. Due to untrusted supply chain of IC design and fabrication, it is important to develop techniques that can provide real-time IC integrity monitoring and assurance not just at the initial deployment of IC but during the entire IC life-cycle. To address this issue, in this project, we plan to develop on-chip EM sensors by integrating nano-antenna arrays on IC for continuous monitoring of IC during its entire life-cycle. We will benchmark the on-chip nano-antenna array EM sensors with commercial EM probes for measuring the EM spectrum from Complementary Metal Oxide Semiconductor (CMOS) ICs. Finally, we will use this approach to predict the integrity and aging of CMOS IC over the entire life-cycle for trust and assurance. Once this test-bed is created then our on-chip EM sensor can also be used to detect any EM side-channel attack or Trojan, and implement event-driven obfuscations or re-training of reconfigurable AI hardware (in case used for AI hardware integrity monitoring) which will be explored in future.
