Silicon Reverb (2024)
A Year Later: Reflections on Low-Cost Hardware Security and Beyond It’s hard to believe it has already been a year since I presented and published my paper “Silicon Reverb: Non-Invasive Low-Cost Solution for Detecting Hardware Trojans” at IEEE NAECON 2024 . The paper presented a scalable, accessible methodology for non-invasive trojan detection in FPGAs using low-cost tools like the LibreVNA and Digilent Digital Discovery . What started as a class project in replicating the work of Silicon Echoes , a groundbreaking approach to frequency-selective impedance analysis for Trojan detection, has since evolved into a broader exploration of how impedance-based methods can be applied beyond just hardware security. How It Started: The Influence of Silicon Echoes When I first read the Silicon Echoes paper by Mosavirik et al., I was struck by how elegantly it combined RF analysis with hardware security. Their use of a Keysight PNA and NEWAE CW305 FPGA Target Boar...
