ePrint Report: RDS: FPGA Routing Delay Sensors for Effective Remote Power Analysis Attacks

David Spielmann, Ognjen Glamocanin, Mirjana Stojilovic

State-of-the-art sensors for measuring FPGA voltage fluctuations are time-to-digital converters (TDCs). They allow detecting voltage fluctuations in the order of a few nanoseconds. The key building component of a TDC is a delay line, typically implemented as a chain of fast carry propagation multiplexers. In FPGAs, the fast carry chains are constrained to dedicated logic and routing, and need to be …
