I work in the Center for Future Architectures Research (C-FAR) at Michigan doing research in hardware security. I study robust on-chip run-time defenses against hardware trojans.

My Research

Recent work has demonstrated how a malicious engineer during design or manufacturing of a computer chip can insert a practically undetectable amount of additional logic that will provide them with a backdoor to any system using that chip. Since this designer is theoretically capable of modifying any component in the design, any defenses placed on-chip are equally susceptable to attack. I am developing on-chip defenses that allow us to leave a chip's design partially undefined at manufacture time at very low cost. By permuting the design, we prevent the attacker from ever knowing what to attack while hiding critical modules in with on-chip checkers.

Pitfalls and Tradeoffs in Simultaneous, On-Chip FPGA Delay Measurement

On-chip tests can provide full knowledge of the path delays between components on an FPGA. We discovered that the testing circuitry itself introduced measurable error while providing opportunities for parallel measurement.
