I build trust into hardware, so connected vehicles, IoT devices and quantum-era networks can prove who they are.
Visiting Researcher at
Two identical chips, two different fingerprints
A physical unclonable function (PUF) turns microscopic manufacturing differences into a response nobody can copy. Set a challenge, then ask two chips made from the same design. This demo runs a simulated arbiter PUF in your browser.
Challenge
Chip A
················
Chip B
················
Responses appear here. Bits where the chips disagree get a butter-yellow ring.
What I work on
See research projectsHardware identity with PUFs
Authentication rooted in silicon variation: SRAM, arbiter and MEMS-based PUFs, and protocols light enough for vehicles and sensors.
Blockchain consensus
Reputation-aware and proof-of-energy consensus for EV energy trading and tamper-evident IoT ledgers.
Quantum-era security
Fault-tolerant distributed quantum computing, post-quantum cryptography and quantum-aware distributed ledgers.
Vehicles, edge and robots
Fog computing for VANETs, collaborative autonomous driving and LoRa localization where GPS fails.

How a PUF works, from silicon variation to a login protocol
Physical unclonable functions turn manufacturing randomness into a fingerprint no one can copy. Here is how they are built, measured, made reliable and attacked, with simulations you can run.
