Uniting Hardware Security From Lightweight PUFs to Efficient Post-Quantum Cryptography

This talk highlights hardware security research focusing on Physical Unclonable Functions (PUFs) and Post-Quantum Cryptography (PQC) accelerators, as well as their integration. For lightweight security, PUFs are implemented on FPGA, ASIC, and RRAM platforms to provide low-cost, unclonable device identities. Key contributions include ultra-low-power ASIC PUFs, RRAM PUFs resistant to machine learning and physical attacks, and PUF-based authentication protocols. For efficient hardware accelerators for lattice-based PQC algorithms, NTT cores, Kyber, and Dilithium accelerators are studied. A multi-protocol PQC chip taped out in 28 nm. Side-channel attack countermeasures are also implemented to enhance security. Future directions will also be discussed.
