Physical Time-Lock Puzzles
Niloufar Sayadi, Chenglu Jin, Phuong Ha Nguyen +2
Traditional time-lock puzzles enforce delayed access to encrypted secrets by relying on inherently sequential computational steps. However, since software-based constructions impos…
Breaking XOR Arbiter PUFs with Chosen Challenge Attack
Niloufar Sayadi, Phuong Ha Nguyen, Marten van Dijk +1
The XOR Arbiter PUF was introduced as a strong PUF in 2007 and was broken in 2015 by a Machine Learning (ML) attack, which allows the underlying Arbiter PUFs to be modeled individu…
Secure Remote Attestation with Strong Key Insulation Guarantees
Deniz Gurevin, Chenglu Jin, Phuong Ha Nguyen +2
Recent years have witnessed a trend of secure processor design in both academia and industry. Secure processors with hardware-enforced isolation can be a solid foundation of cloud…
Intrinsically Reliable and Lightweight Physical Obfuscated Keys
Raihan Sayeed Khan, Nadim Kanan, Chenglu Jin +8
Physical Obfuscated Keys (POKs) allow tamper-resistant storage of random keys based on physical disorder. The output bits of current POK designs need to be first corrected due to m…
