Tamper Proofing Commodity Hardware & other Applications
summary
Introduces Enclosure-PUF, a physical unclonable-function technology that measures electromagnetic wave propagation inside whole devices to verify authenticity, integrity, and detect tampering of commodity hardware like off-the-shelf PCs and ATMs. Describes deriving cryptographic keys from the environment’s unclonable physical disorder, testing the technique on complex systems with moving parts (fans, HDDs) and harsh conditions, and using machine learning to handle practical limitations and attacks such as drilling/spudding.
