Istanbul Technical University Institute of Science and Technology Reliability and Security of Arbiter Based Physical Unclonable Function

Information-Dense Nonlinear Photonic Physical Unclonable Function

We present a comprehensive investigation into the complexity of a new private key storage apparatus: a novel silicon photonic physical unclonable function (PUF) based on ultrafast nonlinear optical interactions in a chaotic silicon microcavity that is both unclonable and impossible to emulate. This device provides remarkable improvements to total information content (raw cryptographic material)...

A Stateless Cryptographically-Secure Physical Unclonable Function

We present the first stateless construction of a cryptographically-secure Physical Unclonable Function. Our construct requires no non-volatile (permanent) storage, secure or otherwise, and its computational security can be clearly reduced to the hardness of Learning Parity with Noise (LPN) in the random oracle model. The construction is “stateless,” because there is no information stored betwee...

Barrel Shifter Physical Unclonable Function Based Encryption

Physical Unclonable Functions (PUFs) are circuits designed to extract physical randomness from the underlying circuit. This randomness depends on the manufacturing process. It differs for each device enabling chip-level authentication and key generation [1] applications. We present a protocol utilizing a PUF for secure data transmission. Parties each have a PUF used for encryption and decryptio...

SD-PUF: Spliced Digital Physical Unclonable Function

Digital circuit physical unclonable function (PUF) have been attracting attentions for the merits of resilience to the environmental and operational variations that analog PUFs suffer from. Existing state-ofthe-art digital circuit PUFs, however, are either hybrid of analog-digital circuits which are still under the shadow of vulnerability, or impractical for real-world applications. In this wor...
