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...
متن کاملTrapdoor Computational Fuzzy Extractors
We describe a method of cryptographically-secure key extraction from a noisy biometric source. The computational security of our method can be clearly argued through hardness of Learning Parity With Noise (LPN). We use a fuzzy commitment scheme so the extracted key is chosen by definition to have uniformly random bits. The biometric source is used as the noise term in the LPN problem. A key ide...

متن کاملPhysical Unclonable Functions and Secure Processors
As computing devices become ever more pervasive, two contradictory trends are appearing. On one hand computing elements are becoming small, disseminated and unsupervised. On the other hand, the cost of security breaches is increasing as we place more responsibility on the devices that surround us. The result of these trends is that physical attacks present an increasing risk that must be dealt ...
متن کاملReliable, Secure, Efficient Physical Unclonable Functions
A Physical Unclonable Function (PUF) is a die specific random function that can be used in a number of secure IC applications including die identification/authentication and key generation. At the core of a silicon PUF is a circuit (the PUF core) that generates random bits. These bits are like a silicon biometric, unique across dies, but can be reliably reproduced multiple times on a die across...
