A Stateless Cryptographically-Secure Physical Unclonable Function

Charles Herder, Ling Ren, Marten van Dijk, Meng-Day (Mandel) Yu, and Srinivas Devadas


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 \emph{no} information stored between subsequent queries, which mitigates attacks against the PUF via tampering. Moreover, our stateless construction corresponds to a PUF whose outputs are free of noise because of internal error-correcting capability, which enables a host of applications beyond authentication. We describe the construction, provide a proof of computational security, and present experimental evidence that this construct is viable.
