Analog circuits for physical cryptography
This paper presents circuit designs to be used as `public-key' physical uncloneable functions. We will introduce two specially designed circuits: `skew' memories and massively parallel analog processor arrays (CNNs). We show that such circuits-which are possible to simulate but computationally outperform any feasible digital and hardware-assisted emulation-can be used to remotely and securely identify their owner and serve as a basis for various cryptographic protocols.
