Abstract

A physically unclonable function (PUF) device includes a hybrid Boolean network module of a ring of N number of Boolean nodes connected end to end and a sampling module, wherein the hybrid Boolean network module comprises N number of xor logic gates and corresponding N number of multiplexers, wherein a function change module is disposed between an output end of a first xor logic gate of the N number of xor logic gates and an input end of a first multiplexer of the N number of multiplexers, wherein each Boolean node is provided with four input ends and three output ends, the four input ends respectively connected to an output end of each of two juxtaposing Boolean nodes, an initial excitation signal and a control delay signal, the three output ends respectively output to an input of each of two juxtaposing Boolean nodes, and the sampling module.
