Abstract
An analog hashing system and method includes: an input port for accepting an input signal; a chaotic circuit including non-linear components and multiple chaotic attractors for generating an unpredictable output responsive to the input signal; a differential output port coupled to the chaotic circuit for producing an analog differential signal from the unpredictable output; and a clock circuit for producing a binary output, as a hash function, generated by the sign of the analog output in every clock cycle.
