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.

Analog hashing engines using physical dynamical systems

A microwave switch. In some embodiments, the microwave switch includes a substrate, a signal conductor, a first ground conductor, on a first side of the signal conductor, and a second ground conductor, on a second side of the signal conductor. The signal conductor, the first ground conductor, and the second ground conductor may be planar conductors on a planar top surface of the substrate. The signal conductor may have a first portion composed of a superconducting material, and a second portion having a reduced cross section, a cross-sectional area of the second portion being less than 120 nm.
