  • Devices, systems, methods, and computer-readable media for zero knowledge proof authentication
    Patent number: 11258606
    Abstract: Security-enhancing devices, systems, methods, and non-transitory computer-readable media for performing non-interactive zero knowledge proof (NIZKP) authentication. In one embodiment, a computing device includes a memory and an electronic processor. The memory stores a NIZKP authentication program and a plurality of unique passwords. The electronic processor is configured to receive a first random value from an electronic source, generate a second random value by performing an exclusive disjunction operation on the first random value with a first password of the plurality of unique passwords, perform an extraction operation on the second random value, determine whether the extraction operation performed on the second random value extracted a non-random value from the second random value, and responsive to determining that the extraction operation performed on the second random value extracted the non-random value from the second random value, authenticate communications with the electronic source.
