US Patent 10999066 Brain-actuated control authenticated key exchange

A brain-actuated authentication key exchange (“BACAKE”) system facilitates multi-factor and mutual authentication of an individual to a provider computing system via a brain-computer interface. Neural signals are received from a brain-computer interface coupled to an individual. Physical movement intentions of the individual are extracted from the neural signals. The physical movement intentions are mapped to a character string representing a knowledge factor. A secure, mutually authenticated communication channel is established between the BACAKE computing system and a provider computing system by using the knowledge factor as an input to a password authenticated key exchange protocol.
