US Patent 11924335 Systems and methods for quantum session authentication

Systems, apparatuses, methods, and computer program products are disclosed for session authentication. In an exemplary embodiment, a session authentication system encodes and decodes a set of quantum bits using different quantum bases in order to generate a random number used to generate a session key or a random seed (e.g., a set of bits that is randomized due to quantum effects such as the principle of quantum uncertainty) for pseudorandom number generation used to establish a secure session. An example system includes decoding circuitry configured to receive, over a quantum line, a set of qbits generated based on a first set of quantum bases not received by the decoding circuitry, and decode, based on a second set of quantum bases, the set of qbits to generate a decoded set of bits; and session authentication circuitry configured to generate a session key based on the decoded set of bits.
