Abstract:This study proposes a two-party quantum identity authentication protocol that does not require the participation of a third party. The protocol can verify the user’s identity without exposing the authentication key information, and it can be implemented with a single-photon state, which does not involve entanglement, enabling it to be combined with existing technologies. The shared key is protected by the protocol and hidden during communication, and the security of the authentication scheme is analyzed and ve… Show more
