Authentication method, apparatus and system used in quantum key distribution process

摘要: The present application discloses an authentication method used in a QKD process, and further additional methods corresponding apparatuses, as well system. comprises: selecting, by transmitter according to basis selection rule, of preparation for information that is generated with first pre-provisioned algorithm varies dynamically, transmitting quantum states containing key the information; measuring, receiver, ending process if measurement result inconsistent calculated algorithm. By means this technical solution, dynamic requestor can be achieved defense provided against spoofing attacks, man-in-the-middle attacks distributed denial service (DDoS) security improved; furthermore, waste resources avoided well.
