Abstract

The invention discloses a quantum secret key distribution method with a function of bidirectional identity authentication, and the method comprises the steps: carrying out the interception detection, identity authentication and secret key distribution based on Bell state entangle properties, and then completing the identity authentication and secret key distribution through primary quantum sequence transmission; firstly detecting the channel safety, secondly carrying out the identity authentication, and finally carrying out the secret key distribution. According to the invention, the method carries out the interception detection, identity authentication and secret key distribution based on Bell state entangle properties, and then completes the identity authentication and secret key distribution through primary quantum sequence transmission, thereby improving the utilization efficiency of particles and communication efficiency, and enabling a protocol to be more concise. The protocol has the characteristic of zero knowledgeability during identity authentication. Even if a user is simulated, a simulator still cannot obtain any valuable information in the communication, thereby further guaranteeing the information safety of the user. When two sides need to carry out the secret key distribution, the protocol firstly detects the channel safety, secondly carries out the identity authentication, and finally carries out the secret key distribution.

Description

Technical field [0001] The invention belongs to the field of quantum communication technology, and in particular relates to a quantum key distribution method with two-way identity authentication. Background technique [0002] Compared with the classical key distribution, quantum key distribution QKD (Quantum Key Distribution) is that the two communicating parties use quantum states as the carrier of information, and then transmit it through the quantum channel, while using the classical channel as an auxiliary tool, and finally to the communicating parties Distribute keys for confidential communication. The security of QKD is ensured by the Heisenberg uncertainty principle, quantum unclonability theorem, and the relevance and nonlocality of entangled particles in quantum mechanics. As early as 1984, Bennett of the United States and Brassard of Canada jointly developed the world's first QKD (BB84 protocol) using the polarization state of a single photon; in 1992, Bennett also pro...
