Physical model for B92-QKD authentication based on analogy with optical chaotic systems

Information and communication security are one of the most global security issues. As a solution of this problem emerge quantum key distribution, technology that guarantees security by the laws of physics. But without authentication this technology is also subjected to cyberattacks. In this paper physical model for authentication of B92 protocol is proposed and explained. Based on analogy with optical chaotic systems this model gives advanced security in comparison to so far proposed systems.
