Feasibility Analysis of Quantum Key Distribution Technology in Unique Code Application

Unique code system (UQS) can solve the security problem of the key system well, but it is insufficient in dealing with human malicious behavior. Quantum key distribution can ensure that any attempt to steal the key in transit will be discovered by legitimate users. The combination of quantum key distribution technology and UQS technology can effectively deal with the occurrence of malicious initiation events. This paper analyzes the feasibility of quantum key distribution technology in the application of UQS and looks forward to the application prospect in the field of security control of critical systems.
