Abstract
Disclosed herein are a quantum cryptography-based cryptographic communication system and an authentication, payment and transaction system via a relay device between a communication device and a server. A relay device for quantum cryptography authentication includes an optical receiver unit, an optical transmission unit, and a processor. The processor includes a quantum signal control unit, a user authentication unit, and a random number generation unit. The optical receiver unit receives a series of second quantum signals generated in such a manner that a series of first quantum signals generated by a first quantum filter and sent from a communication device pass through the second quantum filter of the relay device or a reception side, and the optical transmission unit transfers the series of second quantum signals to a server.
