SECURE PAYMENT AND AUTHENTIFICATION SYSTEM HAVING ENHANCED SECURITY WITH QUANTUM CRYPYOGRAPHY

摘要

The present invention relates to a communication technology capable of performing quantum cryptography-based cryptographic communication, and more specifically, to a quantum cryptography-based cryptographic communication apparatus through a relay between a communication terminal and a server, and an authentication, payment and transaction method thereof, to increase security of a mobile commerce-based book entry payment system. The objective of the present invention is to generate a secrete key through a quantum cryptography-based cryptographic communication between a communication terminal including an optical transmitting unit, and a relay or server including an optical receiving unit, and share the generated secrete key with the communication terminal, so as to provide mobile commerce through user authentication.
