SECURE PAYMENT AND AUTHENTIFICATION SYSTEM HAVING ENHANCED SECURITY WITH QUANTUM CRYPYOGRAPHY

摘要

The present invention relates to a communication technology capable of encryption communication and authentication based on a quantum cryptography, and more particularly, to a communication system in which a quantum cryptography based encryption using a repeater is provided between a communication terminal and a server in order to improve security of an alternative payment system based on mobile commerce Communication devices and authentication, payment and transaction methods. The present invention generates a secret key in a repeater or a server through encrypted communication based on quantum cryptography with a relay station or a server including a communication terminal including an optical transmitter and a light receiver, and shares the generated secret key with a communication terminal And to provide mobile commerce through user authentication.
