The present invention relates to a technology for a server and a communication terminal enabling cryptographic communication based on quantum cryptography, and more specifically, to: a cryptographic communication device based on quantum cryptography at a server and a communication terminal for improving the security of an alternative payment system based on mobile commerce; and an authentication/communication method thereof. The purpose of the present invention is to propose an authentication protocol using quantum cryptographic communication through a repeater between a server and a mobile terminal to reduce the size and the weight by improving a part of an authentication process via quantum cryptography. The purpose of the present invention is to propose an authentication protocol using quantum cryptographic communication between a mobile terminal and a server or a repeater, and to propose an authentication method capable of maintaining high security in mobile commerce and performing user authentication, via the authentication protocol. |
