Method and System for Authentication and Key Agreement through One Time Quantum Symmetric Key based on Elliptic Curve Diffie Hellman Algorithm

摘要

The present invention relates to a method and system for authentication and key agreement using a one-time quantum symmetric key based on an elliptic curve Diffie Hillman. In the present invention, the first device is a secret key and a quantum random number And create Public key And the first device is a quantum random number As public key Performing an electronic signature (SIG_a) for the first device, and the public key And the algorithm type and the step of transmitting the digital signature (SIG_a) to the second device, and the second device is a quantum random number as a secret key. And the public key And the second device is a quantum random number As public key The step of performing an electronic signature (SIG_b) for the second device, and the public key And transmitting the electronic signature (SIG_b) to the first device, and the first device The digital signature (SIG_b) is verified through And verifying the digital signature (SIG_a) through.
