ABSTRACT:
Provided is a method of key agreement between devices. Using the method, two devices on a network can exchange information using polynomials of a polynomial ring, authenticate each other using the exchanged information, and generate a shared key. Accordingly, an authenticated key agreement protocol, which has better security and a faster processing speed than a conventional encoding system, can be realized.
