Method for Embodying a key agreement protocol

摘要

PURPOSE: A method for implementing the key agreement protocol is provided to secure a safety and security by using Braid group since a method for solving the solution of a polynomial time has not been found. CONSTITUTION: A method for implementing the key agreement protocol includes the steps of: defining(SA401) a pair of sub-groups GA and HA of Bn; randomly selecting(SA402) aA GA and bA HA; selecting(SA403) Bn; calculating(SA404) p; calculating(SA405) xA = aApbA; publishing(SA406) xA; receiving(SB407) xA; receiving(SA407) yB; and calculating(SA408) K = aAyBbA.
