Method of establishing secure transport connection using TLS in Diameter-based AAA system

摘要

PURPOSE: A method for setting up transport security layer using a TLS(Transport Layer Security) in a diameter-based AAA system is provided to build an efficient and stable system by managing efficiently a time for TLS connection process and a computing resource. CONSTITUTION: A connection setup message of a transport layer is requested to the opposite party through a network in order to start a communication process(S41,S42). The connection setup message is processed by the opposite party(S43,S44). A response message is received from the opposite party(S45,S46). A CER(Capabilities-Exchange-Request) message is transmitted to the opposite party after the response message is received from the opposite party(S47,S48). The CER message is processed and an outgoing connection is released by performing a selection processor(S49,S50). A TLS handshake protocol is operated if a CEA(Capabilities-Exchange-Answer) message is received from the opposite party(S51-S53).
