MANAGEMENT SYSTEM OF A SECURITY CERTIFICATE IN AN IP(INTERNET PROTOCOL) COMMUNICATION NETWORK FOR PROVIDING AN AUTOMATION METHOD CAPABLE OF BEING AUTOMATICALLY USED IN AN IP TERMINAL AND A METHOD THEREOF
PURPOSE: A management system of a security certificate in an IP(Internet Protocol) communication network and a method thereof are provided to efficiently manage a certificate revocation list by arranging the certificate revocation list through an IP terminal.;CONSTITUTION: IP(Internet Protocol) PBX(Private Branch Exchange)(200) requests security certificates of all IP terminals(S10). The security certificates are transmitted to the IP PBX(S20). An IP terminal(100) requests the security certificate of the IP PBX in case of communicating with the IP PBX for the first time(S30). The security certificate is received from the IP PBX(S40). A certifying authority(300) transmits a changed security certificate to the IP PBX(S50). A certificate revocation list is transmitted to the IP terminal(S60). The IP terminal requests the changed security certificate of the IP PBX by determining the validity of the security certificate currently used(S70). The IP PBX transmits the changed security certificate to the IP terminal(S80).;COPYRIGHT KIPO 2012
