SECURITY METHOD OF A SERVER-BASED MOBILE INTERNET PROTOCOL SYSTEM, FOR REDUCING CALCULATING QUANTITY AND THE EXCHANGING NUMBER OF MESSAGES

摘要

PURPOSE: A security method of a server-based mobile internet protocol system is provided to safely execute communication in a mobile node in which the electric power and computational capacity are weak.;CONSTITUTION: A security method of a server-based mobile internet protocol system is composed of the steps of generating a server(20) and a tunnel by using a first security item exchanged by executing mPAK with a server(202), transmitting a similar password request message(PPQ) to the server through the tunnel(204), exchanging a second security item by executing mPAK with the correspondent node which wants communication by using a similar password answer message(PPA) received from the server by corresponding to the request, and producing the tunnel for security about data transmitted/received with the correspondent node and control message(209).;COPYRIGHT KIPO 2010
