Abstract
3G telecommunication and wireless LAN provide various wireless communication services with their own native advantages and disadvantages. Currently WiBro service was developed to make up for the disadvantages of those services, and 3G-WLAN-WiBro underworking system which enables a user who uses triple-mode terminals to use those three networks was proposed. Even though each network adopts mutual authentication process between users and networks to provide security and accounting, they use different authentication protocols. In this paper, integrated authentication and key management protocol is proposed which makes use of previously used authentication information and supports safe roaming when a user moves from one network to another one under a same service provider on the 3G-WLAN-WiBro interworking network.
