摘要: ABSTRACT In ubiquitous environment, a user has been provided with service and mobility using various devices. The users’ network can be divided into home (a belongs to the through an authentication server) external (when moves or server is). Users use mobile device at network. this paper, when access in device, there is skim that securely by roaming private information (encryption key etc…) which gives If you these skims, order secure network.Keywords:Roaming, Authentication, Mobile Device, Security protocol (그림 1) 무선 통신 서비스의 흐름도 1. 서 론 IT기술의 발달로 사용자는 다양한 모바일 디바이스(모바일 폰, PDA, 노트북 등)를 이용 하며 길거리나 기차, 도서관 등 여러 장소에서 서비스를 제공 받을 수 있다. 1 참조)모바일 디바이스는 와이브로, HSDPA(High Speed DownlinkPacket Access), 랜 등의 기술을 이용한다[1,2,6]. 사용자의 인증 및 보안 기술은 통신에 따라 차별성을 갖는데 폰의 경우 회사의 센터 3G 통신에서는 USIM(Universal Subscriber Identity Module)카드를 이용한다. 랜의 서버인
