휴대용 컴퓨터가 널리 보급됨에 따라 장소에 상관없이 네트워크 망에 연결시킬 수 있는 수단으로 무선 랜의 필요성이 증대되고 있다. 이에 따른 정보보호 문제 또한 중요한 현안으로 대두되고 있다. 현재 IEEE 802.1X를 중심으로 무선랜에서의 향상된 정보보호 솔루션을 제공하기 위한 노력이 진행 중에 있다. 하지만, 무선 랜 환경에서 안전하고 빠른 handoff를 지원해 주기 위한 방안은 부족한 상황이다. 이러한 필요성에 따라 본 논문에서는 무선 LAN환경에서 빠른 handoff를 제공하는 Proactive handoff를 지원하기 위한 안전만 보안 방법론을 제안한다. 이 때 키 교환 메커니즘으로 EAP-TLS를 이용한 방법을 토대로 한다.
