WiBro(휴대 인터넷)는 언제 어디서나 고속으로 무선 인터넷 접속이 가능한 서비스를 위한 기술이다. 노트북을 비롯한 휴대가 간편한 PDA, 스마트폰으로 사람이 보행 또는 차량 주행 중에서도 끊김없이(seamless) 무선 인터넷서비스가 가능하다. 휴대 인터넷 서비스는 무선랜과 3G 이동통신이 제공하는 데이터 통신을 융합하고, 두 서비스의 단점을 보완하는 형태의 무선 통신 서비스라고 할 수 있다. 이동성과 고속 무선 통신이 가능한 서비스에서 가장 중요한 기술 요소 중 하나가 보안이다. 본 논문은 안전한 서비스를 제공하기 위하여 WiBro 무선 네트워크에서의 UICC 기반의 EAP-AKA 인증 프로토콜을 적용한 사용자 인증 메커니즘의 상세한 프로토콜을 제안한다. 따라서 EAP-AKA 기반의 무선 네트워크 인증을 통하여 WiBro 무선 네트워크에서 뿐만 아니라 USIM 기반의 WCMDA 등의 이기종 무선 네트워크와의 연동(interworking)에서도 보다 효율적으로 적용할 수 있다.
