유비쿼터스 홈네트워크로 진화되어 감에 따라 디바이스가 다른 홈네트워크로 이동하여 서비스를 받는 경우가 증가하게 되고, 유비쿼터스 홈네트워크 환경을 구성하는 많은 디바이스들은 유기적으로 연결되어 서로 데이터를 주고받고, 이를 통해 서비스를 제공하게 될 것이다. 이러한 환경에서 디바이스의 다양성과 디바이스간 자원 공유 등으로 보안 측면에서 고려해야 할 요구사항은 더욱 복잡해지고 다양화될 것이다. 이러한 이유로 유비쿼터스 홈네트워크 환경에 적합하고, 보안 요구사항을 고려하여 안전한 서비스를 제공할 수 있는 경량화된 홈디바이스 인증/인가 기술 연구가 최근 국내외에서 활발히 진행되고 있다. 본 고에서는 유비쿼터스 홈네트워크 환경에서의 디바이스 인증/인가 기술에 대하여 소개하고, 국내외 기술 동향 및 관련 표준안의 주요 내용에 대하여 기술하고자 한다.
