초록

그룹 키 동의 프로토콜은 일련의 그룹을 형성하는 다수의 통신 참여자들이 공개된 통신망 상에서 안전하게 그룹의 공통 비밀키를 설정할 수 있는 방법을 제공해준다. 그룹 키 동의 프로토콜에 관한 연구는 그동안 많은 연구자들에 의해 다양한 관점에서 진행되어왔다. 하지만, 고성능 컴퓨터와 상대적으로 계산능력이 떨어지는 모바일 단말기가 혼재되어 있는 네트워크 환경에서의 그룹 키 동의 프로토콜에 관한 연구는 아직 전무한 실정이다. 따라서 본 논문에서는 이러한 유무선 통합 네트워크 환경에 적합한 그룹 키 동의 방식을 제안한다. 제안된 방식은 키 설정 프로토콜의 안전성 요구사항을 모두 만족할 뿐만 아니라, 효율성과 확장성 또한 매우 뛰어나다.

Group key agreement protocols are designed to allow a group of parties communicating over a public network to securely establish a common secret key. Over the years, a number of solutions to this problem have been proposed with varying degrees of complexity. However, there seems to have been no previous systematic look at the growing problem of key agreement over combined wired/wireless networks, consisting of both high-performance computing machines and low-power mobile devices. In this paper we present an efficient group key agreement scheme well suited for this networking environment. Our scheme meets efficiency, scalability, and all the desired security requirements.
