Abstract

급속산 암호의 민간 부문 확산에 따라 암소 사용으로 인한 부작용을 방지하기 위한 대책으로 키 복구에 대한 연구가 활발히 진행되고 있다. 그러나 지금까지 제시된 기존의 키 복구 기술들은 그 대부분이 정부의 법 집행권 보장에만 설계초점을 맞추고 있기 때문에 다양한 사용자들의 요구를 충족시키기 어렵다. 본 논문에서는 키 복구 시스템에 대한 사용주체들의 입장을 고려하여 다양한 환경에서 사용할 수 있는 키 복구 시스템을 제안한다. 제안하는 방식은 암호통신 과정 중에 키가 분배되는 일방향 키 분배가 가능하고 기존의 시스템만큼 효율적이며, 충분한 유연성을 제공한다.
