XML(extensible Markup Language)은 인터넷 기반 정보시스템의 정보 교환 양식으로 그 활용도가 증가하고 있으며, 여러 형태의 문서를 통합하고 전달하는 전자거래의 표준으로 인식되고 있다. 이러한 환경에서 전자거래 시 교환되는 XML 문서의 보다 안전한 보안 서비스를 하기 위한 방안으로 새로운 기술과 기존의 기술들을 융합할 수 있는 모듈화 되고 확장된 보안 기술이 필요하다. XML 정보보호기술 중 XML 키 관리 명세(XKMS)는 다양하고 복잡한 기능의 전자거래 어플리케이션에서 XML 문서의 서명을 검증하거나 암호화하는 공개키의 관리를 위한 프로토콜을 정의한다. 본 고에서는 XML 기반 보안서비스 특성에 착안하여 안전한 전자거래를 위한 XML 키 관리 기술과 표준화 과정에서 논의되고 있는 기술적 이슈에 대해 살펴보고 국내외 동향을 알아보고자 한다.
