Abstract
정보통신이 발달함에 따라서 모바일 환경은 주된 통신 환경으로 자리잡았다. 모바일 환경은 유선환경 보다 개방된 네트워크 특성으로 인하여, 서비스를 이용함에 따라 사용자의 개인정보에 대한 스니핑이나 피싱, 불법 단말기의 사용으로 개인정보가 노출 될 수 있다. 따라서 신뢰 컴퓨팅을 표준화 하고 있는 TCG(Trusted Computing Group)는 모바일 환경의 보안을 위해 하드웨어 기반의 보안 모듈인 MTM(Mobile Trusted Module)을 제안하였다. MTM은 플랫폼에 임베디드되어 사용자 프라이버시와 플랫폼 무결성을 보호하고 물리적으로 안전하지만 강한 보안 기능을 제공하는 만큼 비밀 데이터를 다른 곳으로 이전할 때 보안적인 접근이 요구된다. 본 논문에서는 TCG 보안 기술과 함께 암호키 이전 방안에 대해서 살펴보고, 키 백업과 복구를 적용한 안전한 암호키 이전 방안을 제안한다.
