최근 몇 년 동안 컴퓨터 업계에서는 신뢰 컴퓨팅, 특히 TCG가 내놓은 새로운 표준에 대한 필요성과 기능, 그리고 새로운 가능성이 큰 이슈가 되어 왔다. TCG는 세계 IT 업계의 핵심 기업들이 중심이 되어 설립된 비영리 업계 단체로서 PC를 필두로 컴퓨팅 환경의 보안성 향상을 목표로 하고 있고, 이에 따른 여러 제품들이 출시되고 있다. TCG 관련 제품 중 특히 TPM을 탑재한 PC 및 handheld PC가 국내 시장에서도 보급되고 있고, 전세계적으로는 연간 5천만 대 이상이 TPM을 채용하고 있다. 이제 신뢰 컴퓨팅을 적용할 다음 목표는 임베디드 시스템 분야가 될 것으로 전망된다. 본 고에서는 신뢰 컴퓨팅의 개념을 설명하고 TCG의 최근 동향과 애플리케이션을 살펴본다. 그리고, TCG에 속한 다양한 워킹 그룹들 중 특히 모바일 폰 워킹 그룹(MPWG)에 대하여 고찰한 후 결론을 맺는다.
