Abstract
개인용 컴퓨터의 디스크 용량 증가와 저장, 분석되어야 하는 방대한 양의 데이터는 포렌식 수집과 분석 시간을 점점 더 요구하고 있다. 이에 ETRI는 대용량 데이터에 대한 고속 수집 및 검색, 분석을 가능하게 하는 고속 포렌식 시스템을 개발하였다. 포렌식 분석은 질의어에 대한 검색의 연속된 과정이라고도 할 수 있어 고속 포렌식 시스템은 하드웨어 가속기를 이용하거나 인덱스를 구축하여 고속으로 데이터를 검색하는 기술을 제공한다. 또한, 안티포렌식 기법중 하나인 파일 암호화는 문서 열람을 불가능하게 해 증거 발견을 어렵게 한다. 이에 고속 포렌식 시스템은 제한된 수사 시간을 고려하여 고속으로 패스워드를 해독하는 기능을 제공한다.
