최근 들어 디지털 포렌식 분야에서 가장 중요한 요소 중 하나는 속도이다. 하드 디스크 기술의 바ㅏㄹ전으로 용량은 Terabyte 급으로 증가되는 반면 가격은 점점 하락하고 있다. 이러한 추세는 디지털 포렌식을 수행하기 위한 이미지 생성, 검색, 분석 등의 과정에 엄청난 시간이 소요되어야 한다는 것을 의미한다. 이러한 문제를 해결하기 위해 고속화를 위한 여러 가지 접근법들이 제안되고 있다. 그 중 최근 각광을 받고 있는 접근 방법 중 하나는 하드웨어를 이용하는 것이다. 하지만 이러한 하드웨어를 이용한 접근법은 이미지생성 작업에 한정되어 왔고 하드웨어를 사용한 검색 작업은 아직까지 미진한 상황이다. 본 논문에서는 Tarari Content Processor를 사용한 고속 검색 엔진을 설계하고 이에 대한 성능을 기존 소프트웨어 기반의 포렌식 검색 툴과 비교함으로써 하드웨어 기반 검색의 유용성에 대해 논의하고자 한다.
