오늘날 차량 교통 시스템은 지능형 교통 시스템(ITS, Information Transportation System) 으로 진화하고 있다. 특히 차량 간 통신 및 차량과 인프라 간 통신을 활용하여 차량 주행의 안전성을 높이고 교통 체계의 운영 및 관리를 과학화하고자 하는 연구가 활발히 진행 중이다. 그러나, 지능형 교통 시스템의 상용화를 위해서는 차량 통신 보안 기술의 확보가 필수적이다. 본 고에서는 차량 통신 시스템의 개요 및 보안 요구 사항 그리고 보안 위협들을 살펴 보고, 현재 IEEE 에서 추진 중에 있는 차량 통신 표준인 WAVE(Wireless Access in Vehicular Environment)에 적용되는 보안 기술을 소개한다.
