Abstract

With the development of IT Info-Communications technology, the vehicle with a combination of wireless-communication technology has resulted in significant research into the convergence of the component of existing traffic with information, electronics and communication technology. Intelligent Vehicle Communication is a Machine-to-Machine (M2M) concept of the Vehicle-to-Vehicle. The Vehicle-to-Infrastructure communication consists of safety and the ease of transportation. Security technologies must precede the effective Intelligent Vehicle Communication Structure, unlike the existing internet environment, where high-speed vehicle communication is with the security threats of a wireless communication environment and can receive unusual vehicle messages. In this paper, the Vehicle Identification number between the V2I and the secure message communication protocol was proposed using hash functions and a time stamp, and the validity of the vehicle was assessed. The proposed system was the performance evaluation section compared to the conventional technique at a rate VPKI aspect showed an approximate 44% reduction. The safety, including authentication, confidentiality, and privacy threats, were analyzed.

IT 정보통신 기술의 발달로 인하여 차량통신분야쪽에서 정보, 전자, 통신기술이 융합된 지능형 교통 시스템의 연구가 활발히 진행되고 있다. VANET환경에서는 주로 차량과 차랑간의 통신, 차량과 기반 시설간의 통신을 하고 있으며 교통의 편의성 및 안전성을 제공하고 있다. 효율적인 지능형 차량통신을 구축하기 위해서는 보안 기술이 정립되어야 하고, 정적인 네트워크 환경과는 달리 동적인 고속의 이동성을 가지는 VANET환경에서는 차량 통신간의 무선 보안 위협과 많은 취약점이 존재한다. 그러므로 본 논문에서는 VANET 환경에서 차량의 차대번호를 사용하여 이를 신원기반 암호기술로 암호화 하여 안전한 메시지 통신 프로토콜을 설계한다. 제안하는 프토로콜은 차량의 차대번호와 RSU의 일련번호를 활용하여 차량을 등록하고, 신원기반 암호화 방식의 안전한 통신 프로토코을 설계한다. 성능 평가부분에서는 기존의 VPKI 기술과 비교하여 속도적인 측면에서 약 44%의 감소하였으며, 안전성에서는 인증, 메시기 기밀성 및 프라이버시 위협등을 분석하였다.
