WAVE(Wireless Access in Vehicular Environments) 통신 시스템은 차량 간 무선통신을 가능하게 해주는 환경을 지원한다. 무선통신의 활용이 증가함에 따라 그에 따른 공격 방법도 다양해져, 패킷들은 통신 시 제3자에 의해 변조될 수 있다. 본 논문은 CA(Certificate Authority)와 차량이 통신 과정에서 ECIES(Elliptic Curve Integrated Encryption Scheme)를 이용하여 자신이 적합한 호스트임을 인증 받고, AES(Advanced Encryption Standard) 알고리즘을 이용하여 패킷의 기밀성과 무결성을 보장하는 프로토콜을 제안하였다. The WAVE(Wireless Access in Vehicular Environments) communication system supports wireless communication environments between vehicles. As the utilization of wireless communication has been increased, attack methods have been varied. There is a high risk on packet manipulations conducted by third party. In this paper, we have designed a secure communication protocol between CA and vehicles. Our designed protocol uses a ECIES(Elliptic Curve Integrated Encryption Scheme) for vehicle authentication and AES(Advanced Encryption Standard) algorithm for protecting packet integrity and confidentiality.
