Abstract

With increase of electric vehicle in the road, the number of charging/discharging infrastructure for electric vehicle in public space is also increased rapidly. To charge or discharge the electric vehicle the user of electric vehicle and service provider should verify the each other's identity to minimize security vulnerability. This paper proposes mutual authentication scheme between electric vehicle and charging/discharging service provider with help of hash function and Message Authentication Code(MAC). Also efficient operating scheme for charging/discharging service system is proposed. The analysis shows that the system has robustness against security vulnerability. Also this system can keep the sensitive personal information of service user safely.

전기자동차의 증가에 따라 공공장소의 전기자동차 충방전 기반시설 또한 급격히 늘어나고 있다. 전기자동차의 충방전을 위해서는 보안상의 취약점을 최소화하기 위해 전기자동차와 서비스 제공자가 서로의 신원을 확인하는 상호인증과정 후에 층방전 서비스를 시작하여야 한다. 본고에서는 해쉬함수와 메시지 인증코드를 사용하여 전기자동차와 충방전 서비스 제공자간의 양방향 인증 방법을 제안한다. 그리고 효율적인 충방전 시스템의 운영에 대해 기술한다. 제안된 시스템은 외부로 부터의 공격에 강한 내성을 가지며 충방전 서비스 이용자의 개인정보를 효과적으로 보호할 수 있다.
