Abstract

With help of Vehicle-to-Grid(V2G) technology battery in electric vehicle can be used as distributed energy resource and energy storage in a smart grid environment. Several problems of security vulnerability and privacy preservation can be occurred because V2G network supports 2 way communication among all components. This paper explains and makes analysis of architecture, privacy sensitive data, security vulnerability and security requirement of V2G system. Furthermore efficient architecture and operating scheme for V2G system are proposed. This scheme uses symmetric cryptosystem and hash algorithm to support privacy preservation and mutual authentication.

Vehicle-to-Grid(V2G) 기술은 전기자동차의 배터리를 분산발전원 및 에너지 저장장치로의 이용하려는 기술로 스마트그리드의 주요한 한 부분을 차지하고 있다. V2G 네트워크는 양방향의 통신망을 사용함으로 피할 수 없는 보안 취약점과 개인정보보호의 문제를 가지고 있다. 본고에서는 V2G 시스템의 구조, 사용되는 개인정보, 보안취약점 및 보안 요구사항에 대해 자세히 알아보고 분석한다. 그리고 V2G 시스템의 특성을 고려하여 효율적인 V2G 시스템의 구조와 운용방안을 제안한다. 제안하는 방식은 대칭키 암호와 해쉬 알고리즘을 이용하여 개인정보의 유출을 방지하고 양방향 인증을 수행하며 개인정보 유출의 위험성을 최소화 한다.
