Abstract

In this paper, we propose an efficient authentication protocol based on certificateless signature scheme, which does not need anyinfrastructure to deal with certification of public keys, among the vehicles in Vehicular Ad-hoc Networks. Moreover, due to the characteristicsof VANET nodes (i.e., vehicles) that is fast and movement, the proposed protocol introduces the concept of interval signing key to overcome efficiently the problem of certificate revocation in traditional Public Key Infrastructure(PKI).

본 논문에서는 Certificateless 서명기법을 이용하여 Vehicular Ad-hoc 네트워크에서 공개키 인증서 관리 및 취소 문제를 다루지 않는 효율적인 인증 프로토콜을 제안한다. 또한, 빠르고 동적인 Vehicular Ad-hoc 네트워크의 노드(Vehicles)들의 특성을 고려하여 전통적인 공개키 구조에서의 인증서 취소 문제를 보다 효율적으로 해결하기위하여 구간 서명키 개념을 도입한다.
