Road Transport safety: VANET using cluster identity and Digital Certification

Abstract

Vehicular ad-hoc network (VANET) becomes an eye catching area for industry and academician. VANET   is going to provide tremendous benefits to future vehicle users. The communication among vehicle to vehicle, vehicles to RSU done over wireless network. For this reason, all are concern about the safety of data used in VANET. Weaker in security may produce problem similar as denial of service attack, masquerading attack and many more. Till now various security mechanisms propose to secure the VANET but they suffer with the problem of certificate distribution and revocation, communication overhead etc. This paper efficiently overcomes these issues in the sense that each RSU maintain a cluster instead of a centralized authority. We propose an algorithm using cluster identification and low message passing. We also compare our protocol with the existing one on the basis of time and computational also, we present a comparison graph between our protocol and the existing one.
