Certificate revocation in vehicular Ad Hoc networks: a novel approach

To manage the traffic load along with providing safety and updated information, vehicular communication networking is marching at a high pace in research area. But similar to other networks VANET is not free from vulnerabilities. This network has brought forward a number of sectors which demand security for continuing operations safely. Among them, this paper contributes to a burning issue- how network secrets are distributed confidentially among the legitimate members of the network. The recent mechanisms involve searching a database for identities of revoked entities which is time consuming. This paper proposes an efficient mechanism dropping the time consuming database searching and finally analyzes its security on known attacks while certificate revocation process.
