Abstract

Revocation of malicious nodes in vehicular ad hoc network (VANET) is the major issue that has received a lot of attention. This paper mainly focuses on developing a mechanism for revoking the misbehaved node in VANET. The current approaches mainly rely on certificate revocation list (CRL) to distribute the certificate revocation information which incurs a long delay based on the CRL file size (bytes to megabyte), high processing overhead, storage space and consumes more resources for certificate validation. To achieve the purpose of this paper, Merkle Hash Tree (MHT) is constructed for distributing the information about the revocation of certificates. Certificate authority (CA) is the trusted third party in the vehicular cloud (VC) which issues certificate to the vehicles through the road-side unit (RSU).
