摘要：Many new types of communication networks are emerging due to the proliferation of technology in various areas of daily life. Among the most interesting wireless networks, Vehicular Ad-hoc Networks are remarkable, because it is a self-organizing network of the vehicles that helps in enhancing road safety and transport efficiency. It has a wide range of applications that need a high level of security, as a single vehicle sending out false warnings can disrupt the traffic of the whole highway. Eviction of such misbehaving vehicle is a critical issue of the Vehicular Adhoc network. It can be done using public key infrastructure in which only certification authority can revoke the certificate of the misbehaving vehicle by issuing a Certificate Revocation List (CRL) periodically. However, it is necessary to improve many aspects related to security. This paper focuses on investigating the improved methods for certificate revocation and certificate revocation list dissemination in Vehicular Ad-hoc Networks (VANETs).
