Performance of Revocation Protocols for Vehicular Ad-Hoc Network. Review of State-of-Art Techniques and Proposition of New Enhancement Revocation Method
2018
Security is one of the most important issues concerning Vehicular Ad-Hoc Networks (VANETS), specifically when dealing with misbehaving vehicles to prevent them threatening the safety of others. In this paper, we present a review about revoking misbehaving vehicles based on classical Certificate Revocation List (CRL) in IEEE Standard. The main disadvantage of these algorithms resides in the fact that the Certification Authority (CA) is overwhelmed because it is responsible to distribute the whole CRL to all the requesting vehicles. To overcome this drawback in European Telecommunication Standards Institute (ETSI) standard, we propose our contribution that aims to minimize the tasks of the CA, by decomposing the CRL into different chunks that are distributed separately by the different RSUs of the same zone.
