Abstract
Research related to the authentication schemes in vehicular ad hoc networks (VANETs) has received significant attention recently. They substantially impact the security and privacy aspects of the message dissemination process in the road environment. Some authentication schemes with certificateless aggregate signature (CLAS) in VANETs have been published since the first related article emerged in 2015. This paper comprehensively reviews most of them regarding their main feature, contributions, security, and performance efficiency, as the state-of-the-art of all CLAS mechanisms in VANETs. Finally, the conclusion and some open issues on the CLAS authentication scheme in VANETs are provided in this survey.
