A Review of Security Aspects in Vehicular Ad-Hoc Networks

In recent years, cooperative systems have been gaining relevance in autonomous driving to such an extent that they are necessary to reach the final goal, the autonomous car. But the relevance that the Vehicular Ad-hoc NETworks (VANETs) have acquired shows that it is still an immature technology and needs more time to develop. Proof of this is that most of these systems do not provide real security in communications; so the scientific community has tried to develop new technologies to allow greater security in this type of communications. Therefore, in this paper, a review of how the technology has evolved to maintain safety in the VANETs will be carried out; in addition, a breakdown of the different security technologies grouped by their type and the advantages and disadvantages of each one.
