Abstract

Vehicular Ad-hoc NETworks (VANETs) currently provide a prominent field of research, which aims at improving everyday road safety and comfort. To achieve this, the deployment of several potential applications is envisioned, promising to provide extraordinary benefits, but will also represent important security challenges due to the unique characteristics of VANETs. In this chapter, VANET’s security issues are addressed, and the most outstanding security approaches are discussed. As a proof of concept, a PKI -based protocol, able to cope with the interoperability issues among untrusted CA domains is presented, and the trade-offs between security and performance are empirically analyzed and stressed.

Background

VANETs represent the most relevant form of MANETs and their successful deployment will allow the implementation of several interesting applications, primarily aimed at improving road’s overall safety and also capable of enhancing driver comfort. In this section we will first briefly introduce VANETs’ basic components and applications, and discuss the reasons why despite their potential benefits, VANETs also raise important security implications that must be solved. An extensive review of the literature focusing on VANETs’ authentication is then presented in the second part of this section.
