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.

Hoc Networks

Vehicular ad hoc networks, known as VANETs, are deployed to improve passenger comfort as well as to reduce the risk of road accidents by allowing vehicles to provide a warning in real time when a critical event is detected. In such networks, communication is possible both between the vehicles themselves and between the vehicles and the infrastructure. These applications need a reliable and secure broadcast system that takes into consideration the security issues in VANETs, the high speed of nodes, and the strict QoS requirements. For these reasons, the authors propose a trust-based and centralized TDMA-based MAC protocol that avoids time slot assignment to malicious nodes and minimizes message collision. The solution is based on the design of a generic trust mechanism for VANETs based on the MAC requirements and its integration into a centralized TDMA-based MAC protocol, named trust-CTMAC. The mechanism will permit roadside units (RSUs) to manage trust level assignment via security check during free slot allotment. The experiments carried out and the results obtained prove the effectiveness of the approach.

Sybil Attacks

Vehicular ad hoc networks (VANETs) are a class of ad hoc networks in which vehicle communicate with each other to show the traffic situation and any mishappening on the road. VANET is vulnerable to a number of attacks due to its infrastructure-less nature. One of these attacks is the Sybil attack. Security of data dissemination in VANET is very crucial, otherwise any mishappening can occur on road. Sybil attack is very difficult to be defended and detected, especially when it is launched by some conspired attackers using their legitimate identities, and this has become a growing research interest in VANETs in past few years. This chapter studies various dimension of VANETs including its structure, communication architecture, security issues, and critical review of technique to detect Sybil attacks.

Hoc Networks

Vehicular ad-hoc networks (VANETs) are a promising communication scenario. Several new applications are envisioned, which will improve traffic management and safety. Nevertheless, those applications have stringent security requirements, as they affect road traffic safety. Moreover, VANETs face several security threats. As VANETs present some unique features (e.g. high mobility of nodes, geographic extension, etc.) traditional security mechanisms are not always suitable. Because of that, a plethora of research contributions have been presented so far. This chapter aims to describe and analyze the most representative VANET security developments.

Continuous Progression

Recently, vehicular ad hoc networks (VANETs) got much popularity and are now being considered as integral parts of the automobile industry. As a subclass of MANETs, the VANETs are being used in the intelligent transport system (ITS) to support passengers, vehicles, and facilities like road protection, including misadventure warnings and driver succor, along with other infotainment services. The advantages and comforts of VANETs are obvious; however, with the continuous progression in autonomous automobile technologies, VANETs are facing numerous security challenges including DoS, Sybil, impersonation, replay, and related attacks. This paper discusses the characteristics and security issues including attacks and threats at different protocol layers of the VANETs architecture. Moreover, the paper also surveys different countermeasures.
