Security in vehicular ad hoc networks

TLDR

Vehicular communication networking promises road safety, traffic management, and infotainment, while its design must resist malicious abuses and security attacks. The article reviews the standardization process for security and privacy in WAVE applications and addresses certificate revocation and conditional privacy preservation. The authors review standardization, tackle certificate revocation and conditional privacy, and introduce novel mechanisms to achieve secure revocation and privacy. They present novel security mechanisms that enable secure certificate revocation and conditional privacy, addressing key challenges in vehicular ad hoc networks.

Abstract

Vehicular communication networking is a promising approach to facilitating road safety, traffic management, and infotainment dissemination for drivers and passengers. One of the ultimate goals in the design of such networking is to resist various malicious abuses and security attacks. In this article we first review the current standardization process, which covers the methods of providing security services and preserving driver privacy for wireless access in vehicular environments (WAVE) applications. We then address two fundamental issues, certificate revocation and conditional privacy preservation, for making the standards practical. In addition, a suite of novel security mechanisms are introduced for achieving secure certificate revocation and conditional privacy preservation, which are considered among the most challenging design objectives in vehicular ad hoc networks.
