Vehicular Communication (VC) systems are being developed primarily to enhance transportation safety and efficiency. Vehicle-to-vehicle communication, in particular frequent cooperative awareness messages or safety beacons, have been considered over the past years as a main approach. Meanwhile, the need to provide security and safeguard the users privacy is well understood, and security architectures for VC systems have been proposed. In this paper, the authors provide answers to these questions, investigating the joint effect of a set of system parameters and components. They consider the state-of-the-art approach in secure VC, and they evaluate analytically and through simulations interdependencies among components and system characteristics.
