Vehicular Ad-hoc NETworks (VANETs) represent a rapidly emerging, particularly challenging class of MANETs. Vehicular Communications (VC) aim to enhance safety and efficiency of transportation systems. Vehicular applications will provide warnings on environmental hazards, traffic and road conditions and local information. In fact, vehicular networks emerge, among civilian communication systems, as one of the most convinces and yet most challenging instantiations of the mobile ad hoc networking technology. Vehicular Ad-hoc NETwork (VANET) needs security to implement the wireless environment and serves users with safety and non safety applications.
