An Efficient Cross Authentication Protocol in VANET Hierarchical Model
This paper proposes an efficient scalable authentication scheme for secure communication in Vehicular Ad-Hoc NETwork (VANET). The proposed protocol works on a hierarchical model and hence scalable. Security analysis shows the robustness against the conventional attacks and the simplicity of the protocol makes it cost efficient. Vehicular ad-hoc networks form a special class of mobile networks and have become an important area of study these days. Due to advancement in technology, embedded processors in vehicles and capability of communicating with each other, force the researchers to contribute to this field.
