CEKD: Computationally Efficient Key Distribution Scheme for Vehicular Ad-Hoc Networks

In vehicular ad-hoc networks, secure and reliable group communication is an energetic area of research. Today, the most important research challenge is an efficient group key distribution for a secure group communication. Even though there are many group key distribution protocols, they have the security and performance weakness. In this paper, we propose a computationally efficient group key distribution scheme for secure group communication based on bilinear pairing. The proposed CEKD scheme provides better performance in comparison with most of the previously proposed key distribution schemes in terms of computation cost, making it suitable for secure group communication in VANETs.
