Title
BAGKD: A Batch Authentication and Group Key Distribution Protocol for VANETs
Abstract
As an important application of mobile ad hoc networks, VANETs play an important role in intelligent transportation. However, with the development of mobile communication technology, as well as the needs of intelligent transportation, both security and efficiency are required for realtime authentication and communication. Traditional authentication and key distribution schemes suffer from network failure and high response latency. To solve the above problems, this article proposes a BAGKD protocol to achieve robust and efficient networking for the security and efficiency of VANETs. In our protocol, bilinear mapping is used to realize batch authentication, which can improve authentication efficiency and reduce message errors caused by factors such as high speed of vehicles. The group key distribution mechanism can update the group key dynamically, which reduces the risk of group key leakage effectively. For the sake of privacy protection, vehicles utilize pseudonyms issued by a trusted authority to communicate with RSUs. The security of BAGKD protocol is verified by simulation in our experiments on AVISPA. In addition, when compared to three existing protocols based on bilinear mapping, our proposed BAGKD outperforms them in terms of efficiency and communication overhead while maintaining security. The simulation results further confirm that BAGKD is suitable for short-range communication scenarios such as VANETs.
