Secure Vehicular Communications Based on Group Signature and ID-Based Signature Scheme

Vehicular communication networking is a promising approach of facilitating road safety, traffic management, and infotainment dissemination for drivers and passengers. However, it is subject to various malicious abuses and security attacks which hinder it from practical implementation. In this paper, we propose a novel security protocol based on group signature and identity-based signature scheme to meet the unique requirements of vehicular communication networks. The proposed protocol not only guarantees security and anonymity, but also provides easy traceability property when the identity of the sender of a message has to be revealed by the authority. To further enable Internet access, the network architecture incorporating with the proposed security protocol is introduced. Simulation is conducted to analyze the system performance which proves the feasibility of the proposed scheme.
