A Secure and Efficient Group Authentication Framework for Blockchain-Enabled Vehicular Edge Computing Systems

Maintaining privacy and trust within Vehicular Edge Computing (VEC) systems requires proper authentication methods that ensure safety and effectiveness in dynamic settings. Current authentication solutions face three main drawbacks including excessive computational costs together with complex identity management systems and large security exposure. The proposed lightweight Multi-Entity Authenticated Group Key Agreement protocol serves blockchain-based VEC networks according to this research. MAGKA enhances authentication through bulk certification removal and reduces reliance on identity authentication and provides seamless vehicle traffic across edge networks. The solution provides VEC authentication with robust security and scalability demonstrated through security analysis of its ability to withstand attacks.
