Optimization of Security Oriented Authentication and Access Control Framework for Wireless Vehicular Communications

ABSTRACT The Vehicular Internet of Things (VIoT) is revolutionizing the way devices and digital assets communicate, enabling seamless data sharing without the need for human involvement. One of the standout features of VIoT is the immense volume of data generated by end‐user devices, which must be efficiently processed and transmitted to the cloud. Unfortunately, this process can be slow and detrimental to network performance. To tackle these challenges effectively, edge computing emerges as a powerful solution. By decentralizing information processing to the network edge, this innovative architecture significantly enhances operational efficiency, especially within the automotive sector. However, the substantial volume of data produced by these devices can significantly hinder processing efficiency and compromise overall network performance. Despite its advantages, vehicular networking is vulnerable to malicious attacks, underscoring the urgent need for a strong and secure authentication framework. A lattice‐based cryptographic approach offers exceptional privacy and security, making it an ideal choice for VIoT‐enabled vehicles and enhancing the future of smart transportation. In this paper, we introduce an innovative authentication and access control protocol based on a lattice‐based cryptosystem for wireless vehicular communication. Our analysis shows that our proposed scheme is highly efficient and effective compared to existing methods, paving the way for safer and smarter transportation systems.
