This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

On the efficiency of secure beaconing in VANETs [PDF]
Direct inter-vehicle communication enables numerous safety applications like intersection collision warning. Beacons - periodic one-hop link-layer broadcast messages containing, e.g., location, heading, and speed - are the basis for many such applications. For security, current work often requires all messages to be signed and to carry a certificate to

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

Leveraging GRU Networks for Robust and Efficient Vehicular Channel Estimation
Precise channel estimation becomes vital in robust vehicular communication, particularly in high‐mobility scenarios where conventional techniques such as Least Squares (LS), Minimum Mean Square Error (MMSE), Data Pilot‐Aided (DPA), and Orthogonal Matching Pursuit (OMP) methods frequently fail owing to error propagation and computational inefficiencies.

This article proposes a meta‐architectural framework for cyber‐physical transportation systems (CPTS) that integrates physical infrastructure with cyber components through knowledge elicitation and a clustering‐based design structure matrix (DSM). The approach enables adaptive system behaviour, improves interoperability and supports sustainable urban ...

Securing Machine‐Type Communications: A Survey on Privacy Threats and Countermeasures
Machine‐type communication (MTC) is a fundamental enabler of the Internet of Things (IoT) and emerging 5G/6G networks, supporting massive deployments of heterogeneous and resource‐constrained devices. However, large‐scale data collection, persistent connectivity, and limited device capabilities introduce critical privacy challenges that are not ...

This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...
