In this paper, we introduce an anonymous batch authenticated and key agreement (ABAKA) scheme to authenticate multiple requests sent from different vehicles and establish different session keys for different vehicles at the same time. In vehicular ad hoc networks (VANETs), the speed of a vehicle is changed from 10 to 40 m/s (36-144 km/h); therefore, the need for efficient authentication is inevitable...
Transport safety applications aim at avoiding vehicular accidents by using secure broadcast vehicle-to-vehicle (V2V) communications. However, any security mechanism used for authenticating broadcast V2V messages comes with overhead in terms of computation and communications. The IEEE1609.2 standard for vehicular ad hoc networks is based on the ECDSA algorithm for supporting the authentication mechanism...
In vehicular ad hoc networks (VANETs), the malicious messages and tampered messages threat other drivers' life or confuse the traffic order possibly. The anonymity has to be traceable when the law enforcement authority wants to figure out the accountabilities about the anonymity. We describe the problem that characterizes the privacy of VANETs and proposes a new anonymous key mechanism with a system...
Vehicular ad hoc networks (VANETs) are promising approach for 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.Effective and robust solutions for addressing security and privacy issues are critical for the wide-spread adoption...
