Vehicular ad hoc networks (VANETs) are being designed to convenience traffic, keep safety and provide services to drivers. To meet this goal, the vehicles involved should be trustworthy which eagerly needs valid V2V, V2I, I2V authentication. As to the authentication models used in VANETs, many organizations and research centers have done lots of work. The latest authentication models used in VANETs...
In this paper we propose a four-stage design approach towards securing a VANET architecture with an improved PKI structure. The new PKI structure helps in keeping the users autonomous, whilst achieving the security alongside. Communication between the central certificate authority is minimized by employing self authorization by the users. This is attained by self generation of pseudonyms. This scheme...
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...
The current research on privacy assurance in vehicular ad hoc networks (VANETs) by pseudonym generation and network accountability through revocation has not achieved the desired results. Our research has identified the problems associated with the current techniques. We have revisited the pseudonym generation concept to address the privacy need of the network. In order to improve the efficiency of...
