"Vehicle-to-Grid" (V2G) power will be a new green energy scheme in which electric or plug-in hybrid vehicles communicate with the Smart Grid to sell demand response services by either delivering electricity into the grid or by throttling their charging rate. Due to high vehicular speed, sporadic connection, limited communication range, and large volume of data that need to be transmitted,...
In this paper, a privacy-preserving chatting scheme is proposed to secure vehicular communication and achieve user privacy preservation in vehicular peer- to-peer networks. In specific, we first introduce identity-based-encryption technique which can protect the confidentiality of chatting content. Furthermore, to preserve user privacy, our scheme employs ring signature technique, which not only provides...
In this paper, we propose a mutual authentication and key agreement scheme for V2I communications. Our scheme improves security and privacy protection compared with the existing protocols. We consider common driver's tendency to design a more efficient scheme. The results of the security and performance analysis show that our scheme is suitable for practical use in terms of security, privacy, and...
Vehicular Ad hoc Network (VANET) is a network of vehicles on the roads, of which the success of its applications is highly dependent upon the underlying security mechanism. The default trial asymmetric PKI/ECDSA security mechanism is known for its high computational cost, thus lacking applicability in life-critical safety messaging. Alternative security schemes, such as symmetric methods provide faster...
Roadside units (RSUs) aided certificate service is a promising approach for ensuring security and privacy preservation in vehicular ad hoc networks (VANETs). In existing approaches, a vehicle can update certificate only when it passes by RSUs, however, this is impractical in many scenarios. Consequently, if there are no RSUs on the original driving trip, drivers have to adjust routes which means wasting...
Vehicular ad hoc networks get increased attention by vehicle manufacturers and researchers. Their deployment requires that security and privacy issues be resolved, particularly since they rely on wireless communication. In this paper, we propose a TPM-based security architecture, where TPM are embedded in vehicles. We emphasize the management of cryptographic keys needed for security and anonymity...
Vehicular communication systems (VCS) are becoming a cornerstone of modern intelligent transport systems. By enabling vehicles to communicate with each other via inter-vehicle communication as well as with roadside units via roadside-to-vehicle communication, vehicular networks will contribute to safer and more efficient roads by providing timely information to drivers and concerned authorities. This...
In recent years, there has been a tremendous increase in the usage of IT based systems in vehicles, with predictions that in the near future, more than 90% of innovations in the automotive sector will be centered on IT software and hardware. However, innovation also means that intellectual property (IP) is created, which is valuable to third (potentially) untrusted and malicious parties. In particular,...
Vehicular networks create a new communication paradigm that enables to exploit the movement of cars to disseminate content. If network coding is used, vehicles have much more flexibility in content sharing and the system stability and scalability are promoted also in presence of mobility. Along this line, we propose an efficient mechanism to provide secrecy of the information. Traditional approaches...
In this paper, we introduce an efficient conditional privacy preservation (ECPP) protocol in vehicular ad hoc networks (VANETs) to address the issue on anonymous authentication for safety messages with authority traceability. The proposed protocol is characterized by the generation of on-the-fly short-time anonymous keys between on-board units (OBUs) and roadside units (RSUs), which can provide fast...
