With the development of intelligent transport systems (ITS) and vehicular ad hoc network (VANET), vehicular cloud computing (VCC) has been proposed to bring essential and potential benefits, such as improving traffic safety and offering computational services to road users. To make such computational services reliable and secure, the computation results from the vehicular cloud (VC) should be verifiable...
As one of the essential components of Intelligent Transport Systems (ITS), Vehicular Ad Hoc Network (VANET) plays a significant role in enabling various on-road applications, most of which primarily rely on two-top Vehicle-To-Vehicle communications. To make such communications reliable and secure, it is significant to ensure that the trustworthy vehicles are selected as relays. To tackle this challenge,...
In this paper, to simultaneously protect the receiver-location privacy and improve the performance of packet delivery in VANET, we utilize ``Sacrificing the Plum Tree for the Peach Tree" - one of the Thirty-Six Strategies of Ancient China, to propose a socialspot-based packet forwarding (SPF) protocol, where each vehicle receiver only reveals a non-sensitive socialspot, e.g., a shopping mall,...
Vehicle chatting is one of the most promising applications in VANETs, which allows like-minded vehicles to chat on the topics of common interest on the road. However, there exist some newly emerging privacy challenging issues in vehicle chatting application, such as how to find a like-minded vehicle on the road and how to prevent one's interest privacy (IP) from others who are not like-minded? In...
Roadside Units (RSUs) aided distributed certificate service is a promising approach for ensuring security and privacy preservation in vehicular ad hoc networks (VANETs), where the existence of RSUs is critical for such a scheme in order to allow On-Board Units (OBUs) to update their short-time certificates on time. However, RSUs may only be deployed at some critical points along roads due to the cost...
To achieve efficient authentication on emergency events in vehicular ad hoc networks, we introduce a novel aggregated emergency message authentication (AEMA) scheme to validate an emergency event. We make use of syntactic aggregation and cryptographic aggregation techniques to dramatically reduce the transmission cost, and adopt batch verification technique for efficient emergency messages verification...
With the adoption of state-of-the-art telecommunication technologies for sensing and collecting traffic related information, Vehicular Sensor Networks (VSNs) have emerged as a new application scenario that is envisioned to revolutionize the human driving experiences and traffic flow control systems. To avoid any possible malicious attack and resource abuse, employing a digital signature scheme is...
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...
