Abstract-Efficient schemes for warning message dissemination in vehicular ad hoc networks (VANETs) use context information collected by vehicles about their neighbor nodes to guide the dissemination process. Based on this information, vehicles autonomously decide whether or not they are the most appropriate forwarding nodes. These schemes maximize their performance when all the vehicles advertise correct information about their positions. Position errors introduced by nodes attacking the system, and other common errors due to malfunction of the localization systems, may drastically reduce the performance of the dissemination process. We present a proactive Cooperative Neighbor Position and Verification (CNPV) protocol that detects nodes advertising false locations and selects optimal forwarders so as to mitigate the impact of adversarial users. We combine our mechanism with two warning dissemination schemes for VANETs, and demonstrate how these algorithms can benefit from the use of our security scheme in the presence of malicious nodes trying to exploit the inherent vulnerabilities of each algorithm.

“…Future positioning systems will offer authentication services, e.g., as is the case for the upcoming Galileo system. Moreover, schemes like those described in [36] can detect spoofed replayed signals and prevent nodes from utilizing a time and location reference that is under the adversary's control.…”

Abstract-The characteristics of vehicular communication environments and their networking and application requirements have led to the development of unique networking protocols. They enable vehicle-to-vehicle and vehicle-to-infrastructure communication based on the IEEE 802.11 technology, ad hoc principles, and wireless multihop techniques using geographical positions. These protocols, which are commonly referred to as Geocast, greatly support the vehicular communication and applications but necessitate a tailored security solution that provides the required security level with reasonable processing and protocol overhead, as well as reasonably priced onboard and road-side unit equipment. In this paper, we present the design of a security solution for Geocast, which is based on cryptographic protection, plausibility checks using secure neighbor discovery and mobility-related checks, trustworthy neighborhood assessment, and rate limitation. We analyze the achieved security level of the proposed scheme and assess its overhead and performance. Furthermore, we develop a software-based prototype implementation of a secure vehicular communication system. We find that the proposed security measures could result in a network performance bottleneck in realistic vehicular scenarios. Finally, we analyze the tradeoff between security overhead and protocol performance and determine the minimal processing overhead needed for acceptable performance.
