Securing Warning Message Dissemination in VANETs Using Cooperative Neighbor Position Verification

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.

Social Internet of Vehicles for Smart Cities

“…Positive entity behaviour is recorded in positive reputation systems, and negative entity behaviour is recorded in negative reputation systems [105]. The authors in [112] present a cooperative neighbour position verification mechanism based on V2V communications among vehicles; it can mitigate the impact of adversary users by excluding malicious nodes from the packet routing mechanism. The aim of the reputation system in the SIoV is to establish trust values for each entity in the SIoV, providing information for other entities to make trust-based decisions.…”

Multi-hop broadcast message dissemination in vehicular ad hoc networks: A security perspective review

“…In order to perform a reliable calculation, position of both sender and receiver must be verified with mechanisms such as the ones presented in Barnwal and Ghosh, 65 Fogue et al, 66 Monteiro et al, 67 Yan et al, 68 and Zhang et al 69 For instance, Yan et al 68 and Monteiro et al 67 propose the use of multiple antennas to detect vehicles spoofing their claimed location. The main idea is to use the measured received signal strength (RSS) at each directional antenna, which changes in accordance with the angle it forms with the vehicle.…”

“…Note that for receiver-oriented broadcast dissemination protocols that do not consider the periodic exchange of beacons (e.g. Wisitpongphan et al 7 ), solutions like the one presented in Fogue et al 66 could be adapted to use the disseminated message instead of the exchanged beacons.…”

“…The periodic exchange of beacon messages in senderoriented broadcast dissemination protocols can be exploited to implement data-centric security solutions. 66,77,85 For instance, in Jaballah et al, 47 a cooperative position verification mechanism, based on the exchange of an active neighbors table, is proposed to secure the broadcast dissemination process.…”

TrAD: Traffic Adaptive Data Dissemination Protocol for Both Urban and Highway VANETs

“…It assigns a shorter rebroadcast delay to the vehicle located at an intersection, which intends to disseminate data message in more directions. However, Fogue et al [11] pointed out that eMDR and UV-CAST should not blindly trust the GPS positioning that is usually not accurate. Thus, the impact of GPS drift on the performance of protocols should be evaluated.…”
