The number of on-road vehicles has increased by almost 140% over the past decade, thereby increasing pollution levels, congestion and fuel consumption. To contain such a situation, Vehicular Ad-Hoc Network (VANET) technology is almost on the verge of large scale practical deployment. Hence, the aim is to provide a system to control the above using VANET and to provide an infrastructure to reduce the...
Detecting malicious and selfish nodes is an important task in Vehicular Adhoc NETworks (VANETs). Various proposals adopted trust management as an alternative solution for it is less costly in terms of computation delay and mobility adaptation, compared to the cryptography-based solutions. However, the existing solutions assume that in general the attackers have always a dishonest behavior that persists...
Enhancing road safety is the main goal of Vehicular Adhoc Networks (VANETs). However, the assumption that all peers are honest, cooperative can lead to catastrophic situations. To deal with such misbehaving peers, trust establishment can be used to enhance the security without affecting network performance. In this paper, we propose an opportunistic alert dissemination mechanism based on the trust...
Vehicular Ad-hoc Network (VANET) is a sub class of mobile ad-hoc networks. VANET provides wireless communication among vehicles and vehicle to road side equipments. The communication between vehicles is used for safety, comfort and for entertainment as well. The performance of communication depends on how better the routing takes place in the network. The life saving factor is also the key issue in...
Localization and exchanged position information plays a big role in Vehicular Ad-Hoc Networks (VANET). Several network services and applications, such as safety messages, require location information. The data are exchanged between vehicles within their radio communication range. In real life implementation, direct communication can be interfered and blocked by obstacles on the road preventing two...
Vehicular Ad-Hoc Networks (VANETs) have the potential to optimize traffic in modern urban areas, reduce congestions and pollution, and increase passenger safety and comfort. Applications designed for such networks pose new security constraints. The mobile devices have limited resources to spare, and the network connectivity is reduced because of the mobility of cars. We present a security protocol...
Automotive networking on US highways is moving into high gear. Smart cars, connected vehicles, intelligent transportation systems (ITS), vehicular ad-hoc networks (VANET), and vehicle telematics represent parallel and overlapping technologies and services that will define the future of the American roadway systems. The integration of computing technology and expanding communication services is driving...
In this paper, we present a novel security solution known as global public key algorithm based on bilinear pairing cryptography concept, for location service in vehicular ad-hoc networks (VANETs). Indeed, many geographic routing protocols used in VANET need location service for obtaining destination position. The location service makes way for major security concern in VANETs. We design an efficient...
Recently, Vehicular Ad-hoc Networks (VANETs) employing a combination of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) wireless communication have been proposed to alert drivers about different traffic events. NOTICE, a secure and privacy-aware architecture for the Notification Of Traffic InCidEnts that provides drivers with up-to-the-minute notification about highway conditions, is...
This paper proposes a security framework with strong non-repudiation and privacy using new approach of ID-based cryptosystem in VANETs. To remove the overheads of certificate management in PKI, security frameworks using an ID-based cryptosystem are proposed. These systems, however, cannot guarantee strong non-repudiation and private communication since they suffer from the inherent weakness of an...
In this paper, we propose a robust and efficient signature scheme for vehicle-to-infrastructure communications, which can effectively eliminate the performance bottleneck when verifying a mass of signatures within a rigorously required interval, even under adverse scenarios with bogus messages. In addition, our scheme offers the other conventional security features for vehicular networks, such as...
Communication using VANETs is commonly seen as the next milestone for improving traffic safety. Vehicles will be enabled to exchange any kind of information that helps to detect and mitigate dangerous situations. Security research in the past years has shown that VANETs are endangered by a plethora of severe security risk. Subject of this work is the modeling of attackers that target active safety...
