The past decade has witnessed a growing interest in vehicular networking and its panoply of potential applications among vehicles. Olariu and his co-workers [1, 2, 3] have put forth the vision of a new type of cloud, Vehicular Cloud Computing (VCC). It is clear that the VCC concept raise exceptional security and privacy challenges. It is also clear that if the VCC concept is to see a wide adoption...
Last few years, vehicular network has been taken more attention of researchers and automotive industries due to life saving factor. Vehicular Ad hoc Network (VANET) needs security to implement the wireless environment and serves users with safety and non safety applications. Attackers generate different attacks in this life saving vehicular network. In this paper, we propose five different classes...
For increasing safety of driving, intelligent vehicles in vehicular ad hoc networks (VANETs) communicate with each other by sending announcements. The existence of a system that guarantees the trustworthiness of these announcements seems necessary. The proposed approach generating announcements should be preserved from internal and external attackers that attempt to send fake messages. In this paper,...
Message authentication, to ensure the receiving message is true and coming from the claimed source, is a key issue in vehicular ad hoc network (VANET) because the message may be life-critical, traffic information, or emergence message transmitted by the strange sources. Due to the nature of realtime and high mobility in VANET message, the traditional PKI security schemes are not suitable for VANET...
Vehicular ad hoc network (VANET) is a promising technology for providing safer roads and a more efficient driving experience. However, the deployment of VANETs is dependent on several issues in security and privacy. In this paper, a trust-based privacy-preserving model for VANETs is presented. The model is unique in its ability to protect privacy while maintaining accurate reputation-based trust....
Vehicular ad hoc networks support a wide range of promising applications including vehicular sensing networks, which enable vehicles to cooperatively collect and transmit the aggregated traffic data for the purpose of traffic monitoring. The reported literatures mainly focus on how to achieve the data aggregation in dynamic vehicular environment while the security issue especially on the authenticity...
Due to their nature, vehicular ad hoc network (VANET) is vulnerable to denial of service (DoS) attacks, such as jamming attack. The objective of a jammer is to interfere with legitimate wireless communications, and to degrade the overall QoS of the network. In this paper, we propose a model to detect a particular class of jamming attack, in which the jammer transmits only when valid radio activity...
Vehicular communications by means of exchanging safety message considerably reduces life and property damage. So securing this message is essential. In this paper, we focus on protocols based on a fixed key infrastructure that establish stronger security in comparison with dynamic structures. These protocols have some problems in terms of implementation issues. In effect, a very important issue is...
In any vehicular adhoc network, there is always a possibility of incorrect messages being transmitted either due to faulty sensors and/or intentional malicious activities. Detecting and evicting sources of such misbehavior is an important problem. We observe that the performance of misbehavior detection schemes will depend on the application under consideration and the mobility dynamics of the detecting...
Vehicular Ad Hoc network (VANET) can offer various services and benefits to VANET users and thus deserves deployment effort. Misusing such network could cause destructive consequences. It is therefore necessary to discourage misbehavior and defend VANET systems against it, in order to ensure correct and smooth operations of the network. In this paper, we propose a defense technique to handle misbehavior...
