A New Framework for Secure Routing in VANET

2018

Background and Objectives: Vehicular Ad-Hoc Networks can enhance road safety and enable drivers to avoid different threats. Safety applications, mobile commerce, and other information services are among different available services that are affected by dynamic topology, vehicle's speed and node misbehaving. Dynamic topology makes the route unstable and unreliable. So, improving the throughput and performance of VANET through reliable and stable routes with low overhead are among the important goals in this context. Methods: Verifying all issues related to the reliable routing, different effective internal, external and environmental factors on route reliability are led to a new security framework in this paper. Black-hole attack and its effects, as the most well-known attack in wireless networks, along with presenting a secure routing protocol are other achievements of this paper. The proposed protocol uses a trust management system to detect and neutralize this type of attack. Results: Simulation results show that the presented trust-based framework can increase the reliability of the networks by decreasing the effect of the malicious nodes in the routing process. Conclusion: Our simulation results show that the proposed protocol can overcome the effects of black-hole attackers and it can increase throughput by 93% and packet received rate by 94.14% compared to the original AODV. Investigating the effect of the other attacks, simulating in an urban area with repetitive communications and considering the RSU in verifying the trustworthiness of entities are suggested for our future works.

An Individual Trust Management Technique for Mitigating Security Attack in VANET

The key issues of VANETs are routing and security. A secure routing environment provides a better efficiency in terms of data packet delivery and minimizing bit error rate. The information passed through one vehicle for another vehicle must reach on time to prevent the second vehicle from any accident. The message passing system may get affected due to malicious interpretation in the network. In this we establish an efficient routing work which dynamically nodes itself. If it meets any intrusion in the network according to its fitness value designed so that the message passed to the second vehicle reaches on time. We design and implemented a dynamic routing protocol for the successful delivery of the time messages from one vehicle to another and also enhanced the performance of security by implementing a message interchange API system. The parameters which are evaluated given as throughput, error rate, and packet delivery rate.

Trust Based Approaches for Secure Routing in VANET: A Survey

Vehicular Ad-hoc networks (VANETs) require trusted vehicles to vehicles communication. VANET is multidimensional network in which the vehicles continuously change their locations. Secure routing is imperative during the routing process to incorporate mutual trust between these nodes. Sometimes, the malicious node broadcast the bogus information among other nodes. Establishing trust is a challenge while one or more malicious nodes attempt to disrupt route discovery or data transmission in the network. A lot of research has been carried out for secure routing process with trust-based approaches. In this paper, we present survey of various mechanisms to improve different ad-hoc routing protocols for secure routing process by enhancing the trust among different nodes in VANETs.

Enhancement of Security in VANET by Detection of Malicious Nodes Using Trust System

Vehicular ad-hoc network (VANET) is one of the recent and promising technologies to revolutionize the transportation system where vehicles can communicate by exchanging messages via wireless medium. It has received a lot of interest in the last few years. But still there are many issues that need to be resolved for its betterment and use in the transportation system. Though, security is of major concern whenever we talk about communication between entities in a network, therefore it needs to be addressed perfectly. This paper present a security enhancement which when deployed will produce efficient results in the detection and prevention of malicious nodes in the system. With the detection of malicious nodes in the system, we will reduce the risk by selection of the trusted nodes and hence will increase system availability.

Trust-Based Distributed Authentication Method for Collision Attack Avoidance in VANETs

IEEE Access

A vehicular ad hoc network (VANET) is a collection of mobile vehicles that aids roadside communication through vehicle-to-vehicle and vehicle-to-infrastructure operation modes. The network is autonomous and, hence, requires a wide range of security measures to protect its communications from attack. Recent studies on VANET security have focused on resolving the issues due to computation and distribution density of the vehicles. Probability distribution measures have been administered for detecting collision attacks, which increases the computational complexity. In this paper, a trust-based distributed authentication (TDA) method that relies on a global trust server and vehicle behavior for avoiding collision attacks is proposed. This method ensures both inter-vehicular and intra-vehicular communication security in the network. In addition, a channel state routing protocol (CSRP) is proposed to improve the communication reliability among the vehicles. Reliable vehicles are identified according to the on-board unit (OBU) energy and the channel state of the vehicle to deliver seamless communication. The biased methods are assimilated to improve the communication reliability by avoiding collision attacks and improving secured packets flow in VANETs. In particular, the CSRP minimizes the energy exploitation of OBUs and time delay. TDA improves the security of the network by improving the collision recognition rate and the broadcast rate. INDEX TERMS Vehicular ad-hoc networks, mobile ad-hoc networks, collision attacks, trust hash-based, channel state routing protocol. I. INTRODUCTION Vehicular ad-hoc networks (VANETs) are the foundation of next-generation intelligent transportation systems (ITSs), which are a subset of mobile ad-hoc networks (MANETs). MANETs aim to provide inter-vehicle communication and roadside-to-vehicle communication to increase the safety and efficiency of roads by providing precise and useful data to drivers and road specialists [1], [2]. VANETs aim to enhance wide variety of applications, including road and security applications, for example, notifications of traffic congestion, emergency notifications, and peer-to-peer communications for sharing information. Performing channel estimation and the according routing can significantly improve VANETs [3]. According to the various applications, VANETs have been used to create intelligent systems through vehicle-to-vehicle (V2V) communication [4]. This vehicle-based communication process relies on the density of receivers and actions. From the obtained vehicle communication, the VANET manages the roadside unit (RSU) used to transmit information from one vehicle to another.

International Journal of Future Generation Communication and Networking, 2016

Vehicular Ad Hoc Network (VANET) is a more influential network in which vehicles depend on each other to communicate and for the secure exchange of the messages. With the improvement in the technology, mainly the vehicles are equipped with Wi-Fi and GPS devices to improve the traffic handling and road safety. But many vehicles may broadcast the bogus messages for their own purpose, so it needs a trustful environment and an effective trust management schemes to prevent the network from the various malicious attacks. Trust establishment is very challenging as the network is highly mobile and vehicles may come in or depart at any time. In this paper, we first discuss the VANET model to describe the environment, and then the trust management schemes to secure the network and lastly the various cryptography fundamentals for the fast and safe message transfer.

ART: An Attack-Resistant Trust Management Scheme for Securing Vehicular Ad Hoc Networks

—Vehicular ad hoc networks (VANETs) have the potential to transform the way people travel through the creation of a safe interoperable wireless communications network that includes cars, buses, traffic signals, cell phones, and other devices. However, VANETs are vulnerable to security threats due to increasing reliance on communication, computing, and control technologies. The unique security and privacy challenges posed by VANETs include integrity (data trust), confidentiality, nonrepudiation, access control, real-time operational constraints/demands, availability, and privacy protection. The trustworthiness of VANETs could be improved by addressing holistically both data trust, which is defined as the assessment of whether or not and to what extent the reported traffic data are trustworthy, and node trust, which is defined as how trustworthy the nodes in VANETs are. In this paper, an attack-resistant trust management scheme (ART) is proposed for VANETs that is able to detect and cope with malicious attacks and also evaluate the trustworthiness of both data and mobile nodes in VANETs. Specially, data trust is evaluated based on the data sensed and collected from multiple vehicles; node trust is assessed in two dimensions, i.e., functional trust and recommendation trust, which indicate how likely a node can fulfill its functionality and how trustworthy the recommendations from a node for other nodes will be, respectively. The effectiveness and efficiency of the proposed ART scheme is validated through extensive experiments. The proposed trust management theme is applicable to a wide range of VANET applications to improve traffic safety, mobility, and environmental protection with enhanced trustworthiness.

Currently, serious investigations are made now in road security as a critical research domain. However, the majority of them are based on expensive infrastructure. In this paper, we propose a new scheme for warnings spreading between vehicles without any dependence on road foundation. A new concept of Active vehicle that combines the power of the intelligence ambient and the V2V technologies is introduced. For alert endorsement, we suggest a new model for trust management for VANET based on only the cooperation between "Active vehicles" in order to enhance their security states and to cut with the spread of false warnings through a vehicular network.
