Abstract

The Vehicular ad-hoc networks (VANET) are a subclass of MANET with vehicles as mobile nodes. The vehicles exchange data via vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communication. The securities of data communications focus on deciding data trust. The concept of trust estimates the reliability of communications data. In particular, we have mainly focused on problems of mistrust or data trust in the VANET network. In this paper, we will study some models of trust and compare them, which will help to reduce the impact of trust problem and try to improve it.

Highlights

Entity-oriented trust modelThe vehicle ad hoc network (VANET) is composed of the mobile entity called vehicle and fixed entity known as Road Side Units (RSUs)
The security of the communication concentrates about trust in data exchange during communication, which is based on the concept of trust model to improve the security of communication
The trust management has been proposed in the last years as an accurate alternative to deal with some security threats in highly distributed and dynamic scenarios

Summary

Introduction

The vehicle ad hoc network (VANET) is composed of the mobile entity called vehicle and fixed entity known as Road Side Units (RSUs). The VANET intelligent applications depend on the exchange of messages between the entities source and destinations [2]. These messages confront challenges evaluation trust of the data and entity to obtain insufficient attention. The security of the communication concentrates about trust in data exchange during communication, which is based on the concept of trust model to improve the security of communication. These trust models face some challenges must be considered against malicious vehicle that leads to the most critical and challenging security issues. The trust value obtained in the non-malicious environment will always be greater than the trust value obtained in the malicious environment [6-7]
