Secure protocol for ad hoc transportation system

Abstract—We define an ad hoc transportation system as one that has no infrastructure such as roads (and lanes), traffic lights etc. We assume that in such a system the vehicle are autonomic and can guide and direct themselves without a human driver. In this paper we investigate how a safe distance can be maintained between vehicles. A vehicle which has been compromised by an adversary can cause serious chaos and accidents in such a network (a denial of service type of attack). A simple key management scheme is then introduced to ensure secure communications between the components of the system. Keywords–collision avoidance, cyber-physical systems, secure communications I

Implementation of Efficient Cooperative Message Authentication for Vehicular Ad-Hoc Networks

Vehicular Ad-Hoc Network(VANET) is a potential area in research field to bestow Intelligent Transportation System (ITS) services to the end users. It is a exigent topic for its high mobility and frequent network distraction. Lately researchers are carrying out task on many specific issues related to VANET like routing, broadcasting, Quality of Service (QoS), security, architectures, applications, protocols, etc. The augment in vehicles in today’s life has lead to brutal road accidents and traffic jam in urban areas. One of the solution to this problem could be a means of communication between the vehicles for safety. Safety measures lack these days in VANET as malicious drivers in the network disrupt the system routine. In this paper , a new location Based Secure Routing Protocol( PBSRP) which is a hybrid of Most Forward within Radius and Border Node based Most Forward within Radius (B-MFR) routing protocols. A module for security is implemented in this protocol using station to station key agreement protocol for preventing system from several attacks. The module goes through three phases: initialization phase, optimal node selection phase and secure data delivery phase. The outcome of Simulation imparts that PBSRP has better performance than MFR in terms of end to end delay and packet delivery ratio when malicious drivers are included in the network

A Contribution to Secure the Routing Protocol "Greedy Perimeter Stateless Routing" Using a Symmetric Signature-Based AES and MD5 Hash

This work presents a contribution to secure the routing protocol GPSR (Greedy Perimeter Stateless Routing) for vehicular ad hoc networks, we examine the possible attacks against GPSR and security solutions proposed by different research teams working on ad hoc network security. Then, we propose a solution to secure GPSR packet by adding a digital signature based on symmetric cryptography generated using the AES algorithm and the MD5 hash function more suited to a mobile environment

MobileTrust: Secure Knowledge Integration in VANETs

Vehicular Ad hoc NETworks (VANET) are becoming popular due to the emergence of the Internet of Things and ambient intelligence applications. In such networks, secure resource sharing functionality is accomplished by incorporating trust schemes. Current solutions adopt peer-to-peer technologies that can cover the large operational area. However, these systems fail to capture some inherent properties of VANETs, such as fast and ephemeral interaction, making robust trust evaluation of crowdsourcing challenging. In this article, we propose MobileTrust—a hybrid trust-based system for secure resource sharing in VANETs. The proposal is a breakthrough in centralized trust computing that utilizes cloud and upcoming 5G technologies to provide robust trust establishment with global scalability. The ad hoc communication is energy-efficient and protects the system against threats that are not countered by the current settings. To evaluate its performance and effectiveness, MobileTrust is modelled in the SUMO simulator and tested on the traffic features of the small-size German city of Eichstatt. Similar schemes are implemented in the same platform to provide a fair comparison. Moreover, MobileTrust is deployed on a typical embedded system platform and applied on a real smart car installation for monitoring traffic and road-state parameters of an urban application. The proposed system is developed under the EU-founded THREAT-ARREST project, to provide security, privacy, and trust in an intelligent and energy-aware transportation scenario, bringing closer the vision of sustainable circular economy
