Abstract: The advent of rapid technological progression in today's world has paved way to a plethora of research areas in the field of Intelligent Transportation Systems (ITS) and Smart Driver-less vehicles. The need for provisioning the most optimized path for vehicles is essential in time-critical scenarios and Vehicular Ad-Hoc networks (VANET) provide a scalable framework for the same. Securing the flow of information and communication resources is of utmost importance in such dynamic networks and implementing it becomes challenging due to resource constraints and its operation in open public networks. In this paper, the architecture, routing and security issues of VANETs are discussed along with simulation of security attack due to malicious nodes. We have proposed a framework using Software Defined Networking (SDN) and fog computing which shall incorporate a lightweight and semi-centralized implementation, thereby providing a solution to resource constraints and scalability issues.

TL;DR: The results of the evaluation show that DistBlockNet is capable of detecting attacks in the IoT network in real time with low performance overheads and satisfying the design principles required for the future IoT network.
Abstract: The rapid increase in the number and diversity of smart devices connected to the Internet has raised the issues of flexibility, efficiency, availability, security, and scalability within the current IoT network. These issues are caused by key mechanisms being distributed to the IoT network on a large scale, which is why a distributed secure SDN architecture for IoT using the blockchain technique (DistBlockNet) is proposed in this research. It follows the principles required for designing a secure, scalable, and efficient network architecture. The DistBlockNet model of IoT architecture combines the advantages of two emerging technologies: SDN and blockchains technology. In a verifiable manner, blockchains allow us to have a distributed peer-to-peer network where non-confident members can interact with each other without a trusted intermediary. A new scheme for updating a flow rule table using a blockchains technique is proposed to securely verify a version of the flow rule table, validate the flow rule table, and download the latest flow rules table for the IoT forwarding devices. In our proposed architecture, security must automatically adapt to the threat landscape, without administrator needs to review and apply thousands of recommendations and opinions manually. We have evaluated the performance of our proposed model architecture and compared it to the existing model with respect to various metrics. The results of our evaluation show that DistBlockNet is capable of detecting attacks in the IoT network in real time with low performance overheads and satisfying the design principles required for the future IoT network.

TL;DR: The design substantially guarantees a secure and trustworthy vehicular IoT environment with user privacy preserved and the numerical simulation results show that malicious vehicular nodes or messages can be well detected while the overhead and impact on the network performance are acceptable for large-scale scenarios.
Abstract: The modern intelligent transportation system brings not only new opportunities for vehicular Internet of Things (IoT) services but also new challenges for vehicular ad-hoc networks (VANETs). Apart from enhanced network performance, a practical and reliable security scheme is needed to handle the trust management while preserving user privacy at the same time. The emerging 5G mobile communication system is viewed as a prominent technology for ultra-reliable, low-latency wireless communication services. Furthermore, incorporating software-defined network (SDN) architecture into the 5G-VANET enables global information gathering and network control. Hence, real-time IoT services on transportation monitoring and reporting can be well supported. Both pave the way for an innovative vehicular security scheme. This paper investigates the security and privacy issue in the transportation system and the vehicular IoT environment in SDN-enabled 5G-VANET. Due to the decentralized and immutable characteristics of blockchain, a blockchain-based security framework is designed to support the vehicular IoT services, i.e., real-time cloud-based video report and trust management on vehicular messages. This paper explicitly illustrates the SDN-enabled 5G-VANET model and the scheduling procedures of the blockchain-based framework. The numerical simulation results also show that malicious vehicular nodes or messages can be well detected while the overhead and impact on the network performance are acceptable for large-scale scenarios. Through case studies and theoretical analysis, we demonstrate our design substantially guarantees a secure and trustworthy vehicular IoT environment with user privacy preserved.

Abstract: Vehicular communication networks is a powerful tool that enables numerous vehicular data services and applications. The rapid growth in vehicles has also resulted in the vehicular network becoming heterogeneous, dynamic, and large-scale, making it hard to meet the strict requirements, such as extremely latency, high mobility, top security, and enormous connections of the fifth-generation network. Previous studies have shown that with the increase in the application of Software-Defined Networking (SDN) on Vehicular Ad-hoc Network (VANET) in industries, researchers have exerted considerable efforts to improve vehicular communications. This study presents an exhaustive review of previous works by classifying them based on based on wireless communication, particularly VANET. First, a concise summary of the VANET structure and SDN controller with layers and details of their infrastructure is provided. Second, a description of SDN-VANET applications in different wireless communications, such as the Internet of Things (IoT) and VANET is provided with concentration on the examination and comparison of SDN-VANET works on several parameters. This paper also provides a detailed analysis of the open issues and research directions accomplished while integrating the VANET with SDN. It also highlights the current and emerging technologies with use cases in vehicular networks to address the several challenges in the VANET infrastructure. This survey acts as a catalyst in raising the emergent robustness routing protocol, latency, connectivity and security issues of future SDN-VANET architectures.

TL;DR: This paper proposes a trust management scheme based on hybrid cryptography (TMHC) to secure VANET to a larger extent and shows that the proposed scheme meets security requirements and performs effectively.
Abstract: Vehicular Ad hoc Networks (VANETs) are used to improve traffic management and reduce the number of road accidents by providing safety applications. However, VANETs are susceptible to a number of security attacks from malicious entities. To secure the network against these attacks, most of the researchers have proposed various security schemes based on cryptography and trust management. While both cryptography and trust management are effective to some extent, each scheme has some flaw to fully secure the network. In this paper, we propose a trust management scheme based on hybrid cryptography (TMHC) to secure VANET to a larger extent. As authentication is an integral part of trust establishment and secure communications between vehicles, the proposed TMHC integrates hybrid cryptography based authentication for efficient and robust trust management scheme. The hybrid cryptography includes, asymmetric identity-based (ID-based) digital signature and symmetric hash message authentication code (HMAC). The trusted road-side unit (RSU) evaluates trust-value, whereas, agent trusted authority (ATA) computes trust-value of vehicle based on its reward-points. The results are gained with extensive simulations to validate the proposed scheme. The results show that the proposed scheme meets security requirements and performs effectively. The communication overhead, computation overhead, storage overhead, and end-to-end delay of the proposed scheme were improved by 6% to 15%, 9% to 23%, 7% to 19%, and 4% to 15.85%, respectively, as compared to existing schemes.
