In recent years, the field of networking has been marked by the emergence of a new technology that seems poised to revolutionize our infrastructures. Software-Defined Networks (SDN) introduce a novel networking paradigm characterized by a distinct architectural philosophy. This evolution in network infrastructure streamlines equipment and fosters independence among devices. Rather than denoting a specific solution or product, SDN encompasses a collection of innovative technologies designed to facilitate centralized management of network resources, enhance programmability and orchestration, and enable virtualization. SDN has emerged as a critical technology for overseeing large-scale networks, including vehicular networks. Its foundation lies in the physical separation of the control plane from the data plane, allowing for logically centralized control and intelligence through a software controller. Recently, several studies have shown that integrating the SDN paradigm into Vehicular Ad Hoc Networks (VANETs) provides flexibility, programmability, and better scalability support. This paper presents a thorough review of security issues for SDN-based vehicular VANETs, offering a detailed analysis of architectural considerations and security services across different network layers, while also highlighting emerging research challenges for future investigation.

摘要

In recent years, the field of networking has been marked by the emergence of a new technology that seems poised to revolutionize our infrastructures. Software-Defined Networks (SDN) introduce a novel networking paradigm characterized by a distinct architectural philosophy. This evolution in network infrastructure streamlines equipment and fosters independence among devices. Rather than denoting a specific solution or product, SDN encompasses a collection of innovative technologies designed to facilitate centralized management of network resources, enhance programmability and orchestration, and enable virtualization. SDN has emerged as a critical technology for overseeing large-scale networks, including vehicular networks. Its foundation lies in the physical separation of the control plane from the data plane, allowing for logically centralized control and intelligence through a software controller. Recently, several studies have shown that integrating the SDN paradigm into Vehicular Ad Hoc Networks (VANETs) provides flexibility, programmability, and better scalability support. This paper presents a thorough review of security issues for SDN-based vehicular VANETs, offering a detailed analysis of architectural considerations and security services across different network layers, while also highlighting emerging research challenges for future investigation.
