- Mehmet Cakir. Security with Software-Defined Networking in Automotive Networks - Forschungswerkstatt 1. Feb. 2021,
[Abstract], [Fulltext Document (pdf)], [Slides (pdf)], [Bibtex]Cars are constantly equipped with new functions and intelligence. As the car becomes more open to it's environment using Vehicle-to-Everything (V2X) communication technologies, the necessity of security requirements becomes apparent. The concept of Software-Defined Networking (SDN) promises to simplify the control over network flows and devices. This work shows the current state of automotive networks and their security requirements. Furthermore, the concept of SDN and security concepts of SDN are explained. Finally, expectations of the use of SDN in cars will be discussed.

- Sebastian Szancer. Concept of a V2X Application-Level Gateway with Context-sensitive Semantic Analysis of Application Data - Hauptprojekt. May. 2020,
[Abstract], [Fulltext Document (pdf)], [Bibtex]Modern cars communicate with a variety of entities ranging from other vehicles and infrastructure, such as traffic lights, to Internet-based services running on remote servers. This V2X communication enables the realisation of innovative functionality such as ''over the air'' ECU software updates, optimised navigation and route planning or coordinated autonomous driving. It is necessary that V2X communication is appropriately secured, especially since it includes safety-critical communication. This can be done with a V2X Security Gateway in the vehicle, which serves as a proxy for vehicle-internal services communicating with the outside world and ensures cryptographic security as well as security on the internet-, transport- and application layer. A central component of such a V2X Security Gateway is the V2X Application-Level Gateway, which ensures security on the application layer, including a context-sensitive semantic analysis of application data. It also realises the proxy-functionality and ensures cryptographic security. This paper presents a concept and prototype implementation of such a V2X Application-Level Gateway for IP-based traffic. The implementation was evaluated with the V2X Application-Level Gateway software run on an Intel NUC integrated in a test network representing an internal vehicle network. In this network, consisting of an Edgecore SDN switch and Intel NUCs and Raspberry Pis representing vehicle ECUs, the scenario of remotely controlling the vehicle trunk was simulated.

- Timo Häckel. A Middleware Solution for Open and Dynamic ICT Architectures in Future Cars - Hauptprojekt. Apr. 2018,
[Abstract], [Fulltext Document (pdf)], [Bibtex]The Information and Communication Technology (ICT) of today's vehicles is currently experiencing a major revision. With the introduction of a centralised communication medium and the Service-Oriented-Architecture (SOA) paradigm, the automotive industry adopts the challenges posed by connected cars and autonomous driving. In novel SOA based ICT architectures the communication middleware for services plays an important role, as it enables services to exchange messages. This paper names the key aspects of such a middleware and specifies our solution. We design a Service-Oriented Architecture based middleware that supports Quality-of-Service (QoS) policies to define the requirements on a connection. Finally, we describe our realisation in the simulation environment OMNeT++.

- Philipp Meyer. Simulation-based Evaluation of DoS Protection through Credit Based Metering in Time Sensitive Networking In-Car Networks. Nov. 2017,
[Abstract], [Fulltext Document (pdf)], [Bibtex]Ethernet is the most promising solution to reduce complexity and enhance the bandwidth in the next generation incar networks. The real-time aspects in such networks are becoming possible through special Ethernet protocols. On promising candidate is the IEEE 802.1 Time Sensitive Networking protocol suite. However, the common Ethernet technology increases the vulnerability of the cars infrastructure. In this paper an algorithm is proposed which on the one hand provide protection against DoS attacks on switches by metering incoming Ethernet frames. And on the other hand adapts to the behaviour of the Credit Based Shaping algorithm which was firstly standardized in the Time Sensitive Networking predecessor Audio/Video Bridging. A simulation of this proposed Credit Based Metering algorithm evaluates the concept.

Building on these criteria we describe a meta-data based approach to manage service communication via a middleware.

Service Classification in Service-Oriented ICT Architectures of Future Vehicles - Grundprojekt. May. 2017,
[Abstract], [Fulltext Document (pdf)], [Bibtex]Information and communication technology (ICT) is already a major driver in the automotive industry. Most of the new features and innovations over the past 10 years were enabled by ICT, still the usage of ICT in today's vehicles lacks behind it's possibilities. By introducing new service-oriented ICT architectures for future vehicles the industry tries to simplify the development and verification process as well as enabling Plug&Play capabilities in cars. As the current discussion shows, these new architectures will be built-on centralised computing units with high processing power using only one communication medium. Software components will be running as services inside and outside of the vehicular network. As this is a revolution in automotive software development, this paper gives an overview of the state of the art in research and industry regarding the design and deployment of novel ICT architectures. Based on this survey we extract the key attributes for service classification in the automotive domain and give an example on how to use this classification to control the communication between services, by arranging them accordingly.

[Abstract], [Fulltext Document (pdf)], [Bibtex]The increasing complexity of automotive networks and their high bandwidth requirements will demand new concepts in networking of electronic automotive components. TTEthernet is a suitable candidate to solve this problem. In order to allow testing of control units in an early point in the development process, cluster simulation has been established as an adequate manner and therefore in this project it is developed for Real-time Ethernet using the example of TTEthernet. In this work, hardware and topology setup approaches for a Real-time Ethernet based cluster simulation are explained. Furthermore, a formal model basing on set theory is presented, that allows for calculating suitable topologies in dependency of selected devices under test.
