    • 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.

    • Timo Häckel. Service Classification in Service-Oriented ICT Architectures of Future Vehicles - Hauptseminar. Jul. 2017,
      [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. To design such a middleware it is important to know which services will communicate and what their requirements are. Therefore, this paper provides classification criteria for automotive services. Building on these criteria we describe a meta-data based approach to manage service communication via a middleware.

      [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.
