Abstract: IEC 61499 is an open standard based on function blocks applied for distributed automation solutions. In this paper we discuss the application of IEC 61499 for designing and implementing event-based Smart Grid applications. We show that IEC 61499 is well suited in the context of Smart Grids at the example of the concrete use case of power exchange between several peers of the Smart Grid. The feasibility of IEC 61499 in the context of this use case is assessed on the basis of a prototypical implementation using the open source framework 4DIAC. We conclude that IEC 61499 is a powerful tool for engineering event-based Smart Grid applications.

Vehicle-to-vehicle communication is a key technology for achieving increased perception for automated vehicles, where the communication enables virtual sensing by means of sensors in other vehicles. This paper presents a trust system that allows a cooperative and automated vehicle that uses V2V communication to make more reliable and safe decisions. Read more.

This paper is an experience report of team Halmstad from the participation in a competition organised by the i-GAME project, the Grand Cooperative Driving Challenge 2016. The competition was held in Helmond, The Netherlands, during the last weekend of May 2016. We give an overview of our car’s control and communication system that was developed for the competition following the requirements and specifications of the i-GAME project. Read more.

We describe open problems that need to be addressed in a prospective security framework for the automotive domain. Based on a study of several safety and security standards from other areas as well as suggested automotive security models, we propose an appropriate representation of security levels which is similar to, and will work in parallel with traditional safety, and a method to perform the mapping to a set of predefined system requirements, design rules and security mechanisms.

We first suggest that the risk assessment process should result in five security levels. Further, we identify suitable security mechanisms and design rules for automotive system design and associate them with appropriate security levels. Our proposed methodology is as much as possible aligned with ISO 26262 and we believe that it should therefore be realistic to deploy in existing organizations. Read more.

In this thesis we study various safety and security standards and proposed frameworks from different industrial domains with respect to their way of classifying demands in the form of levels and their methods to derive requirements. In our proposed framework, we suggest security levels appropriate for automotive systems and continue with a mapping between these security levels and identified security mechanisms and design rules to provide basic security. We further study in detail a mechanism which provides freshness to authenticated messages, namely AUTOSAR SecOC Profile 3, and present a novel extension that offers a faster synchronisation between ECUs and reduces the number of required messages for synchronisation.

We analyse AUTOSAR SecOC Profile 3, a solution to provide freshness for authenticated messages, and further propose an extension of this security profile that copes with the limitations identified in our analysis. The extended profile provides a faster resynchronisation of the freshness value and consumes less bandwidth due to the reduction of the number of synchronisation messages needed. We evaluated our solution based on two demonstrators, one communicating via CAN bus and one communicating over Ethernet. Read more.
