The software running on electronic devices is regularly updated , these days. A vehicle consists of many such devices, but is operated in a completely different manner than consumer devices. Update operations are safety critical in the automotive domain. Thus, they demand for a very well secured process. We propose an on-board security architecture which(More)
Vehicle testing and diagnosis requires huge amounts of data to be gathered and analyzed. Not all possibly interesting data can be stored because of the limited memory available in a tested vehicle. On-board preprocessing of data and decisions about which information has to be kept or omitted is thus vital for vehicle testing routines. This paper introduces(More)
—The effectiveness of Car2X communication strongly relies on trust in received data. Securing in-vehicle communication is an essential yet so far overlooked step to achieve this objective. We present an approach based on the use of symmetric key material protected with inexpensive hardware. We modeled the involved cryptographic and network protocols, showed(More)
Mobile devices such as smartphones have gained more and more attention from security researchers and malware authors, the latter frequently attacking those platforms and stealing personal information. Vehicle on-board networks, in particular infotainment systems, are increasingly connected with such mobile devices and the internet and will soon make it(More)
This paper introduces a method for selectively pre-processing and recording sensor data for engineering testing purposes in vehicles. In order to condense data, methodologies from the domain of sensor networks and stream processing are applied, which results in a reduction of the quantity of data, while maintaining information quality. A situation-dependent(More)
—Modern automobiles are increasingly connected to the world and integrate always more electronic components managing simultaneously infotainment and safety functions. Much more than just a simple transportation mean, the car is now customizable and like current smartphones, it will soon allow to load and install third-party applications directly from the(More)
