Implementation of the simTD security architecture

simTD is the worldwide first field operational trial for car-to-x (C2X) technology that applies several hundred vehicles and roadside stations in a real-life environment in order to evaluate the entire spectrum of applications with regard to effects on traffic safety and traffic efficiency.

For a comprehensive integration of security into the simTD architecture several challenges have to be met. It has to be examined which security standards can be deployed with the given architecture. Adaptations and further extensions of common standards are necessary in order to fit the security and privacy mechanisms into the entire C2X architecture. Furthermore the security mechanisms have to deal with hardware restrictions due to the high availability requirements and the restrictions in terms of costs and resources that are typical for automotive environments. Finally novel concepts have to be developed with regard to the scale factor of the large fleet consisting of vehicles and infrastructure.

In this presentation we give a first glance on a near-series security architecture for C2X communications. We present the different concepts, protocols and cryptographic procedures used in simTD. Furthermore strategies to protect the driver's privacy based on pseudonyms are proposed.

CAST Online Workshops

In these times of COVID-19 restrictions in particular, questions of cyber security remain highly topical. CAST would like to make its contribution and will be organising the CAST workshops online as virtual events from July 2020. This will ensure a continuous exchange of knowledge on current cyber security issues.

The CAST workshops in digital format will be implemented with the open source web conference system BigBlueButton, which is operated with a CAST-owned server located in Darmstadt to ensure data protection.

As soon as the COVID-19 restrictions allow it, CAST will return to the usual workshop format and is already looking forward to welcoming you again personally in Darmstadt.
