Safety & Security in the Context of Autonomous Driving With the advent of cypherphysical (systems of) systems, new challenges for safety and security arise. Especially in the context of autonomous driving we are currently facing a complex environment, where security problems can easily result in safetyrelevant issues, and vice versa. There have been multiple approaches in the past to combine the approaches from safety and security best practices into a combined view, all with their individual challenges. We propose a fully integrated approach, combining safety with security and modelling their complex interactions. In this work we start by giving a thorough definition of the basic terms and concepts used in safety and security, in order to identify similarities and differences. We then propose and outline a combined view on the safety and security causal chains and define their interdependencies.

Preliminary Considerations for a Cooperative Intelligent Transport System Cybersecurity Reference Architecture Cyber security and privacy are major challenges for interconnected automatic driving cars which rely on confidentiality, integrity, availability, authenticity, accountability as well as privacy of a cooperative intelligent transport system (CITS). The cars require detailed data about the environment on different levels to generate a comprehensive overview of the current traffic situation in real time to ensure their safe and secure movement. The availability, integrity, authenticity and accountability of data and its processing are a prerequisite for automated and interconnected driving. Additionally, confidentiality and privacy are main requirements for using CITS services. Cyber security is not only necessary for an efficient traffic management. Cooperative functions and coordinative autonomy is mandatory, since successful intentional attacks on a CITS in fact threaten human lives. There is a fundamental need for a comprehensive harmonization of safety and security aspects from the infrastructure provideru0027s perspective to ensure awareness and trust  and not solely from an original equipment manufactureru0027s (OEM) view. Especially cyber security is essential to make these cooperative traffic structures and autonomous interconnected driving technologies confidently available to society. In this paper, the approach for component identification, scoping, use case development, and the applied risk management method as preliminary work for the development of a comprehensive CITS cybersecurity reference framework is discussed. These steps are part of a currently ongoing research project.
