Thesis title: Automated identification of behavioural interactions between safety and security features in automotive systems
Abstract: Today’s transportation systems are undergoing a major transformation, driven by electrification, enhanced connectivity, and the integration of software-defined features and machine learning algorithms. These advancements substantially increase system complexity and the risk of unintended feature interactions. The shift towards automated driving reduces human involvement, heightening the need for systems that ensure both safety and security.
While standards such as ISO 26262 for functional safety and ISO/SAE 21434 for cybersecurity set stringent requirements, there is no industry standard that addresses the interactions between safety and security artefacts. Unintended interactions between these artefacts can introduce significant risks, including critical safety concerns. These challenges are compounded by differing terminologies, separate development teams, and tight delivery timelines, often resulting in late detection of these interactions, leading to higher costs and delays.
The primary goal of this thesis is to develop methodologies for identifying safety and security interactions in the automotive domain, thereby enhancing overall system dependability. The figure above highlights the safety and security interactions that we address in this thesis with numbered blue arrows.
We propose a method to identify the causal relationship between the behavioural specifications of correctly implemented security features and system component failures (indicated as number 1 in the figure). Additionally, we introduce methods to detect behavioural interactions between functional safety and cybersecurity features during the software architecture design phase (illustrated by number 2 in the figure). By developing tools to automate these methods, we enable the early identification of interactions in complex automotive systems, facilitating the utilisation of synergies and the resolution of conflicts, and thereby enhancing system dependability and performance.
