FLOURISH Secure, Trustworthy and Robust Communications Findings

11 November 2019

As vehicles become increasingly connected, it is essential that communications are cyber-resilient and secure. This is vital for gaining public trust in connected and autonomous vehicle (CAV) technology and delivering the transformative benefits expected of CAVs. FLOURISH therefore focused on developing state-of-the-art technologies and methodologies to enable the safe and secure communications required for CAVs.

FLOURISH explored how to ensure a safe and robust mechanism for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. The pioneering application of fog-based computing to CAVs by the University of Bristol allows the agile provision of trust for CAVs. It allows unsafe vehicles in the network to be identified quickly, meaning that other users can avoid them and know not to trust the information they are sharing. Furthermore fog-based computing reduces the transmission times between vehicles and infrastructure, improving safety.

Fog-based computing can enable unsafe vehicles to be identified quickly.


In relation to detecting anomalies in the transport system, Airbus – in partnership with De Montfort University – developed an Artificial Intelligence (AI) based Intrusion Detection System utilising machine learning. This system would be able to detect different types of cyber-attack against V2V communications – reducing the risk of traffic disruptions caused by cyber-attacks. The key focus for this activity was the detection of spoofing and jamming attacks on vehicle platoons. Airbus also explored the application of model-based systems engineering (MBSE) to CAVs. MBSE is becoming more recognised as good practise for managing the complexity in systems engineering. For humans, graphical models offer a much more approachable introduction in to how a system will be or is built over a traditional document centric approach.

During FLOURISH, Atkins also developed an innovative Incident Response Framework that provides guidance to help ensure future CAV system resilience. This framework allows incidents that could undermine the integrity or the performance of both the vehicle and network to be identified and assessed for the level of threat and impact they pose. The incident scenarios vary in their make-up and consider topics including safety, cyber security, deliberate interference and accidental failures . Alongside this guidance, the Incident Response Framework presents several key recommendations that will be required for the cyber-secure deployment of CAVs in the UK. The Incident Response Framework is a crucial basis for the development of a roadmap for the cyber-secure integration of CAVs in our transport system; a pre-requisite to any mass-scale deployment of CAVs in the UK.

As vehicles continue to become more connected, the findings from FLOURISH can be used to ensure that technology is deployed in the most secure, trustworthy and robust way – allowing users, transport authorities and cities to trust the technology and fully experience the benefits it can unlock.
