Automotive cyber security assurance framework

5StarS addresses the increased threat from cyber attacks with the proliferation of connected and autonomous road vehicles.


The consortium, which partners Ricardo with HORIBA MIRA, Roke, Thatcham Research and Axillium Research, will develop a 5-star type consumer rating framework, analogous to existing Euro NCAP vehicle safety ratings. This will provide consumers with a transparent and clear grading of a vehicle’s cyber security enabling manufacturers to maximise return on their investment in cyber-secure systems.

Customer Benefit

Cyber security is critical to ensuring consumer trust - a significant barrier to adoption of CAVs (connected autonomous vehicles). The automotive industry currently lacks standards throughout the vehicle supply chain upon which consumers can build this trust.

The consumer rating framework provided by 5StarS will independently assess the cyber security of new vehicles, clarifying risk for the insurance industry, and enabling OEMs, consumers, and the supply chain to have confidence and trust in critical CAV technology.

The standard will also support improved design in the industry by identifying gaps in the cyber engineering of a product. By providing a clear standard to achieve beforehand, the development of new technology and products accelerates as the 5StarS framework provides common targets against which competing manufactures can innovate to produce the optimum solution to exceed the threshold of a 5-Star rating.


The project will develop an assurance methodology for CAV products that ensures that resulting CAV technologies achieve cyber security robustness and resilience whilst achieving trust by manufacturers and consumers.

Ricardo’s responsibility is to identify test methodology through which cyber security standards can be consistently assessed, thus providing consumers with a consistent rating of a vehicle’s resilience against potential cyber security threats.
