As vehicles become more connected, the potential for cyber threats grows significantly and robust security measures are more relevant. The AutoCHERI project focuses on enhancing the cybersecurity of the fast-growing Connected and Autonomous Vehicles (CAVs) using the CHERI (Capability Hardware Enhanced RISC Instructions) architecture. This technology aims to refine the cybersecurity framework of CAVs, targeting memory safety and compartmentalisation to mitigate vulnerabilities. Anna Stylianou, part of Applus+ IDIADA, explains how our expertise in systems engineering, validation and regulatory analysis contributes to this project.
AutoCHERI is a hybrid capability architecture that addresses the increasing cybersecurity risks in the rapidly evolving CAV sector. It started in 2022 with funding and support from Innovate UK’s Digital Security by Design (DSbD), an initiative aimed to create a more resilient future through the transformation of digital technology. Our company is working to ensure that the implementation of CHERI architecture complies with industry standards and meets the latest cybersecurity requirements. Anna Stylianou, Cybersecurity Team Lead at Applus+ IDIADA, contributes to AutoCHERI by analysing project requirements and providing technical cybersecurity guidance. Her role involves evaluating use case system architectures and conducting comprehensive threat analyses and risk assessments, as well as performing technical vehicle testing.
This project is a collaborative effort among several key partners, each bringing unique expertise. The consortium includes Applus+ IDIADA, Beam Connectivity, Swansea University, University of Exeter and CSA Catapult. By maintaining a client-centric approach, AutoCHERI ensures that deliverables meet expectations while adapting to evolving requirements. Risk assessment and management, such as technical challenges and resource constraints, are integral to its success. Team members are empowered to propose and test innovative ideas, leveraging their diverse backgrounds and expertise.
The short-term objective is investigating the use of DSbD technology based on the CHERI architecture to secure vehicle telematics, the systems that retrieve the data generated by said vehicles. This involves comparing the performance and cyber resilience of a new Telematics Control Unit (TCU) with conventional processors and architectures. The long-term goal is to engage with key sector players and industry bodies to promote the widespread adoption of AutoCHERI technology, thereby advancing secure hardware solutions for Electronic Control Units, which serve as the main component of a vehicle's electronic system. Their purpose is to ensure safety and overall performance on one or more of the vehicle's systems.
AutoCHERI brings multiple benefits to Applus+, enhancing our capabilities in automotive cybersecurity. Collaborating with leading academic institutions and industry experts grants access to research and technology. Moreover, we significantly contribute to societal and innovation goals, enhancing the safety and privacy of connected and highly autonomous vehicles and promoting safer transportation overall.
