Developing a QRNG ECU for automotive security: Experience of testing in the real-world

Over the last decade, automotive components and systems have become increasingly connected and digital in nature. This trend has significantly increased the risk of malicious interference with car components, vehicles and infrastructure, and cybersecurity defences have generally proven to be lacking. The success of, and trust in, connected and autonomous vehicles (CAVs) relies upon these security gaps being closed as soon as possible. To this end, Crypta Labs introduced a novel electronic control unit (ECU) prototype for enabling secure digital communication in the transport domain. Due to its novelty, it is a challenge to evaluate its functionality, robust and reliable for automotive platforms. In this paper, we introduce the novel ECU, apply a testing methodology specially adapted to this product to achieve the evaluation goal, and conclude with a discussion.
