Apples and Cars: a Comparison of Security
This work addresses cybersecurity risks for increasingly software-dependent cars, offering insights for automotive engineers and security researchers, though it is incremental as it applies existing smartphone security concepts to a new domain.
The paper compared the security architectures of iPhones and cars to identify gaps, finding that automotive systems share similarities with smartphones but lack equivalent protection layers, highlighting potential improvements for future vehicle security.
Cybersecurity has gained importance for cars that increasingly rely on software and networks. "Smartphone on wheels" is often used as an analogy to highlight the need for security. As a high-value target of cyberattacks, modern smartphones implement layers of protection. Automotive embedded systems share many similarities with smartphones. We compare the security architecture of an iPhone and a car to identify gaps and discuss the potentials for the cars of the future.
