Challenges of Delivering and Protecting Third-party Firmware Libraries on Microcontroller Systems
Today€™s microcontrollers designed for the IoT may come pre-loaded with a range of firmware from multiple vendors. While TrustZone for Armv8-M helps the protection of the device from hackers and untrusted parties, there are some cases where a fragmented supply chain can cause a higher risk of leaking trade secrets for firmware vendors. In these instances, devices need additional IP protection capabilities. These new capabilities bring changes to the processor's debug features, memory protection architecture and system-level security features. This presentation explains the background of these requirements, and how new features in the Armv8.1-M architecture can help chip vendors to deliver a solution to these challenges. For example, demonstrating how the Unprivileged Debug Extension (UDE) feature in Armv8.1-M restricts debug visibility to a specific software partition. To utilize UDE, debug tools and software require some adaptations and the devices need debug authentication support.
