Practical Application of Verified Boot

Explore the practical application of verified boot procedures in embedded Linux systems through this 42-minute conference talk. Learn about the essential components required for cryptographically verifying bootloaders, kernels, and filesystems. Discover how to integrate these components using the OpenEmbedded build system. Gain insights into bootloader verification using the signing.bbclass in Yocto with the NXP CST tool, kernel verification through a fitimage class, and filesystem verification using a dm-verity class example. Understand common pitfalls encountered when deploying locked-down embedded systems and explore the implications of using GPLv3 licenses on such devices. Enhance your knowledge of secure boot processes and their implementation in embedded Linux environments.
