Explore the concept of physical partitioning for enhanced security in this 48-minute conference talk from linux.conf.au. Learn about the Betrusted project, which aims to create a separate device for secure applications using security-first principles. Discover how this approach minimizes attack surfaces, eliminates microarchitectural side channels, and allows users to focus on secure transactions. Gain insights into the project's scope, from secure silicon to application layer code, and find out how to contribute to this open-source initiative. Delve into topics such as secure enclaves, hardware verification, the Xous operating system, and the challenges of creating trustworthy hardware and software.
