Explore the integration of Rust programming language within the OP-TEE (Open Portable Trusted Execution Environment) ecosystem in this 34-minute conference talk from the Linux Foundation. Discover how memory safety becomes critical in OP-TEE applications that provide secure interfaces for handling user credentials, system keys, and confidential data, especially when interfacing with potentially compromised rich operating systems. Learn about the evolution of Rust support in OP-TEE and the journey to establish Rust as a first-class citizen for developing Trusted Applications (TAs). Examine strategies for building Rust-based TAs that achieve performance parity with their C counterparts while leveraging Rust's memory-safety guarantees to harden the TEE environment against memory-based exploits. Gain insights into current development progress and explore future possibilities for incorporating Rust's memory-safety and thread-safety features directly into the OP-TEE core, including considerations for enabling pseudo trusted applications written in Rust.
