Apache Teaclave? (incubating) TrustZone SDK

Apache Teaclave? (incubating) TrustZone SDK (Rust OP-TEE TrustZone SDK) provides abilities to build safe TrustZone applications in Rust. The SDK is based on the OP-TEE project which follows GlobalPlatform TEE specifications and provides ergonomic APIs. In addition, it enables the capability to write TrustZone applications with Rust's standard library (std) and many third-party libraries (i.e., crates).

Apache Teaclave? (incubating) TrustZone SDK provides two development modes for Rust TAs: no-std and std. We recommend using no-std by default. For a detailed comparison, please refer to Comparison.

UPDATES: We have developed a new build environment on the main branch, which will now be the only branch for development and maintenance and includes breaking changes to the legacy master branch. If you're using the master branch and wish to migrate to the new development branch (main), please refer to the migration guide.

?? Quick & Easy Start: Hello World TA in Emulator

Developing Trusted Applications (TAs) often requires specific hardware, which can be a barrier for many developers. To address this, we provide a prebuilt Docker environment that allows you to experience TAs without the need for physical hardware.

The Docker image automates the entire setup process for TrustZone emulation in QEMU, enabling you to focus on writing and testing your applications efficiently, without the hassle of manual configuration.

Choose your development mode in Emulator:

• ?? Quick Emulation And Development in Docker
• ?? Developing TAs with Rust Standard Library

Advanced Setup: Customize Your Build Environment

In addition to developing and testing Trusted Applications (TAs) in the QEMU emulator, setting up build configurations for specific hardware targets are also necessary. For detailed instructions on customizing your build environment, please refer to the Advanced Setup Documentation.

For other tips regarding the support Rust Examples, TA debugging, expanding secure memory, please refer to the docs/ directory.
