Apache Teaclave™ SGX SDK
Apache Teaclave™ SGX SDK is a Rust SDK for developing Intel SGX applications. It enables developers to write secure, privacy-preserving applications using Intel Software Guard Extensions (SGX) technology with the safety and performance benefits of the Rust programming language.
Overview
Apache Teaclave™ SGX SDK provides a comprehensive development environment for building Intel SGX enclaves in Rust. The current version (v2.0) offers significant improvements over the legacy v1.1 , including:
- Modern Build System: Supports
cargo build with no_std, xargo build, and cargo-std-aware modes
- Rich Ecosystem: Direct support for Tokio and Tonic in enclave programming without modifications
- Lightweight Architecture: Refactored Intel’s SGX SDK using Rust, requiring only a minimal portion of Intel’s original SDK
- Robust Testing: Comprehensive testing framework with well-tested
sgx_tstd standard library
- Simplified Dependencies: Eliminates the need to maintain 100+ third-party dependencies; most Rust crates work without modifications
Build System
The SDK supports multiple build modes to accommodate different development preferences:
BUILD_STD=cargo (default): Uses the new std-aware cargo build systemBUILD_STD=no: Traditional no_std cargo build for minimal footprintBUILD_STD=xargo: Uses xargo build with customized sysroot
Sample Applications
The following sample applications demonstrate various SGX SDK capabilities:
- backtrace: Stack trace functionality in SGX enclaves
- cov: Code coverage analysis tools
- crypto: Cryptographic operations within enclaves
- helloworld: Basic SGX enclave example
- httpreq: HTTP client functionality
- hyper-rustls-https-server: HTTPS server using Hyper and Rustls
- logger: Logging capabilities for SGX applications
- regex: Regular expression processing
- rpc: Remote procedure calls using Tonic and Tokio
- seal: Data sealing and unsealing operations
- switchless: Switchless call optimization
- zlib-lazy-static-sample: Compression with lazy static initialization
Note: Migration of additional v1.1 samples to v2.0 is ongoing.
