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 system
• BUILD_STD=no: Traditional no_std cargo build for minimal footprint
• BUILD_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.
