Apache Teaclave (incubating) SGX SDK helps developers to write Intel SGX applications in the Rust programming language, and also known as Rust SGX SDK.
The SDK container can either be built from source or pulled from docker hub and run as a docker container.
The docker image now supports Intel ME. If you need it, please refer to the sgxtime readme for instructions.
You can find the installation guides for Intel SGX software on the 01.org website.
Note: if you are running our SDK on a machine without SGX support, you will still need the simulation versions of the Intel PSW and SDK.
It is assumed that the user has correctly installed docker. We provide 5 containers:
baiduxlab/sgx-rust:1604-1.1.3baiduxlab/sgx-rust:1804-1.1.3baiduxlab/sgx-rust:2004-1.1.3baiduxlab/sgx-rust:fedora31-1.1.3baiduxlab/sgx-rust:centos8-1.1.3
With latest pinned to 1604-1.1.3.
First, pull the docker container of your choosing, this command will download latest:
$ docker pull baiduxlab/sgx-rust
To run the container, we recommend that you download our samplecode
We recommend starting by using the github repository as a first volume to run the container on:
$ git clone https://github.com/apache/incubator-teaclave-sgx-sdk.git
To run the container with SGX support, run:
$ docker run -v /path/to/rust-sgx:/root/sgx --device /dev/libsgx -ti baiduxlab/sgx-rust
If instead, you are using DCAP drivers you must run:
$ docker run -v /path/to/rust-sgx:/root/sgx -ti --device /dev/sgx/enclave --device /dev/sgx/provision baiduxlab/sgx-rust
Whilst inside the container, we must start the AESM daemon and define LD_LIBRARY_PATH:
# LD_LIBRARY_PATH=/opt/intel/sgx-aesm-service/aesm/
# /opt/intel/sgx-aesm-service/aesm/aesm_service
If everything has been properly configured, it is now possible to run a quick helloworld program inside the container:
# cd sgx/samplecode/helloworld
# make
# cd bin
# ./app
We recommend you look at other files in the samplecode folder to familiarize yourself with programming in our SDK.
Note: Intel provides a simulation mode so you can develop on regular machines, by building the enclave app using the libraries sgx_urts_sim, lsgx_uae_service_sim, sgx_trts_sim, sgx_tservice_sim.
We recommend starting by using the github repository as a first volume to run the container on:
$ git clone https://github.com/apache/incubator-teaclave-sgx-sdk.git
To run the container without SGX support, run:
$ docker run -v /path/to/rust-sgx:/root/sgx -ti baiduxlab/sgx-rust
Once inside the container, when running any of the samplecode you may either:
- Modify the Makefile and set
SGX_MODEtoSW - Run
export SGX_MODE=SW - Run
makewith the build flagSGX_MODE=SW
We may now run our helloworld example:
# cd sgx/samplecode/helloworld
# make SGX_MODE=SW
# cd bin
# ./app
Make sure Intel SGX SDK is properly installed and service started on the host OS. Then cd dockerfile and run docker build -t rust-sgx-docker -f Dockerfile.1604.nightly . to build.
We provide eighteen code samples to help developers understand how to write Enclave code in Rust. These samples are located in the samplecode directory.
See Code Samples
-
helloworldis a very simple app. It shows some basic usages of argument passing, Rust string and ECALL/OCALLs. -
cryptoshows the usage of crypto APIs provided by Intel SGX libraries. It does some crypto calculations inside the enclave, which is recommended in most circumstances. -
localattestationis a sample ported from the original Intel SGX SDK. It shows how to do local attestation in Rust programming language. -
sealeddatasample shows how to seal secret data in an enclave and how to verify the sealed data. -
threadsample is a sample ported from the original Intel SGX SDK, showing some basic usages of threading APIs. -

ue-raprovides remote attestation based TLS connection between an untrusted party and one SGX enclave. See the readme for details. -
sgx-covshows how to use lcov with Rust SGX enclave to generate code coverage report. See the readme for details. -
tcmallocshows how to link Rust-SGX enclave with tcmalloc (provided by Intel SGX SDK), and test its performance with different kinds of workload.
See tips
- For fixed-length array in ECALL/OCALL definition, declare it as an array. For dynamic-length array, use the keyword
size=to let the Intel SGX knows how many bytes should be copied.
- Add
#[no_mangle]for every ECALL function.
-
For dynamic-length array, the only way is to use raw pointers in Rust. There are several functions to get/set data using raw pointers such as
offsetmethod. One can also useslice::from_raw_partsto convert the array to a slice. -
For Fixed-length array, the above method is acceptable. And according to discussions in issue 30382 and issue 31227, thin-pointers (such as fixed-length array) are FFI-safe for now, but undocumented. In the sample codes, we use fixed-length arrays for passing and returning some fixed-length data.
Supports Intel SGX SDK v2.12, and Rust nightly-2020-10-25. Added support to Ubuntu 20.04. We strongly recommend users to upgrade to Intel SGX SDK v2.12 and drivers to DCAP 1.36.2 and OOT 2.11.0. release_notes.
Version 1.1.2
Supports Intel SGX SDK v2.9.1, and Rust nightly-2020-04-07. v1.1.2 provides a handy crate sgx_signal, which enables signal capture. One can easily find the place where exception happens and finally triggered ud2. And we added Backtrace::capture in sgx_tstd. With the help of Intel SGX SDk v2.9.1's patch, dtor of thread local storage finally works on regular SGX thread and pthread thread. Removed sgx_core_futures since Rust is supporting async/await in no_std environment. Please refer to release_notes for more details.
Version 1.1.1
Supports Intel SGX SDK v2.9, and Rust nightly-2020-03-12. v1.1.1 contains a bunch of bug fix and new proc macro sgx_align to help with aligning given structure. For LVI migigation, it only works on C/C++ parts (EDL headers/Intel's libs) and supports both two modes: MITIGATION-CVE-2020-0551=LOAD or MITIGATION-CVE-2020-0551=CF. To enable it, one need env "MITIGATION-CVE-2020-0551=LOAD" to set this environment variable. For detailed information, please refer to release_notes for more details.
Version 1.1.0
Supports Intel SGX SDK v2.7.1, and Rust nightly-2019-11-25. v1.1.0 brings up dynamic static supports by thread::spawn, and almost everything of std::sync. Also v1.1.0 benefits from Intel SGX SDK's aligned memory allocation primitives to mitigate INTEL-SA-00219. Besides, we enabled is_x86_feature_detected! by parsing a hidden global CPU feature indicator initialized by Intel SGX urts/trts. And we provided Dockerfile for Fedora 27. For detailed information, please refer to release_notes for more details.
Version 1.0.9
Supports Intel SGX SDK v2.6, and Rust nightly-2019-08-01. Bumps everything to edition. Removed third_party directory since we have all of those dependencies forked and maintained with merge bot. Since Intel SGX SDK v2.6 imports some breaking changes in global thread metata, thread local features of v1.0.9 is not works on Intel SGX SDK v2.5. EDL and common headers are changed respectively. For detailed information, please refer to release_notes for more details.
Version 1.0.8
Supports the most recent Rust nightly (nightly-2019-05-22) and Rust stable (stable-2019-05-14). Code coverage support has been added to sgx_cov. Bug fixes in memory allocator and panicking routines. New third party libraries to support kvdb-memorydb. Please refer to release_notes for more details.
Version 1.0.7
Supports Intel SGX SDK v2.5. Master branch supports Rust nightly build (nightly-2019-04-26) and stable branch supports Rust stable build (stable-2019-04-25). Refactored sgx_tstd to support mio. More sample codes added, including Java/Go clients for ue-ra (Thanks to @bradyjoestar)!. And we are maintaining forks of popular crates on Github organization mesalock-linux. The ported crates are syncing with the original crates with the help of Pull bot and we manually port almost all tests from the original crates to test if the ported crate works well in SGX. Please refer to release_notes for further details.
We changed the built-in EDL files. Please carefully upgrade your EDL files on import statements. If you encountered any problems during compilation, please create issue and let me know. Thanks!
ATTENTION: (Ubuntu Channel) Starts from Intel SGX SDK 2.8, aesmd requires a environment variable to start. If you are using docker, please start aesmd as:
LD_LIBRARY_PATH=/opt/intel/sgx-aesm-service/aesm /opt/intel/sgx-aesm-service/aesm/aesm_service
Starts from Intel SGX SDK 2.5, aesmd requires a environment variable to start. If you are using docker, please start aesmd as:
LD_LIBRARY_PATH=/opt/intel/libsgx-enclave-common/aesm /opt/intel/libsgx-enclave-common/aesm/aesm_service
(CentOS Channel) As of 2.6, CentOS branch of Intel SGX SDK is still in format of bin executable. Please start the aesmd as past:
LD_LIBRARY_PATH=/opt/intel/sgxpsw/aesm /opt/intel/sgxpsw/aesm/aesm_service
Version 1.0.6
Fix bugs in sgx_alloc, sgx_types, ucd-generate and improve sgx_tunittest. Added rust-base58. Thanks to @elichai, @cbeck88, @brenzi and @nhynes.
Version 1.0.5
This version supports Rust nightly build (nightly-2019-01-28, v1.34.0) in the master branch and the most recent stable build (stable-2019-01-16, v1.32.0) in the rust-stable branch. It supports the latest Intel SGX SDK v2.4.0 and Ubuntu Linux 16.04+18.04. We provide support to Intel's Protected Code Loader. We provide sgx_ucrypto and sgx_crypto_helper for using SGX-style crypto primitives in untrusted app and RSA keypair serialization/deserialization in both trusted and untrusted programs. We re-organize ocall related interfaces and provide them in a new crate sgx_libc with a bunch of new ocall functions. In addition, we port net2 to SGX. Please refer to release_notes for further details.
Version 1.0.4
This version supports Rust nightly build (nightly-2018-10-01) in the master branch and the most recent stable build (stable-2018-09-25) in the rust-stable branch. It supports the latest Intel SGX SDK v2.3.1 and Ubuntu Linux 18.04. It now contains further third party libraries including: bit-vec, chrono, erased-serde, fxhash, nan-preserving-float, num-bigint, quick-error, raft-rs, time, webpki-roots, and yasna. Some third party libraries, like untrusted, parity-wasm and lazy-static, are removed because they support no_std and can be used directly from crates.io. We strongly recommend developers upgrade to v1.0.4 and use the most recent Rust release to build it due to the Security advisory for the standard library. Please refer to release_notes for further details.
Version 1.0.1
This version supports the Rust nightly build (nightly-2018-07-16) in master branch and the most recent Rust stable build (stable-2018-07-10). And it supports the latest Intel SGX SDK v2.2. New third party libraries include: bytes, http, iovec, rust-crypto, rust-fnv and rust-threshold-secret-sharing. New code sample 'secretsharing' and 'rust-threshold-secret-sharing' is provided by @davidp94. Please refer to release_notes for further details.
Version 1.0.0
We proudly announce v1.0.0 of rust-sgx-sdk! We port Parity's Webassembly Interpreter to Intel SGX and provide a full functional in-enclave wasmi sample, and a sample solution of two-party private-set-intersection resisting side-channel attacks! From this version, we start to support most recent stable branch of Rust instead of nightly for better stability and future production use. Thus, the stable branch of v1.0.0 supports the most recent Rust stable toolchain (1.26.0 stable-2018-05-07), while the master only supports Rust nightly toolchain of nightly-2018-04-11. Please refer to release_notes for further details.
Version 0.9.8
This version provides security updates regards to recent Spectre attacks in Intel SGX, and supports Rust stable (2018-03-01) (in branch named 'rust-stable'). It contains support of Intel SGX SDK 2.1.2 and a series of API functions to stop speculative execution on demand. In addition, we provide a ported version of rust-protobuf v1.4.4. Please refer to release_notes for further details.
Version 0.9.7
This version provides a new namespace: sgx_tstd::untrusted, including sgx_tstd::untrusted::fs sgx_tstd::untrusted::time and sgx_tstd::untrusted::path, providing supports to operation to ocalls in a untrusted namespace. The untrusted namespace is always enabled no matter untrusted_* is set or not. We urge the developers to use the sgx_tstd::untrusted namespace to port their crates, instead of using the untrusted_ series of features. Also, we renamed the untrusted_net feature to net for feature name unification. Please refer to release_notes for further details.
