My First Function

This documentation will guide you through executing your first function on the Teaclave platform.

Prerequisites

To run Teacalve, a hardware with Intel SGX support is needed. You can check with this list of supported hardware. Note that you need to configure BIOS to enable SGX sometime. Additionally, you need to install driver and platform software to run SGX applications. Details can found in Intel SGX Installation Guide.

If you don't have an SGX supported hardware at hand, Teaclave can also run in simulation mode. However some functions like remote attestation will be disable at this mode.

Clone and Build Teaclave

Clone the Teaclave repository:

$ git clone https://github.com/apache/incubator-teaclave.git

Since the building dependencies is a bit complicated, we suggest to build the Teaclave platform with our docker images. You can learn more details about the building environment from Dockerfile under the docker directory.

Build the Teaclave platform using docker:

$ cd incubator-teaclave
$ docker run --rm -v $(pwd):/teaclave -w /teaclave \
  -it teaclave/teaclave-build-ubuntu-1804-sgx-2.9:latest \
   bash -c ". /root/.cargo/env && \
     mkdir -p build && cd build && \
     cmake -DTEST_MODE=ON .. && \
     make"

To build in simulation mode, you can add -DSGX_SIM_MODE=ON to cmake.

Setup Attestation Service

For simplicity, we use Intel Attestation Service (IAS) in this tutorial. To get started, you need to enroll in Intel SGX Attestation Service in Intel's attestation service portal by subscribing the attestation service for development (linkable is preferred). Then, you can find “SPID” and “Primary key” in the subscription details for later usage.

There is one more setup if you are using linkable attestation service subscription. Edit the /etc/aesmd.conf file and uncomment the default quoting type = epid_linkable line to enable linkable quotes for EPID-based attestation service (i.e., Intel Attestation Service). At last, the AESM service need to be restarted by sudo systemctl restart aesmd.

Launch Teaclave Services

Teaclave contains multiple services. To ease the deployment, you can use docker-compose to manage all services in a containerized environment.

Setup environment variables:

$ export AS_SPID="00000000000000000000000000000000"  # SPID from IAS subscription
$ export AS_KEY="00000000000000000000000000000000"   # Primary key/Secondary key from IAS subscription
$ export AS_ALGO="sgx_epid"                          # Attestation algorithm, sgx_epid for IAS
$ export AS_URL="https://api.trustedservices.intel.com:443"    # IAS URL

Launch all services with docker-compose:

$ (cd docker && docker-compose -f docker-compose-ubuntu-1804.yml up --build)
