# Third-Party Dependency Vendoring

For Teaclave, since all SGX/enclave dependencies are part of trusted computing base (TCB), in order to ease auditing, ensure product stability, as well as reduce the possibility of the supply chain attack, we vendored all TEE dependencies here. During the build process, both the untrusted (i.e., the app part) and trusted components (i.e., the enclave part) will only consume packages from this designated repository and will not download any code from external package registry such as crates.io.

Basically, we have these submodules:

  • crates-io: Rust crates vendored from crates.io for non-SGX components.
  • crates-sgx: Vendored crates ported for SGX (i.e., using Teaclave SGX SDK).
  • mesapy: a Python interpreter targeting SGX.
  • rust-sgx-sdk: Teaclave SGX SDK for standard libraries and Rust bindings of SGX libraries.
  • webassembly-micro-runtime: A sandboxed runtime to execute(interpret) WebAssembly bytecode.
