rust sgx sdk helloworld example

[sbellem]

The goal of this example is to show how one can use docker image with nix to reproduce an enclave build (enclave.so file) and moreover how an auditor, using their own private key, could verify the signed enclave (enclave.signed.so).

• Complete the documentation under README.md (https://github.com/initc3/nix-sgx-sdk/tree/rust-sgx-sdk#rust-sgx-sdk).
• Figure out why nix-build ... does not work, whereas building in the nix-shell session works.
• Package the rust sgx sdk separately such that it can be re-used for other applications (other than the samples that are under the rust sgx sdk codebase).
• Simplify auditor example, such that one mainly needs to input the signed enclave file and the source code.

The work is under the branch https://github.com/initc3/nix-sgx-sdk/tree/rust-sgx-sdk.

More involved examples, with remote attestation:

• Mutual Remote Attestation code sample
• Untrusted-Enclave Remote Attestation code sample

Both examples are based on the paper Integrating Remote Attestation with Transport Layer Security.

• Also, see the secret provisioning example at https://github.com/cloud-security-research/sgx-ra-tls/tree/master/apps/secret-provisioning-example.
