Occlum SGX Remote Attestation integrated in TLS connection
The MRSIGNER of the example/signing_key.pem is hardcoded in the enclave code:
6871A831CED408CD99F0ED31587CC2B5C728C99D4A0A1ADF2F0C5574EBBB00DC
You can generate your own signing key. Just use the following command:
openssl genrsa -3 -out signing_key.pem 3072
To get the MRSIGNER of the key, compile this project and use the following command:
./mrsigner signing_key.pem
Running Examples
Before running make sure you have installed the Occlum and the SGX driver.
You should also have the Occlum Rust toolchain installed to get occlum-cargo.
To test the project just run client and server scripts in different terminals:
./build_server.sh
./build_client.sh
Mutual RATLS examples
Examples show how to use the mRATLS (Mutual Remote Attestation TLS) in different situations:
- The first example shows how to create mRATLS HTTPS server and client
- The second example shows how to create mRATLS GRPCs server and client
Both the server and the client must be running inside the enclave. So during the remote attestation peers, acquire their RA certificates. And during the TLS handshake, they verify each other's RA certificates. The config allows to whitelist MRENCLAVE, MRSIGNER, PRODID, SVN of the peer.
RATLS examples
Example shows how to create RATLS HTTPS server and client. The server must be running inside the enclave. The client can be running anywhere. The server config allows to whitelist the public ec25519 key of the client. The client config allows to whitelist MRENCLAVE, MRSIGNER, PRODID, SVN of the server.
