Enclave

This is the monorepo for Enclave, an open-source protocol for Encrypted Execution Environments (E3).

Architecture

Enclave employs a modular architecture involving numerous actors and participants. The sequence diagram below offers a high-level overview of the protocol, but necessarily omits most detail.

    participant Users
    participant Enclave

    participant E3Program
    participant ComputeProvider
    participant InputValidator
    participant DecryptionVerifier

    Users->>Enclave: request(parameters)
    Enclave->>E3Program: validate(e3ProgramParams)
    E3Program-->>Enclave: inputValidator
    Enclave->>ComputeProvider: validate(computeProviderParams)
    ComputeProvider-->>Enclave: decryptionVerifier
    Enclave->>CiphernodeRegistry: requestCommittee(e3Id, filter, threshold)
    CiphernodeRegistry-->>Enclave: success
    Enclave-->>Users: e3Id, E3 struct

    Users->>Enclave: activate(e3Id)
    Enclave->>CiphernodeRegistry: committeePublicKey(e3Id)
    CiphernodeRegistry-->>Enclave: publicKey
    Enclave->>Enclave: Set expiration and committeePublicKey
    Enclave-->>Users: success

    Users->>Enclave: publishInput(e3Id, data)
    Enclave->>InputValidator: validate(msg.sender, data)
    InputValidator-->>Enclave: input, success
    Enclave->>Enclave: Store input
    Enclave-->>Users: success

    Users->>Enclave: publishCiphertextOutput(e3Id, data)
    Enclave->>DecryptionVerifier: verify(e3Id, data)
    DecryptionVerifier-->>Enclave: output, success
    Enclave->>Enclave: Store ciphertextOutput
    Enclave-->>Users: success

    Users->>Enclave: publishPlaintextOutput(e3Id, data)
    Enclave->>E3Program: verify(e3Id, data)
    E3Program-->>Enclave: output, success
    Enclave->>Enclave: Store plaintextOutput
    Enclave-->>Users: success
