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.

    actor Requester
    actor Data Providers
    participant Enclave
    participant Ciphernode Registry
    participant Ciphernodes
    participant Computation Module
    participant Execution Module

    loop Each computation request
        Requester ->> Enclave: Request computation
        activate Enclave
            Enclave ->> Ciphernode Registry: Select Committee
            activate Ciphernode Registry
                Ciphernode Registry -->> Ciphernodes: Key Setup
                activate Ciphernodes
                    Ciphernodes -->> Ciphernode Registry: Publish shared keys
                deactivate Ciphernodes
                Ciphernode Registry -->> Enclave: Publish Committee
            deactivate Ciphernode Registry

            loop Each input
                Data Providers ->> Enclave: Publish inputs
                Enclave ->> Computation Module: Validate inputs
                activate Computation Module
                    Computation Module -->> Enclave: 👌
                deactivate Computation Module
            end

            Enclave ->> Execution Module: Request execution
            activate Execution Module
            Execution Module -->> Enclave: Publish ciphertext output
            deactivate Execution Module

            Enclave -->> Ciphernodes: Request plaintext output
            activate Ciphernodes
                Ciphernodes ->> Enclave: Publish plaintext output
            deactivate Ciphernodes

            Requester -->> Enclave: Get plaintext
            Enclave -->> Requester: Returns plaintext
        deactivate Enclave
    end
