EGo multi-party computing module

This module provides the base functionality for building confidential multi-party computing (MPC) apps in Intel SGX enclaves with EGo. MPC here refers to multiple users wanting to selectively share information through a shared host without revealing raw data. More specifically, the module provides a server with a relational database handling trusted ownership, encryption, authentication, and secure connections with the client through attested TLS (aTLS).

Architecture

An MPC server is implemented using the following packages:

• server: The server serves a user-defined HTTP REST API and handles attestation.
• db: The db package provides an encrypted SQLite database exposed via GORM.
• seal: The seal package provides helper functions for sealing the database encryption key.

The client is implemented using the client package. The idea is to run the client as a local proxy server that handles all the confidential-computing-related complexities, such as attestation and secure connections. This allows to create user interfaces that can use standard HTTP connections to the local proxy.
