Introduction

Pollux provides tools for orchestrating various secure multi-party computation (MPC) systems. MPC is a general paradigm that enables accurate analytics on private data from multiple sources and derives its security through mathematical cryptography. It differs from, but can be combined with, other privacy approaches such as trusted hardware or differential privacy. An example of an MPC system is Divvi Up, which is a privacy-respecting telemetry service developed by the Internet Security Research Group (ISRG).

In general, the tools provided by Pollux consist of Docker Compose files, Terraform files, and helper shell scripts. The Docker Compose files provide the fundamental ability to deploy the MPC system's components on any Docker-enabled machine, the Terraform files allow the deployments to be hosted on cloud machines, and the helper shell scripts make it easier to configure certain parts of the deployment.
