Description

This new feature will add homomorphic encryption to the existing federated parameter server.

The threat-model is based on honest-but-curious participants (coordinator and federated workers).

The homomorphic encryption protocol is xMK-CKKS which requires two communication rounds for the aggregation of weights. The protocol is described in https://arxiv.org/abs/2104.06824
