Fed-BioMed v4.3 new release

Fed-BioMed v4.3 is now available.

It introduces Secure Aggregation functionality which further protects the federated learning process. Secure Aggregation encrypts model parameters sent by the nodes to the researcher. The researcher then computes aggregated model parameters but cannot access individual node's model parameters in cleartext.

Fed-BioMed Secure Aggregation uses Joye-Libert additively homomorphic encryption scheme (based on fault-tolerant-secure-agg implementation) and Shamir multi-party computation protocol (from MP-SPDZ software).

Bug fixes and misc updates are also included in the release.

More details about the new features can be found in the Fed-BioMed CHANGELOG.
