Securing Federated Learning

[ghost]

Would it be possible to do a complete example of cryptographic-based secure aggregation for federated learning? You provided some intro to secrete sharing, encryption, and decryption. But would it be possible to complete that example in "completed" called Section 3 - Securing Federated Learning?
Because the last part where it says "Final Project: Federated Learning with Encrypted Gradient Aggregation" is still missing.

Thank you in advance
