HE-based secure aggregation protocols are more suitable for Cross-Silo federation learning than the other two secure aggregation protocols for two reasons: The first reason is Because Cross-Silo federation learning has fewer clients, it is vulnerable to inference attacks on structural models. Whereas, in a secure aggregation protocol based on HE, the model is private. The second reason is HE has a high overhead, while the clients in Cross-Silo federation learning have stable communication and abundant computational resources and can afford the overhead of HE to some extent. Some secure aggregation protocols based on HE are described below.
