Struct SecureAggregationConfig 

pub struct SecureAggregationConfig {
    pub num_clients: usize,
    pub gradient_dim: usize,
    pub round_seed: u64,
    pub quantization_scale: f64,
    pub modulus: i64,
    pub support_dropouts: bool,
}

Configuration for the Bonawitz-style secure aggregation protocol.

All clients in a round must agree on the same configuration so that the derived pairwise masks line up. The round_seed field acts as a public salt that lets the same fleet of clients run independent aggregation rounds (different round_seeds produce independent pairwise masks).

Fields

num_clients: usize

Total number of clients expected to participate in the round.

gradient_dim: usize

Dimensionality of the gradient vectors being aggregated.

round_seed: u64

Public, per-round salt mixed into every pairwise seed derivation.

quantization_scale: f64

Quantisation scale. Gradients are quantised by round(g * scale) before being lifted into the modular group; a larger scale gives finer fixed-point precision at the cost of needing a larger modulus to avoid wraparound.

modulus: i64

Modulus p of the additive group Z_p used for masking and aggregation. Must be substantially larger than quantization_scale * num_clients * max_gradient_magnitude to avoid information-destroying wraparound.

support_dropouts: bool

Whether to support dropout reconstruction at the server.
