Struct xaynet_core::message::Update

pub struct Update {
    pub sum_signature: ParticipantTaskSignature,
    pub update_signature: ParticipantTaskSignature,
    pub masked_model: MaskObject,
    pub masked_scalar: MaskObject,
    pub local_seed_dict: LocalSeedDict,
}

A high level representation of an update message.

These messages are sent by update participants during the update phase.

Fields

sum_signature: ParticipantTaskSignature

The signature of the round seed and the word "sum".

This is used to determine whether a participant is selected for the sum task.

update_signature: ParticipantTaskSignature

Signature of the round seed and the word "update".

This is used to determine whether a participant is selected for the update task.

masked_model: MaskObject

A model trained by an update participant.

The model is masked with randomness derived from the participant seed.

masked_scalar: MaskObject

The scalar used to scale model weights.

The scalar is masked with randomness derived from the participant seed.

local_seed_dict: LocalSeedDict

A dictionary that contains the seed used to mask masked_model.

The seed is encrypted with the ephemeral public key of each sum participant.

Trait Implementations
