Enum sda_protocol::LinearMaskingScheme

pub enum LinearMaskingScheme {
    None,
    Full {
        modulus: i64,
    },
    ChaCha {
        modulus: i64,
        dimension: usize,
        seed_bitsize: usize,
    },
}

Supported masking schemes and their parameters.

Variants

None

No masking, i.e. secrets are shared direction to the clerks.

Full

Secure masking, using fresh randomness from the underlying operation system for each secret.

Fields of Full

modulus: i64

ChaCha

Secure masking, using a small random seed to derive masks (rand::chacha::ChaChaRng).

Compared to LinearMaskingScheme::Full this reduces the amount of mask data to be uploaded and downloaded by respectively participants and recipients. On the other hand, more computation has to be performed since seeds must be expanded on both participant and recipient side.

Fields of ChaCha

modulus: i64
dimension: usize
seed_bitsize: usize

Methods

impl LinearMaskingScheme

fn has_mask(&self) -> bool
