Fields

full_rounds: usize

Number of rounds in a full-round operation.

partial_rounds: usize

Number of rounds in a partial-round operation.

alpha: u64

Exponent used in S-boxes.

ark: &'static [[Fp<MontBackend<FrConfig, 4>, 4>; 3]]

Additive Round keys. These are added before each MDS matrix application to make it an affine shift. They are indexed by ark[round_num][state_element_index]

mds: &'static [[Fp<MontBackend<FrConfig, 4>, 4>; 3]]

Maximally Distance Separating (MDS) Matrix.

state: [Fp<MontBackend<FrConfig, 4>, 4>; 3]

Permutation state
