Struct PRP

pub struct PRP<F> { /* private fields */ }

Rescue pseudo-random permutation (PRP) instance

Implementations

impl<F: RescueParameter> PRP<F>

pub fn prp( &self, key: &RescueVector<F>, input: &RescueVector<F>, ) -> RescueVector<F>

Rescue pseudorandom permutation for Bls12381 scalars vectors of size 4 without key scheduled keys (scheduling occurs online)

pub fn prp_with_round_keys( &self, round_keys: &[RescueVector<F>], input: &RescueVector<F>, ) -> RescueVector<F>

Rescue pseudorandom permutation for Bls12381 scalars vectors of size 4 using scheduled keys

pub fn key_schedule(&self, key: &RescueVector<F>) -> Vec<RescueVector<F>>

Key scheduling for rescue based PRP for Bls12_381 scalars vector of size 4

pub fn mds_matrix_ref(&self) -> &RescueMatrix<F>

Return a pointer to the mds matrix. Does not expose secret states.

pub fn key_injection_vec_ref(&self) -> &[RescueVector<F>]

Return a pointer to the key injection vectors. Function needs to be public for circuits generation.. WARNING!!! May expose secret state if keys are supposed to be secret.

pub fn init_vec_ref(&self) -> &RescueVector<F>

Return a pointer to the initial vectors. Does not expose secret states.
