) -> (Self::CommitParameters, Self::CommitmentRandom)where
Self: Sized,
fn commitment( params: &Self::GroupParameters, x: &Self::Secret ) -> (Self::CommitParameters, Self::CommitmentRandom)where Self: Sized,
Generates a commitment to a secret on the Pallas curve.
Parameters
params- Group parameters of the Pallas curve.x- The secret scalar value to which the commitment is made.
Returns
Returns a tuple containing the commitment parameters and a commitment random scalar.
source§fn challenge(_: &GroupParams<Point>) -> Self::Challenge
fn challenge(_: &GroupParams<Point>) -> Self::Challenge
Generates a random challenge scalar.
Parameters
_params- Ignored in this implementation. Group parameters can be used if needed.
Returns
Returns a random scalar value to be used as a challenge.

_: &Self::GroupParameters,
k: &Self::CommitmentRandom,

) -> Self::Responsewhere
Self: Sized,
fn challenge_response( _: &Self::GroupParameters, k: &Self::CommitmentRandom, c: &Self::Challenge, x: &Self::Secret ) -> Self::Responsewhere Self: Sized,
Generates a response to a challenge given a secret and a random scalar.
Parameters
_params- Ignored in this implementation. Group parameters can be used if needed.k- The random scalar used during commitment.c- The challenge scalar.x- The secret scalar.
Returns
Returns the response scalar, which is calculated as k + (c * x).
source§fn verify(
params: &Self::GroupParameters,
s: &Self::Response,
c: &Self::Challenge,
cp: &Self::CommitParameters
) -> bool
fn verify( params: &Self::GroupParameters, s: &Self::Response, c: &Self::Challenge, cp: &Self::CommitParameters ) -> bool
Verifies the correctness of the response to a challenge.
Parameters
params- Group parameters of the Pallas curve.s- The response scalar.c- The challenge scalar.cp- The commitment parameters tuple.
Returns
Returns true if the verification is successful, false otherwise.
