Struct DLEQProof 

pub struct DLEQProof {
    pub(crate) c: Scalar,
    pub(crate) s: Scalar,
}

A DLEQProof is a proof of the equivalence of the discrete logarithm between two pairs of points.

Fields

c: Scalar

c is a Scalar \(c=H_3(X,Y,P,Q,A,B)\)

s: Scalar

s is a Scalar \(s = (t - ck) \mod q\)
