pub struct CiphertextCommitmentEqualityProof { /* private fields */ }Expand description
Equality proof.
Contains all the elliptic curve and scalar components that make up the sigma protocol.

impl CiphertextCommitmentEqualityProof
Sourcepub fn new(
keypair: &ElGamalKeypair,
ciphertext: &ElGamalCiphertext,
opening: &PedersenOpening,
amount: FieldValue<ScalarField>,
transcript: &mut Transcript<BooleanValue>,
) -> Self
pub fn new( keypair: &ElGamalKeypair, ciphertext: &ElGamalCiphertext, opening: &PedersenOpening, amount: FieldValue<ScalarField>, transcript: &mut Transcript<BooleanValue>, ) -> Self
Creates a ciphertext-commitment equality proof.
The function does not hash the public key, ciphertext, or commitment into the transcript. For security, the caller (the main protocol) should hash these public components prior to invoking this constructor.
This function is randomized. It uses random singlets internally to generate random scalars.
Note that the proof constructor does not take the actual Pedersen commitment as input; it takes the associated Pedersen opening instead.
keypair- The ElGamal keypair associated with the first to be provedciphertext- The main ElGamal ciphertext to be provedopening- The opening associated with the main Pedersen commitment to be provedamount- The message associated with the ElGamal ciphertext and Pedersen commitmenttranscript- The transcript that does the bookkeeping for the Fiat-Shamir heuristic
