ZeroCiphertextProof

arcis_compiler::utils::zkp::zero_ciphertext

Struct ZeroCiphertextProof 

Source 
pub struct ZeroCiphertextProof { /* private fields */ }
Expand description

Zero-ciphertext proof.

Contains all the elliptic curve and scalar components that make up the sigma protocol.

Implementations§

Source§

impl ZeroCiphertextProof

Source

pub fn new( elgamal_keypair: &ElGamalKeypair, ciphertext: &ElGamalCiphertext, transcript: &mut Transcript<BooleanValue>, ) -> Self

Creates a zero-ciphertext proof.

The function does not hash the public key and ciphertext 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.

  • elgamal_keypair - The ElGamal keypair associated with the ciphertext to be proved
  • ciphertext - The main ElGamal ciphertext to be proved
  • transcript - The transcript that does the bookkeeping for the Fiat-Shamir heuristic
