Trait implemented by additively homomorphic cryptosystems

Required Methods

fn add(
    &self,
    ciphertext_a: &Self::Ciphertext,
    ciphertext_b: &Self::Ciphertext
) -> Self::Ciphertext

Combines two ciphertexts so that their decrypted value reflects some addition operation

fn sub(
    &self,
    ciphertext_a: &Self::Ciphertext,
    ciphertext_b: &Self::Ciphertext
) -> Self::Ciphertext

Combines two ciphertexts so that their decrypted value reflects some subtract operation

fn mul_constant(
    &self,
    ciphertext: &Self::Ciphertext,
    input: &Self::Input
) -> Self::Ciphertext

Applies some operation on a ciphertext so that the decrypted value reflects some multiplication with input

fn add_constant(
    &self,
    ciphertext: &Self::Ciphertext,
    constant: &Self::Plaintext
) -> Self::Ciphertext

Combines two ciphertexts so that their decrypted value reflects some addition operation with a constant

fn sub_constant(
    &self,
    ciphertext: &Self::Ciphertext,
    constant: &Self::Plaintext
) -> Self::Ciphertext

Combines two ciphertexts so that their decrypted value reflects some subtract operation with a constant
