A trait for engines encrypting GGSW ciphertexts containing a single plaintext.

Semantics

This pure operation generates a GGSW ciphertext containing the encryption of the input plaintext, under the key secret key.

Formal Definition

Required Methods

fn encrypt_scalar_ggsw_ciphertext(
    &mut self,
    key: &SecretKey,
    input: &Plaintext,
    noise: Variance,
    decomposition_level_count: DecompositionLevelCount,
    decomposition_base_log: DecompositionBaseLog
) -> Result<Ciphertext, GgswCiphertextScalarEncryptionError<Self::EngineError>>

Encrypts a plaintext into a GGSW ciphertext.

unsafe fn encrypt_scalar_ggsw_ciphertext_unchecked(
    &mut self,
    key: &SecretKey,
    input: &Plaintext,
    noise: Variance,
    decomposition_level_count: DecompositionLevelCount,
    decomposition_base_log: DecompositionBaseLog
) -> Ciphertext

Unsafely encrypts a plaintext vector into a GGSW ciphertext.
