A trait for engines encrypting (discarding) LWE ciphertext vectors.

Semantics

This discarding operation fills the output LWE ciphertext vector with the element-wise encryption of the input plaintext vector under the key LWE secret key.

Required Methods

fn discard_encrypt_lwe_ciphertext_vector(
    &mut self,
    key: &SecretKey,
    output: &mut CiphertextVector,
    input: &PlaintextVector,
    noise: Variance
) -> Result<(), LweCiphertextVectorDiscardingEncryptionError<Self::EngineError>>

Encrypts an LWE ciphertext vector.

    &mut self,
    key: &SecretKey,
    output: &mut CiphertextVector,
    input: &PlaintextVector,
    noise: Variance
)

Unsafely encryprs an LWE ciphertext vector.
