}

A trait for engines decrypting LWE ciphertext vectors.

Semantics

This pure operation generates a plaintext vector containing the element-wise decryption of the input LWE ciphertext vector under the key secret key.

Required Methods

fn decrypt_lwe_ciphertext_vector(
    &mut self,
    key: &SecretKey,
    input: &CiphertextVector
) -> Result<PlaintextVector, LweCiphertextVectorDecryptionError<Self::EngineError>>

Decrypts an LWE ciphertext vector.

unsafe fn decrypt_lwe_ciphertext_vector_unchecked(
    &mut self,
    key: &SecretKey,
    input: &CiphertextVector
) -> PlaintextVector

Unsafely decrypts an LWE ciphertext vector.
