}

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.

Formal Definition

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.
