}

A trait for engines trivially encrypting LWE ciphertext vectors.

Semantics

This pure operation generates an LWE ciphertext vector containing the element-wise trivial encryption of the input plaintext vector, with the requested lwe_size.

Formal Definition

A trivial encryption uses a zero mask and no noise. It is absolutely not secure, as the body contains a direct copy of the plaintext.

Required methods

fn trivially_encrypt_lwe_ciphertext_vector(
    &mut self,
    lwe_size: LweSize,
    input: &PlaintextVector
) -> Result<CiphertextVector, LweCiphertextVectorTrivialEncryptionError<Self::EngineError>>

Trivially encrypts an LWE ciphertext vector.

unsafe fn trivially_encrypt_lwe_ciphertext_vector_unchecked(
    &mut self,
    lwe_size: LweSize,
    input: &PlaintextVector
) -> CiphertextVector

Unsafely creates the trivial LWE encryption of the plaintext vector.
