    Ciphertext: LweCiphertextEntity,
    Plaintext: PlaintextEntity,{
    fn trivially_decrypt_lwe_ciphertext(
        &mut self,

    ) -> Plaintext;
}

A trait for engines trivially decrypting LWE ciphertexts.

Semantics

This pure operation generates a plaintext containing the trivial decryption of the input ciphertext.

Formal Definition

Required Methods

fn trivially_decrypt_lwe_ciphertext(
    &mut self,
    input: &Ciphertext
) -> Result<Plaintext, LweCiphertextTrivialDecryptionError<Self::EngineError>>

Decrypts an LWE ciphertext vector into a plaintext vector.

unsafe fn trivially_decrypt_lwe_ciphertext_unchecked(
    &mut self,
    input: &Ciphertext
) -> Plaintext

Unsafely trivially decrypts an LWE ciphertext into a plaintext.

Safety
