}

A trait for engines encrypting zero in LWE ciphertext vectors.

Semantics

This pure operation generates an LWE ciphertext vector containing encryptions of zeros, under the key secret key.

Formal Definition

This generates a vector of [LWE encryption] (crate::specification::engines::LweCiphertextEncryptionEngine) of zero.

Required Methods

fn zero_encrypt_lwe_ciphertext_vector( &mut self, key: &SecretKey, noise: Variance, count: LweCiphertextCount, ) -> Result<CiphertextVector, LweCiphertextVectorZeroEncryptionError<Self::EngineError>>

Encrypts zeros in an LWE ciphertext vector.

unsafe fn zero_encrypt_lwe_ciphertext_vector_unchecked( &mut self, key: &SecretKey, noise: Variance, count: LweCiphertextCount, ) -> CiphertextVector

Unsafely encrypts zeros in an LWE ciphertext vector.
