}

A trait for engines transforming LWE secret keys into GLWE secret keys.

Semantics

This pure operation moves the existing LWE into a fresh GLWE secret key.

Required Methods

fn transform_lwe_secret_key_to_glwe_secret_key(
    &mut self,
    lwe_secret_key: InputKey,
    polynomial_size: PolynomialSize
) -> Result<OutputKey, LweToGlweSecretKeyTransformationEngineError<Self::EngineError>>

Does the transformation of the LWE secret key into a GLWE secret key

unsafe fn transform_lwe_secret_key_to_glwe_secret_key_unchecked(
    &mut self,
    lwe_secret_key: InputKey,
    polynomial_size: PolynomialSize
) -> OutputKey

Unsafely transforms an LWE secret key into a GLWE secret key
