Expand description

A trait implemented by types embodying a GLWE ciphertext.

A GLWE ciphertext is associated with a KeyDistribution type, which conveys the distribution of the secret key it was encrypted with.

Formal Definition

GLWE ciphertexts generalize LWE ciphertexts by definition, however in this library, GLWE ciphertext entities do not generalize LWE ciphertexts, i.e., polynomial size cannot be 1.

Associated Types

The distribution of the key the ciphertext was encrypted with.

Required methods

Returns the GLWE dimension of the ciphertext.

Returns the polynomial size of the ciphertext.
