Expand description

A trait for engines trivially encrypting GLWE ciphertext.

Semantics

This pure operation generates a GLWE ciphertext containing the trivial encryption of the input plaintext vector with the requested glwe_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

Trivially encrypts a plaintext vector into a GLWE ciphertext.

Unsafely creates the trivial GLWE encryption of the plaintext vector.

Safety

For the general safety concerns regarding this operation, refer to the different variants of GlweCiphertextTrivialEncryptionError. For safety concerns specific to an engine, refer to the implementer safety section.
