}

A trait for engines functional packing keyswitching (discarding) LWE ciphertext vectors into a GLWE ciphertext.

Semantics

This discarding operation fills the output GLWE ciphertext with the functional packing keyswitch of the input LWE ciphertext vector, under the pksk functional packing keyswitch key.

Formal Definition
