1. A method, comprising:
generating, with a network node, at least one random object based on an encryption key, wherein the encryption key is used as a seed for a random object generator; and
performing, with the network node, a linear transform of transmit symbols into one or more spatial layers based on the at least one random object generated from the encryption key,
wherein the linear transform is performed between a modulation layer of a physical layer of the network node and a mapping layer of the physical layer of the network node.
