Claim 13:
14. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory including computer program code,
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
receive one or more spatial layers, wherein transmit symbols on the one or more spatial layers are mapped to the one or more spatial layers based on at least one random object generated from an encryption key; and
perform an inverse linear transform of soft samples of the one or more spatial layers based on the encryption key and a manner in which a linear transform was performed,
wherein the inverse linear transform is performed between a de-mapping layer and a demodulation layer of a physical layer stack.
