1. A transmitter device for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, collectively or individually configured to:
modify, based at least in part on a secrecy key, an output of orthogonal frequency division multiplexing (OFDM) tone mapping for a physical control channel signal, resulting in a secured physical control channel signal; and
transmit, to a receiver device, the secured physical control channel signal.
