Systems and methods for securing orthogonal frequency division multiplexing (OFDM) transmission of data are discussed herein. Computing devices can sense the signal strength of frequencies on an OFDM wireless channel. The computing device can determine which of the frequencies are fading frequencies failing below a threshold. A transmitting computing device can send artificial data on the failing frequencies and genuine data on the remaining frequencies. Artificial data can be designed to mitigate peak-average-power ratio (PAPR) to have an additional benefit without using extra resource.
