Abstract

An encoding device that includes an encoding engine implemented by a processor connected to a memory. The memory stores a key map that encodes a data signal with a noise signal. The encoding engine is configured to obtain a data signal and generate a noise signal. The encoding engine is further configured to determine a key map byte value at a key map byte location in the key map. The key map byte value indicates a data signal byte location in the data signal. The encoding engine is further configured to determine a data signal byte value at the data signal byte location in the data signal and overwrite a noise signal byte value with the data signal byte value at a noise signal byte location in the noise signal. The encoding engine is configured to transmit the encoded signal.
