Abstract
A hardware module has a plug to interface with an audio channel of a speech communication device. A scrambler connected to the plug is configured to receive a local audio input signal and form an encrypted audio output signal in a human audible range that is applied to the audio channel of the speech communication device. The scrambler also receives a remote encrypted audio input signal in a human audible range and forms a remote audio output signal corresponding to the remote encrypted audio input signal.
