A voice scrambler system (10) for encryption of a voice signal is provided. The voice scrambler system (10) includes a first generator (124) for generating a fixed frequency signal. A second generator (132) is provided for generating a plurality of frequency signals. Control circuitry (134) is provided for dynamically controlling the second generator (132) for randomly generating the plurality of variable frequency signals. A mixer (122) heterodynes the voice signal with the fixed frequency signal generated by the first generator (124). A filter (126) filters the output of the first mixer (122). An adder (128) adds the voice signal and the output of the first filter (126). A second mixer (130) heterodynes the output of the adder (128) with one of the plurality of frequency signals generated by the second generator (132). A second filter (136) filters the output of the second mixer (130) to generate an encrypted voice signal.
