Abstract

Claims (17)

1. An apparatus for Quantum Field Noise Source and Secure Information Transfer Therefrom to realize a true random signal generator (TRSG) for application in secure encrypted communications and/or secure interconnected computer information systems, and spread spectrum-like modulation for secure/stealth communication systems, without the need for a key to decipher encrypted information,

COMPRISED OF

a plurality of Quantum Field Noise Source cells (“QFNS CELLS”) in the form of a plurality of electrostatically-actuated microelectromechanical beams (“MEMS beams”) disposed above and across a slotline to create parallel-plate cavities;

said cavities are delimited by the at least one MEMS beam, actuation electrodes and the slotline beneath said cavities;

the relationship between the MEMS beam-to-slotline distance (d 1 ) and the MEMS beam-to-electrode distance (d 2 ) is d 1 <d 2 /3;

said plurality of MEMS beams have a mechanical resonance frequency, ω c , and are driven by a sinusoidal voltage waveform (the “RF Pump”) of peak amplitude V rf and frequency Ω rf , whose DC level is set to a voltage VCntrl and is applied to the plurality of MEMS beams through a parallel RLC circuit of resonance frequency Ω 0 ;

wherein, an input signal applied to the slotline propagates down the slotline and is influenced by the plurality of MEMS beams disposed above and across the slotline, whose random vibrations, in turn, modulate the signal across the slotline to create white noise; and

wherein by fabricating the apparatus with the same layout, frequencies, beam sizes, and materials, said white noise is decipherable without the need for a key.

2. The apparatus of claim 1 , wherein the thicknesses of the slotline and the actuation electrodes are unequal.

3. A method for Quantum Field Noise Source and Secure Information Transfer therefrom utilizing the apparatus of claim 1 , comprising the steps of:

disposing a plurality of Quantum Field Noise Source cells (“QFNS CELLS”) in the form of a plurality of electrostatically-actuated microelectromechanical beams (“MEMS beams”) above and across a slotline to create parallel-plate cavities;

delimiting said cavities by the at least one MEMS beams, actuation electrodes and slotline beneath said cavities;

setting the relationship between the MEMS beam-to-slotline distance (d 1 ) and the MEMS beam-to-electrode distance (d 2 ) to d 1 <d 2 /3;

setting a mechanical resonance frequency, ω c , to said plurality of MEMS beams driven by a sinusoidal voltage waveform (the “RF Pump”) of peak amplitude Vrf and frequency Ω rf , whose DC level is set to a voltage VCntrl and is applied to the plurality of MEMS beams through a parallel RLC circuit of resonance frequency Ω 0 ;

applying an input signal to the slotline which propagates down the slotline and is influenced by the plurality of MEMS beams disposed above and across the slotline, whose random vibrations, in turn, modulates the signal across the slotline to create white noise; and

fabricating an apparatus copy with the same layout, frequencies, beam sizes, and materials as the original apparatus so that the resulting white noise from both apparatus is decipherable without the need for a key.

4. The method of claim 3 , wherein the thicknesses of said slotline and actuation electrodes being unequal.
