Encryption Solutions with Noise Sources

ABSTRACT: Instruments that generate noise waveforms eliminate the need for pseudo-random keys, providing a method that utilizes a truly random signal to strengthen viability against interception. By using a Zener diode in a reverse biased circuit, noise sources can generate random white noise with a constant power spectral density and a Gaussian distribution, referred to as additive white Gaussian noise (AWGN) waveforms. The resulting AWGN-camouflaged transmission will be seen as inconsequential background noise while traveling to its authorized destination. In addition to producing a completely random signal, noise sources also provide a simpler, more efficient process of signal generation when compared to systems that rely upon complex algorithms for data encryption.
