Design of random noise generator using SW algorithm

ABSTRACT

A random noise generator uses a non-deterministic source to produce randomness. Most operate by measuring unpredictable natural processes, such as thermal noise, atmospheric noise, or nuclear decay. Critical cryptography applications require the production of an unpredictable and unbiased stream of binary data derived from a fundamental noise mechanism. In this paper, we proposed a random noise generator with Gaussian noise using filtering algorithm. The proposed scheme is designed to reduce the statistical property of the biased bit stream in the output of a random noise generator.
