Enhancement of Non-Linear Generators and Calculate the Randomness Test for Autocorrelation Property

Abstract

In this paper, three main generators are discussed: Linear generator, Geffegenerator and Bruer generator. The Geffe and Bruer generators are improved andthen calculate the Autocorrelation postulate of randomness test for each generatorand compare the obtained result. These properties can be measured deterministicallyand then compared to statistical expectations using a chi-square test.
