Increasing the quality of pseudo-random number generator based on fuzzy logic

Abstract

We consider previously suggested by authors pseudo-random number generator based on fuzzy logic (FRNG) to increase its quality by increasing the period of generated series. To increase the period of FRNG we include more LFSRs in its structure. At the beginning we will study the case of combining four LFSRs in constructing the FRNG then the case of using eight LFSRs considering the randomness and security of the generated sequences. The resulted new versions of FRNG generate pseudo-random numbers which are more close to true random series that make it more suitable and attractive for many applications such as data security and cryptography.
