Abstract

Nonlinear stream cipher is a fundamental system in protecting data security in computer networks due to its high level of protection. This type of cipher needs moderate level of calculation to be attacked it by attackers. This research presents an analysis to nonlinear Boolean function and its role in nonlinear generator of sequence keys by using generator algorithm by proposing an algorithm to generate those functions. This algorithm will be simulated to help designers choosing the suitable permutation function.
