Abstract
Nonlinear behavior seems to be the rule rather than exception in nature, so the progressing in security and cryptography scope is very wide needed in the world. Problem: Cryptographically, there is potential needs to produce the nonlinear products or to complicate the linear system constrains to be as nonlinear system. Problem Solving:Hence, to solve this problem a new nonlinear scheme for general-purpose pseudorandom number generator (Implementing a New Serial Control as Nonlinear Function for Key Stream Pseudo-Random Number Generator) is presented by this research which comprises two parts; the traditional part, as a combination of LFSR, and a serial part as suggested part comprising a new approach of high complexity performance to meet standard cryptographic criteria. Results: practically, a strong cryptographic key stream pseudo-random number generator was obtained in this research which provides a substantial increase of complex nonlinearities, leads to the best development of randomness statistical property output sequences, passed all statistical tests successfully, and has large linear equivalence to prevent correlation attacks.
