Design of high efficiency non-linear keys generator based on shift registers

Abstract EN

This paper introduces new key generator, based on Linear Feedback Shift Register (LFSR) as a basic unit and work within stream cipher systems, called a High-Efficiency Non-linear Shift Register Generator (HENSRG).

This generator used nonlinear functions in order to increase the general complexity; also test the efficiency of it by applied the basic efficiency criteria .It's important to observe that this generator passes all these criteria because of its good randomness and complexity.
