Abstract:
In this paper, we propose a new key generator based on Linear Feedback Shift Register as a basic unit, the proposed generator acts in stream cipher systems. In order to increase the general complexity, the proposed generator used nonlinear functions. To test the efficiency of the proposed key generator, we applied the basic efficiency criteria.This generator passes all these criteria because of its good randomness and complexity so, it’s called a High Efficiency Non-linear Shift Register Generator (HENSRG).
