Abstract :
The research presents a proposed method to compute or determine the linear equivalence of the key-stream sequences in stream cipher systems by using periodic sequence property of the Z- transform. This proposed method enables us to compute the linear equivalence of any periodic sequence produced from linear or nonlinear key-stream generators and accurate results are obtained.
