A Method for Generating Chaotic Key Stream
Hu Han · Chinese Journal of Computers · 2004
This paper proposed a method for generating chaotic key stream based on the chaotic map and a fast algorithm to implement it. This method divides the chaotic attractor into 2 n symmetric sub intervals, samples from the chaotic orbit every n time intervals, and gets the independently and uniformly distributed 2 n phase key stream. The theoretical and numerical analyses show that the sequence also has a high complexity. This method can be used in fields such as cryptography, numerical simulation and spread spectrum communication, etc.
