Research on chaotic quantization algorithm and test analysis

This paper described the theory of generating pseudo-random sequence based on the chaotic map in the application of information security,and the performances of some typical quantization methods in one-dimensional chaotic systems were analyzed.The analysis and experimental results demonstrate that some kinds of methods,which were frequently used have some security flaws.So this paper can give some help for the use of chaotic system in the application of information security.Finally,some suggestions for improving chaotic quantization algorithm are proposed in the end.
