Abstract:

In order to overcome the disadvantage of the common chaotic maps for generating pseudo-random number, this paper has analyzed advantages and disadvantages of commonly used methods of chaotic map, and then proposes a hybrid algorithm based on Logistic chaotic mapping and Tent chaotic mapping. The algorithm has a better performance in generating pseudo- random number through analysis and testing.

Key words: Logistic chaos, Tent chaos, pseudo-random number, hybrid chaos
