Abstract

In order to overcome the degration of chaotic and improve the randomness of the sequence, this paper proposed a new method of generating pseudo-random numbers based on logistic chaotic mapping. It used four one-dimensional logistic chaotic maps. Each iteration randomly selected one to perturb the other three logistic maps, adding variable parameters and randomly grouping them dynamically to improve the randomness of the sequences. Meanwhile, it enlarged the period of sequence and avoided recurrence of sequences. The pseudo-random number generator is easy to implement by software. The sequence can pass the NIST SP800-22 randomness test. It has good randomness and can apply in the field of information security such as secure communication.
