An efficient pseudo chaotic number generator based on coupling and multiplexing techniques

Résumé

Cryptosystems require a very good and secure source of randomness for their security. Such a source is extremely difficult to obtain in practice. Hence, developing a secure pseudo-random number generator reveals necessary. In this paper, we propose a new pseudo chaotic number generator. The proposed structure integrates three discrete chaotic maps: PWLCM, Skewtent and Logistic, which are weakly coupled and implemented with finite precision N=32 bits. It also includes a chaotic multiplexing technique. The experiment results and statistical analysis prove the robustness of the proposed generator as well as its efficiency in terms of computation time in comparison with know chaotic generators of the literature. Based on the previous structure, a random number generator that uses Linux generator has been designed : "/dev/urandom".
