A Novel Chaotic Generator Based On Weakly-coupled Discrete Skewtent Maps
Résumé
In this paper, we propose a novel pseudo chaotic
random number generator based on three weakly-coupled discrete
Skew tent maps. Its implementation was performed with
C language and finite precision N=32, including a chaotic
multiplexing technique. We show that our approach permits to
avoid dynamic degradation caused by finite precision in one hand,
and to allow emergence from chaos toward randomness in the
other hand. As a consequence, the proposed generator turns
out to be secure against famous cryptographic and statistical
attacks. Several statistical tests such as correlation, histogram,
chi2 and NIST have been applied on the generated sequences.
They confirm the robustness of this chaotic generator.
