摘要

Chaos-based cryptography is widely investigated in recent years, especially in the field of random numbergenerators. The paper describes a novel pseudo-random bit generator (PRBG) based on chaotic logisticmaps. Three logistic maps are combined in the algorithmic process, and a block of 32 random bits isproduced at each iteration. The binary64 double precision format is used according to the IEEE 754-2008standard for floating-point arithmetic. This generator provides a considerable improvement of an existinggenerator in the literature. Rigorous statistical analyses are carefully conducted to evaluate the quality andthe robustness of the PRBG. The obtained results showed the relevance of the proposed generator, whichis suitable even for real-time applications.
