低维数字混沌系统的混沌行为严重退化，输出序列周期较短。在本研究中，提出了一种基于高维混沌系统的数字序列发生器，以确保性能和安全性。所提出的发生器资源消耗低，并且数字伪随机输出序列具有大周期。为了避免非混沌状态，分析了高维离散混沌系统的多稳定性。对所提出的数字高维混沌系统的输出序列的统计性能进行了评估，结果表明它是长周期伪随机序列发生器的合适候选者。
The chaotic behavior of low-dimensional digital chaotic systems is seriously degraded, and the output sequence has a short period. In this study, a digital sequence generator based on a high-dimensional chaotic system is proposed to ensure performance and security. The proposed generator has low resource consumption, and the digital pseudo-random output sequence has a large period. To avoid the nonchaotic state, the multistability in the high-dimensional discrete chaotic system is analyzed. The statistical performance of the output sequence of the proposed digital high-dimensional chaotic system is evaluated, and the results demonstrate that it is a suitable candidate for a long-period pseudo-random sequence generator.
