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.
