摘要
时变离散时空系统含有大量初始参数,将其用于保密通信设计可加强密钥数量.研究一类时变离散时空系统的混沌性,给出这类时变离散时空系统在Devaney意义下混沌的一些新概念,构造出一类特殊的时变离散时空混沌系统.该结果可拓宽离散混沌系统的研究范围.
Time-varying discrete spatiotemporal systems contain many tunable parameters and are advantageous in the sense of having a sufficiently large key space for designing good security systems. Chaos in a class of time-var-ying discrete spatiotemporal systems is studied. Several new concepts for these systems to be chaotic in the sense of Devaney are given and a special type of such chaotic systems is constructed. To some extent, the new results have expanded the scope of the research of discrete spatiotemporal chaotic systems.
