摘　　要：传统锯齿混沌存在硬件实现资源消耗较多,参数对输出序列周期影响较大,输出序列随机性不高等缺陷。文章在传统锯齿混沌基础上,构造了一种多维数字锯齿混沌,能有效解决传统锯齿混沌序列表现出的短周期和弱随机性。经测试,基于多维数字锯齿混沌的伪随机序列发生器的硬件实现效率更高,随机性更强,为将其应用于保密通信方案设计提供了基础和条件。Traditional sawtooth chaos has drawbacks such as high hardware resource consumption,significant parameter impact on the output sequence period,and low randomness of the output sequence.This article constructs a multidimensional digital sawtooth chaos based on traditional sawtooth chaos,which can effectively solve the short period and weak randomness exhibited by traditional sawtooth chaotic sequences.After testing,the hardware implementation efficiency and randomness of the pseudo random sequence generator based on multidimensional digital sawtooth chaos are higher,providing the foundation and conditions for its application in the design of secure communication schemes.
