摘要
对时空混沌理论及应用现状进行了简述,研究了时空混沌的数学模型及其应用,提出了一种基于时空混沌的耦合映象格子模型的序列密码算法,并在DSP上加以实现.理论分析和安全性测试实验结果均表明,该算法较之基于低维时间混沌的序列密码算法,具有更高的安全性,应用性较好.
Investigated the mathematical models of spatiotemporal chaos and their applications. Proposed the stream cipher algorithm based on spatiotemporal chaos in coupled map lattice model and implemented it on DSP. Both the theoretic analysis and the attack experiment results indicated that the algorithm is more secure than stream cipher algorithm based on low dimensional temporal chaos. Besides of this, it is also well applicable.
