摘要
跳时加密技术是通过对不同用户采用不同的跳时码序列来实现数据加密,所选择的跳时序列性能的优劣直接关系到整个信息传输系统的安全性能。以同余理论为基础,针对一次跳时序列(即伪随机序列)、二次跳时序列的算法和相关结论,进行了相应算法的加跳和解跳的软件仿真,分析比较了典型的跳时序列的加密性能,提出的多次同余算法实验的结论值得关注。
Hopping encryption technology uses different hopping sequences to achieve data encryption by different users, so the choice of hopping sequence performance is directly related to the security of the information transmission system. In this paper, based on the theory congruence for a hopping se- quences （ or pseudo - random sequence） , the second hopping sequences of the algorithm and the related conclusions, software simulation is made for the corresponding algorithm plus jump and reconciliation. A brief comparison and analysis are made on the performance of the hopping sequence of encryption, The conclusion on repeated experiment with the remaining algorithms is finally reached.
