| 摘 要： | 本文针对一种特定的离散时间混沌序列─—帐篷映射序列，讨论了其数字发生方法及其相关特性，提出了将帐篷映射序列用于保密通信的具体应用，结果表明，经二值量化的映射序列具有较理想的相关特性，将其作为加密序列，可获得较理想的保密特性，即使校长的明文－密文对被截获，也难以破译整个加密通信系统。

| Abstract: | This paper deals with a special kind of time discrete chaotic sequence, named Kent-Map se-quence. The digital generating methods and the correlation properies of Kent-Map sequence are dis-cussed. Application of chaotic sequence to security communieations is proposed. Siniulation resultsshow that the binary quantized Kent-Map sequence possesses a good correlation proporty. By applyingthe quantized Kent-Map sequence as cipher, the security can be guaranteed even if segments of plain-text-ciphertext peirs are intercepted. |
