【摘要】 利用加性掩盖和函数调制两种混沌加密方式对模拟信号进行加密,分别从幅值和频率两方面分析加性掩盖方式和函数调制方式,对比两种加密方式加密效果,了解两种加密方式的差异.计算结果表明函数调制方式在幅值和频率的范围上都好于加性掩盖方式的幅值和频率范围,函数调制方式比加性掩盖方式更具安全性.更多还原

【Abstract】 This paper adopted respectively the additive masking mode and the functional encoding and decoding mode to encrypt analog signals. The comparative experiment indicates that the functional encoding and decoding mode is better than the additive masking mode in value & frequency range, and has higher security than the additive masking mode.更多还原
