本文研究动力系统的时间尺度变换。这样的标度函数在系统轨迹的时间轴上操作坐标的改变，保持其相图。利用这一特性，提出了一种通过模拟信道传输二进制信号的混沌加密技术。该方案基于一个合适的时间尺度函数，起到私钥的作用。编码后的传输信号被证明能够抵抗已知的解密攻击，从而提供安全可靠的通信。
The paper deals with time-scaling transformations of dynamical systems. Such scaling functions operate a change of coordinates on the time axis of the system trajectories preserving its phase portrait. Exploiting this property, a chaos encryption technique to transmit a binary signal through an analog channel is proposed. The scheme is based on a suitable time-scaling function which plays the role of a private key. The encoded transmitted signal is proved to resist known decryption attacks offering a secure and reliable communication.
