混沌系统的时间标度:在保密通信中的应用

Time Scaling of Chaotic Systems: Application to Secure Communications

Donatello Materassi, Michele Basso

摘要:

本文研究动力系统的时标变换。这样的缩放函数操作系统轨迹的时间轴上的坐标的改变,从而保持其相图。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。该方案是基于一个合适的时间缩放功能,发挥了私钥的作用。经证明,编码的传输信号可以抵抗已知的解密攻击,提供安全可靠的通信。

英文摘要:

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.
