我们引入了一种利用非线性动力系统特性的非对称（公钥/私钥）加密的新方法。高维耗散非线性动力学系统分布在发射器和接收器之间，因此我们将该方法称为分布式动力学加密（DDE）。发射机动态是公开的，而接收机动态是隐藏的。通过调制发射机的参数来对消息进行编码，这会导致整个系统吸引子的变化。未经授权的接收者不知道接收者中隐藏的动态，并且无法解码消息。我们展示了一个使用耦合映射晶格的 DDE 示例。
We introduce a new method for asymmetric (public key/private key) encryption exploiting properties of nonlinear dynamical systems. A high-dimensional dissipative nonlinear dynamical system is distributed between transmitter and receiver, so we call the method distributed dynamics encryption (DDE). The transmitter dynamics is public, and the receiver dynamics is hidden. A message is encoded by modulation of parameters of the transmitter, and this results in a shift of the overall system attractor. An unauthorized receiver does not know the hidden dynamics in the receiver and cannot decode the message. We present an example of DDE using a coupled map lattice.
