TLDR
A new method for asymmetric (public key/private key) encryption exploiting properties of nonlinear dynamical systems distributed dynamics encryption (DDE) is introduced using a coupled map lattice.Abstract:
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 latticeread more
