Summary:
A coupled-drivers model was present to improve the fault-tolerance of spatiotemporal chaotic stream cryptosystem. In this model, the driver signals were generated by two coupled chaotic systems, with error detection and correction at the receiver. This model is applicable to all kinds of spatiotemporal chaotic systems base on driver-response synchronization scheme. Theoretical analysis and simulations were given to show the improvement of system's tolerance under channel noise and active attacks. In conclusion, the model present by this article could significantly improve the system’s fault-tolerance without loss on security.
