Abstract:Synchronization of discrete chaotic systems (i.e. chaotic maps) and its applications in digital secure communications were investigated. These chaotic maps were achieved by designing chaotic neural networks, which are implemented by learning the dynamics of chaotic systems with neural networks. The nonlinear feedback control method was presented to synchronize two identical copies of chaotic neural networks, and a new chaotic secure communication scheme was given based on the synchronization of the networks. The numerical experiments show that the proposed secure communication scheme has advantages of flexible implementation, fast synchronization, high quality recovery information and large amounts of secret key for information encryption.
Keywords:chaotic neural networks  chaotic synchronization  secure communications  speech communications
