Communicating Encrypted Information Based on Synchronized Hyperchaotic Maps

摘要

In this work, a communication scheme to transmit encrypted information based on synchronized hyperchaotic maps is presented. In particular, we appeal to model-matching approach from nonlinear control theory to synchronize two hyperchaotic Rossler maps. An application to secure communication of confidential information is also given. By using a hyperchaotic cryptosystem, we show that output synchronization of Rossler maps is indeed suitable for encryption, transmission, and decryption of confidential information which can be easily implemented on digital computers for use in E-mail.
