Abstract :
A secure digital communication system based on chaotic theory is proposed that can resist intrusion of eavesdroppers during the transmission of signals and data. With the master-slave M-synchronization technique, the transmitter and the receiver are designed using the chaotic phase shift keying. Further increasing the complexity of the chaotic dynamics for higher security, a new discrete-time n-scroll attractor model is built based on Chua´s circuit. This methodology for designing secure communication systems can, in principle, be well applied to most on-line communication applications, such as Internet telephone, e-commerce transactions, and digital data transfer
