Performance Analysis of Chaos based Cryptographic Transmission and Chaotic Synchronization

Applications of multimedia broadcasting and mobile communication are the new generation communication networks which demands for more number of users to be serviced through the network every day. For these multiuser applications transmitted data security is very important in wireless communication network. So in this paper a methodology for the transmission of data using chaotic encryption algorithm is proposed to increase the security of the data. A proposed new structure is based on coupling of chaotic system through a robust synchronization technique called Impulsive synchronization. We combine the text message with the chaotic signals to reduce the attack and improve the security of the data. A new method of impulsive synchronization for a class of chaotic systems is proposed and boundaries of stability region also estimated. The performance of BER in AWGN channel are verified and analyzed with MATLAB toolbox.
