Henon CSK Secure Communication system Using Chaotic Turbo Codes

In this paper,the authors design a novel chaotic secure communication system,which has high security and good error-correcting capability,Firstly,the Henon Chaos Shift Keying (CSK) modulation block is presented.Secondly,Chaotic turbo encoder/decoder(hard-decision)is introduced.Thirdly,this chaotic secure communication system,which comprises the Henon CSK modulation block and chaotic turbo encoder in a serially concatenated form,is shown.Furthermore,a novel two-step encryption scheme is proposed.which is based on the chaotic turbo encoded Henon CSK secure communication system.
