Digital Secure Communication based on Customized Protocol
This paper presents a practical solution for secure communication by controlling a multi-chaos system via key-drive technology, and by combining classical encryption algorithm and dual chaos encryption algorithm with additional robust-gain and load-balance control. Signal is first encrypted using chaos random iterative encryption. Then it is further encrypted using chaos key control system. Meanwhile, to protect against attacking based on prediction method, multiple non-linear variation is used to encrypt the modulating signal, which will add new cipher code. For receiver, received signal is decrypted using inverse transition to the sender. Then the decrypted signal is sent to a responsive system designed using discrete system synchronization method based on PC synchronization and feedback synchronization. Finally, the original signal is recovered using chaos iterative decipherer by extracting iteration times and initial value from the decrypted signal.
