HIGH SECRECY COMMUNICATION WITH HYPERCHAOTIC SYSTEM BY USING MOD TECHNOLOGY

A new chaos synchronization and digital communication is proposed.It firstly changes the synchronized signal of encryption into digital signal,then digital signal making shift and an ieor with the keys is transmitted into decryption by open channel,at last synchronizes the decryption with the extracted synchronized signal.After synchronized,one of chaotic signal from encryption making an ieor with plaintext is used in secrect communication.The simulation work indicates that the advantages of this encryption's communication are its high level of security and resistance to,large extensive key's choice,fast encryption speed compared with the same kind of encryption schems.
