Six-dimensional chaos based on signal encryption and image encryption

With the Internet technology and multimedia technology rapid development in recent years,the transmission of digital information has become wide range of ways,can be convenient and efficient transport network,has gradually become an important means of information exchange,so the confidentiality of information more and more attention has been paid.This paper,based on the six-dimensional chaos achieves signal encryption and image encryption method,and the number of iterations and the chaotic signal using addition and subtraction means to set the password for the encrypted information to provide a new method.
