The multimedia information, especially video and audio information, regarded as a common data stream, with the traditional encryption technology encrypted, ignoring the characteristics of multimedia data, has some limitations. On the other hand, chaotic sequences have several good properties including the ease of their generation, their sensitive dependence on their initial condition and so on. Therefore, this paper discussed image encryption arithmetic on the basis of chaotic sequences through dispersing the real number value chaotic sequences into symbol matrix and transformation matrix, and then encrypted the image. Preliminary results proved that the image encryption arithmetic based on chaotic sequences possesses the traits, namely fast speed for encryption speed, perfect results for encryption.
