Abstract: A certainty random permutation generating algorithm based on chaotic system is proposed,and using this method a high-strength transposition encryption algorithm is proposed.The encryption algorithm can be used as a generic module to join the other cryptographic system in order to improve the system security.And the algorithm is applied to the images and text data encryption.Experiments and tests show that the transposition effect of this encryption algorithm is great,and the encryption speed is fast.So it is a good general transposition method.
