A Color Image Encryption Algorithm Based On Improved DES

摘要：

　　Key space will be reduced after using the traditional DES algorithm to directly encrypt color images.Through combining the chaotic capability of the logistic function and by means of a specific algorithm,the fake chaotic son key’s space which is produced by the logistic chaotic pseudo-random function could be acquired.Then use the key generation algorithm to replace the traditional DES key generation algorithm.Experiment illustrates that the proposed algorithm has stronger robustness and anti-jamming capability to noise,and larger key’s space,sensitive initial keys,and better encryption effect,meanwhile it is better immune to multiple attacks.
