Qian Li · Jisuanji gongcheng yu sheji · 2006
A new method for digital color image encryption based on chaotic sequence and DES in cryptography is presented.Combined with the Logistic mapping in non-linear dynamics system,an image encrypting and decrypting algorithm based on DES XOR operation is designed.Firstly,a natural chaotic sequence is created with the key.The image matrix is transformed with this chaotic sequence,using DES XOR operation for scrambling.Then an encrypted image is got.The decrypting operation is a reverse process of encryption.The simulation indicates that the result is satisfying.
