Qian Li · Journal of Zhejiang Wanli University · 2010
In this paper,we proposed a new method for digital color image encryption based on chaotic sequence and DES in cryptography.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,to obtain an encrypted image.The decrypting operation is the reverse process of encryption.The simulation indicates that the proposed algorithm can get satisfactory results.Finally,the characteristics and effects of the algorithm are summarized and the aspects of the subsequent work are discussed.
