Ping Liu · Computer and Modernization · 2013
The sequence generated by chaotic system has better pseudo randomness.DES algorithm implements effectively the diffusion and confusion in the cryptosystem.This paper makes full use of the excellent features to propose a digital image encryption algorithm based on chaos theory and DES.Experimental results show that the encryption algorithm has strong sensitivity to the key,so it can improve the security of digital image in storage and transmission.The algorithm can also solve effectively the problems existing in the spatial domain and frequency domain.
