In view of Chua's circuit's characters and the deficient in DES algorithm, the paper presents a new image encryption scheme based on DES algorithm and chaotic encryption. The chaotic sequence is implemented in the DES algorithm to improve the initial keys and the iterating operations, so that the chaotic encryption is combined with DES algorithm. Theory analysis and simulation results show that the presented scheme can expand the initial key space, improve the security and anti-attack ability… CONTINUE READING
