DES encryption algorithm is an important content in the field of information security,but it has a certain defect.In order to improve DES's security performance,a dynamic DES algorithm based on OCML discrete spatiotemporal chaos is proposed.The micro-disturb method was adopted to further improve pseudo-random feature of OCML.Simulation and analysis indicate that the proposed algorithm can obtain a more security performance.
