A sequence encryption producing system based on particle dynamical evolutionary algorithm

In this paper a sequence encryption producing method is presented based on particle dynamical evolutionary algorithm (PDEASE) to design encryption systems with high safety and efficiency. Because the particle dynamical evolutionary algorithm is constructed by using the law of entropy increasing and the principle of energy minimum of particle systems, it has features of uniformity and diversity in particle distribution of particle systems. Therefore, the sequence encryption system produced by using particle dynamical evolutionary algorithm has high randomicity, more chaos and long periodicity. The experiments show that the sequence encryption produced by using this method has high randomicity, and the encryption system by using this method has better security and safety.
