A novel algorithm for evolving encryption sequences based on particle dynamics

In this paper a novel algorithm for evolving encryption sequences based on particle dynamics is presented to design encryption systems with high safety and efficiency. Because the algorithm based on particle dynamics 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 produced has high randomicity, more chaos and long periodicity. The experiments show that the sequence encryption by using this method has high randomicity, and the encryption system by using this method has better security and safety.
