摘要：In this paper a new block encryption algorithm is proposed by combining the one dimensional discrete chaotic map(Logistic map) and SPN structure. The algorithm has introduced chaotic theory into S-boxes and P-boxes respectively and fully utilized the character of chaotic system, such as Pseudo-random, unpredictable track and sensitive initial condition, to make sure that S-boxes have good confusion effects and P-boxes have good diffusion effects. The cryptographic algorithm has been analyzed, and the experimental results indicate that this algorithm satisfies the strict avalanche criterion and a larger key space. Furthermore, the algorithm has good security features and better performance. Meanwhile, the advantages and disadvantages of S-boxes and P-boxes are also considered in this paper. To make sure the algorithm has effective computation ability, we apply them into the iteration of the system flexibly. ? 2010 IEEE.
