Cipher Text Optimization System Based on Tree Parity Interactive Learning Machine and Genetic Algorithm
摘要
Abstract
In order to make the encryption system have the optimization performance,and solve these problems such as not achieving the global optimization and low speed of convergence,the cipher text optimization system based on the Tree Parity Interactive Learning Machine( TPILM) and discrete evolution algorithm is proposed in this paper. It defines the weight update mechanism,and couples the chaotic mappings to construct the TPILM and its mutual interference model. It introduces the cutting roulette selection mechanism into the uniform crossover operator. Meanwhile,it takes the adjacent pixels correlation coefficient and the cipher text information entropy of image block, introduces the weight theory to design the fitness function to propose a novel global discrete evolutionary algorithm for firstly applying to image encryption. At last,it produces the encryption structure of“initial optimization-cipher optimization”. Experimental results show that, compared with other encryption systems, the encryption system in this paper has the best quality and the function of global fast optimization to optimize all the iterative outcomes to make the cipher have the maximum information entropy and the lowest correlation coefficient.关键词
