The aim of the research presented in this thesis is to investigate the use of various optimization heuristics in the fields of automated cryptanalysis and automated cryptographic function generation . in this paper , we improve the design of the cryptographic components using optimization algorithm , and a new approach for attacking on some filter generators is introduced . boolean functions are important parts of sequence ciphers 在應(yīng)用方面,人工智能和機(jī)器學(xué)習(xí)方法在復(fù)雜優(yōu)化和搜索問題中的應(yīng)用是一個受到普遍關(guān)注的研究課題,而人工智能和機(jī)器學(xué)習(xí)方法來解決密碼分析與設(shè)計中存在的復(fù)雜的搜索和優(yōu)化問題也成為近年來密碼學(xué)研究中的一個新興方向。
Second , we discuss the correlation properties and the hamming correlation properties of a number of trace function generation sequences by using systematic ways . we calculate the correlation function of generalized trace function sequences which include no sequences > kasami sequences and kumar - moreno sequences , and we also calculate the hamming correlation function of no sequences ^ kasami sequences and kumar - moreno sequences . at last , we degine the frequency - hopping sequences with optimal hamming correlation properties 其次,用較為統(tǒng)一的工具去研究各種跡函數(shù)生成序列的相關(guān)特性與hamming相關(guān)特性,求出了更廣意義下跡函數(shù)生成序列的相關(guān)函數(shù),這類序列包括了no序列、 kasami序列與kumar - moreno序列;同時求出了no序列、 kasami序列和kumar - moreno序列的hamming相關(guān)函數(shù)值,研究發(fā)現(xiàn)某些具有良好相關(guān)特性的跡函數(shù)生成序列未必具有良好的hamming相關(guān)特性;最后,構(gòu)造了具有最佳hamming相關(guān)性能的跳頻序列族。
