This paper generalizes the conclusion of Perfect nonlinear S-boxes by Nyberg(1991), and introduces the conception of inverse regular generalized vector Bent function. It shows that for inverse regular generalized vector Bent function f with even variables, m is no more than half of?. It also shows that when the input dimension n is odd, the regular generalized vector Bent function and the inverse regular generalized vector Bent function do not exist. This may prevent the cryptology designer from seeking the inexistent function.

摘要该文完善并拓展了Nyberg(1991)的关于广义向量Bent函数性质的结论，相应于Nyberg给出的正则广义向量Bent函数，提出了&负则的广义向量Bent函数&的概念：得到有偶数个输入的负则的广义向量Bent函数输出维数也不大于输入维数的一半；证明了奇数个输入的正则和负则的广义向量Bent函数都不存在，这些结果的给出，可使密码设计者避免一味去寻找某类不存在的函数。

The basic function of county government is to perfect the configuration of market economy system to create basic conditions for the performance of market system by institutional innovation; the guiding function refers to the one that county government creates the development plans, strategies, policies and economic levers to promote the agricultural modernization, county industrialization,and urbanization for driving the county developmant; organizational function means that county government carries out the correct measures of industrial organization to avoid infavorable impact of overcompetition on economy and to improve the development and competitivity; regulatory function performs when county government regulates the conducts of market bodies by economic, legislative and administrative means to solve the externality and to sustain the development; and the complementory function acts on market by government supplying the public goods and harmonizing the social development.

基础性作用即县级政府通过一系列市场化的制度创新，建立完善了市场经济体制的基本框架，为市场机制发挥作用创造了基础条件；主导性作用即县级政府通过发展规划、发展战略、经济政策和经济杠杆，促进农业现代化、县域工业化和城镇化，使县域经济发展更具主动性；组织性作用即县级政府实施正确的产业组织措施，克服过度竞争对县域经济发展的不利影响，提高县域经济运行质量和竞争力；矫正性作用即县级政府通过一系列经济、法律、行政手段，对市场主体的行为进行调节，解决县域经济的外部性问题，使县域经济提高效率，实现可持续发展；补充性作用即县级政府发挥对市场的补充作用，主导公共产品供给，从根本上解决县域公共产品短缺问题，实现经济社会协调发展。

The cultural function is the basic function of education, other functions such as economical function and political function, etc. are refracted in the cultural function of education.

The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.

本文的研究工作主要集中在以下几方面：研究了如何利用混沌映射产生置乱矩阵的方法，给出了基于混沌的数字图像置乱方法，该方法能够将原始图像变成面目全非的杂乱图像，从而保护了数字图像的真实内容；研究了灰级混合函数，提出了基于混沌的灰级混合函数，由于该函数具有混沌特性，所以经过该函数处理后的图像具有非常均衡的灰级直方图；针对图像加密的错误鲁棒性与安全性之间的矛盾，提出了一种含有扩散机制的灰级混合函数。
