In this dissertation, we mainly use character matrix to research cryptology characteristic of Boolean function and m-ary logic function.Firstly, by using properties of character matrix's row and column we get an equivalence condition of bent function. Then we have an entirely construct method of 4 variable bent function.

本文利用特征矩阵研究了密码学中逻辑函数的相关问题，主要做的工作有：首先，根据Bent函数的自相关特征，利用特征矩阵给出了Bent函数的一个新的等价判别条件，并由此得到了4元Bent函数的一个完全构造方法。

The Atbash Cipher had indeed been part of Sophie's early cryptology training.

埃特巴什码确实是索菲当初接受译码训练的部分内容。

Digital image visual cryptology can not only protect the image information, but also make it stored dispersedly.

这样不仅使得非法攻击者要耗费精力去获取所有恢复保密信息需要的内容，而且使得保密信息拥有者们互相牵制，提高了信息的保密程度。

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。

Block cipher is an important branch of cryptology, it has many attractive features such as high rates, easy for standardization, and efficient for both software and hardware implementations. Block ciphers are usually core components in information and Internet security for data encryption, data signature, authentication and key management.

分组密码是密码学的一个重要分支，它具有速度快、易于标准化和便于软硬件实现等特点，通常是信息与网络安全中实现数据加密、数字签名、认证及密钥管理的核心体制。

The papers are organized in topical sections on probabilistic models, cryptology, pseudo random sequences, quantum models, statistics, probability theory, information measures, error concepts, performance criteria, search, sorting, ordering, planning, language evolution, pattern discovery, reconstructions, network coding, combinatorial models, and a problem section.

文件在概率的模型上被在与目前有关的部分里组织，密码学，假的随机序列，量模型，统计，概率论，信息测度，错误概念，性能准则，搜寻，分类，预订，计划，编码的语言演化，图案发现，重建，网络，组合的模型和一个问题部分。

Quantum cryptology is a new method for secret communications. Compared to the classical cryptography, the greatest advantages of quantum cryptography are provable security and detectives; this is because the security of quantum cryptography is ensured by quantum no-cloning and Heisenberg's uncertainty principle that instead of relying on some complex mathematical problems.

量子密码技术是一种实现保密通信的新方法，它比较于经典密码的最大优势是具有可证明安全性和可检测性，这是因为量子密码的安全性是由量子物理学中量子不可克隆性和Heisenburg测不准原理来保证的，而不是依靠某些难解的数学问题。
