密码的

This paper proposes the research situation of the programmable cryptographic technique and the charac teristics of the programmable cryptograph,including the aspects to be concerned about in the development of the programmable cryptograph.

文中给出了可编程密码技术的研究现状，可编程密码的特点，及在开展可编程密码研究时应注意的问题。

Marian Adam Rejewski (help·info; 16 August 1905 – 13 February 1980 was a Polish mathematician and cryptologist who in 1932 solved the plugboard-equipped Enigma machine, the main cipher device used by Germany.

在进行这项工作期间，他从根本上发展了密码分析学。之前，密码分析方法利用自然语言中的模式与统计特性，例如字母的频率分析。然而雷耶夫斯基在他对Enigma密码的攻击中第一次应用了纯数学的方法。

An almost perfect nonlinear exponential permutation with high algebric degree is proposed, with some discussion on how to select the parameters of such permutation. The experimental result shows us a conjecture that there exists no such permutation over even dimensional space.

作者所取得的主要研究结果如下：(1)讨论了分组密码的条件攻击和技术攻击方法；全面总结了分组密码算法设计应当遵循的七项准则；概括了分组密码的四种强化技术；设计了一种新的三重加密方案NTE。

The diffusion structure has important impact on the rate of the diffusion and safety intensity for block cipher.Using the linear transform which has branch numbers as large as possible as the diffusion structure is a main method to devise block cipher.The linear transform is usually achieved by constructing the invertible matrix.

扩散结构的好坏直接影响了分组密码的扩散速度和安全强度，以分支数尽可能大的线性变换为分组密码算法的扩散结构是设计分组密码的一种重要方法，线性变换的构造可通过可逆矩阵的构造完成。

A real-world example, he says, is having to learn a new computer password every few months: As your brain suppresses the memory of the old password, it gets easier to summon the new one.

他说，一个现实生活中的例子是每隔几个月就要记忆新的电脑密码。如果你的大脑压制了对旧密码的记忆，就会更容易想起新密码。

The program also includes a password generator that can create secure 'speakable' passwords and passwords based on user defined templates.

该软件还包括一个可以创建安全的'可读'密码以及根据用户定义的模板生成密码的密码生成器。

It features character selection and density controls, advanced masks and password templates, words and custom strings in passwords, full database support, and pronounceable password generation.

该软件特别推出字符选择和密度控制，高级掩码和密码模板，在密码当中的单词和定制字符串，完全数据库支持，以及生成可发音的密码的功能。

At the same time,select three issues carries on solve by the Year 2008's ACM\ICPC finals:air condition machine is description the elbow of air conditioning installation problem,limited the quantity and types of air-conditioning pipe under the conditions of the installation of air-conditioning method;Password suspects,this problem is giving a system password letter combinations possible combinations and length under the conditions,to design an algorithm to calculate the correct arrangement of the password;Steam roller,this problem giving the situation of urban streets,drive steam roller from one point to another point of the shortest path,is used by how many time.

同时，选取了2008年度ACM\ICPC总决赛的三道题目进行求解：空调机器这一题描述的是对空调管的安装问题，在限定空调管数量和型号的条件下空调管可能的安装方法；密码嫌疑这一题求解的是在给定一个系统密码的可能的字母组合和长度的条件下，设计一个算法以算出正确的密码的排列方式；蒸汽压路机这一题是在给出城市道路情况的条件下，求两点间压路机走完最短路径总共所花费多少时间的问题。

The user creates a database account and a password after installation, based on which, the Password Safe generates a database, in which any number of data records consisting of names, passwords and remarks that can be freely formated as well as any number of user-defined fields can be stored.

用户创建一个数据库的帐户和密码，安装后，在此基础上，密码的安全产生一个数据库，在其中任何数量的数据记录构成的名称，密码和言论可以自由格式，以及任何数量的用户定义的字段可以被保存。

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。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
