Description: 根据设计要求：1）具有文件加密和解密功能；2）具有加解密速度统计功能；3）采用密文反馈链接和密文挪用短块处理技术。我们可以知道，程序要有加密模块、解密模块、子密钥生成模块，这三个模块构成DES算法。DES算法再构成3DES，这很简单，只要加个密钥便可实现。3DES还必须工作在密文反馈连接模式下和使用密文短块挪用技术。至于速度统计功能就很好实现，用文件长度除以处理时间便是加解密速度。-based on the design requirements : 1) with file encryption and decryption function; 2) the speed with the encryption and decryption functions of statistics; 3) Use of dense text links and feedback secret misappropriation short pieces of text processing technology. We know that procedures have encryption module, decryption modules for key generating modules, which constitute three modules DES algorithm. DES algorithm constitute 3DES, this is very simple, as long as add key can be reached. 3DES must also work in close link text feedback mode and the use of short text block secret misappropriation of technology. As for the speed of statistical functions properly achieved, divided by the length of documents with the processing time is the speed encryption and decryption.

Description: VirtualTreeviewVirtual Treeview is a treeview control built from ground up. More than 3 years of development made it one of the most flexible and advanced tree controls available today. Virtual Treeview starts off with the claim to improve many aspects of exisiting solutions and introduces some new technologies and priniciples which were not available before.
As the name already indicates, this control uses a different paradigm for tree management than other controls of this kind. It does not know anything about the data it manages (except its size), not even the captions of a node. Everything is retrieved from the application via events (or descentants via overridden methods).
Virtual Treeview has been carefully designed and thoroughly tested. The control proved its concept as well as everyday fitness already in many commercial products and freeware projects.-VirtualTreeviewVirtual Treeview is a tre eView control built from the ground up.

Description: 一、用表格形式显示字符
1、题目：用表格形式显示ASCII字符
2、实验要求：
按15行*16列的表格形式显示ASCII码为10H-100H之间的所有字符,即以行为主的顺序用ASCII码递增的次序依次显示对应的字符.每16个字符为一行,每行中的相邻两个字符之间用空白符(ASCII为0)隔开.
3、提示：
(1)显示每个字符可能使用功能号为02的显示输出功能调用,使用方法如下:
MOV AH,02H
MOV DL,输出字符的ASCII码
INT 21H
本题中可把DL初始化为10H,然后不断使其加1(用INC指令)以取得下一个字符的ASCII码.
(2)显示空白符时,用其ASCII码为0置入DL寄存器.每行结束时,用显示回车和换行符结束本行并开始下一行.
(3)由于逐个显示相继为ASCII字符时,需要保存并不断修改DL寄存器的内容,而显示空白、回车、换行符时也需要使用DL寄存器，为此可用堆栈来保存相继的ASCII字符。
具体用法是：在显示空白或回车、换行符前用指令PUSH DX把DL的内容保存到堆栈中去。在显示空白或回车、换行符后用指令恢复DL寄存器的原始内容。-a tabular form with a character show, entitled : tabular form showed two ASCII characters, experimental requirements : * 15 by 16 firms in tabular form for the show ASCII des-100H between all characters, that is, to act with the main sequence of ASCII increase in the order corresponding to the sequence of characters. Each of the 16 characters, and his party Each line of the adjacent between two characters with an empty site (ASCII 0) separated. 3, Tip : (1), showing each character may be used for 02 functions, the output function, use the following method : MOV AH, 02H MOV DL, Output ASCII characters INT 21H this issue can be put to initialize the DL 10 H, and then it increases one (using INC. Directive) to obtain under an ASCII characters. (2), showing a blank website , with its ASCII 0 p

Description: 实验内容
1、对称密码技术的实现
（1）熟悉相应的DES加密/解密函数的使用，在单机完成对特定文件（test-1.txt）的单重DES加密/解密；
（2）针对DES密钥特点（8字节，64比特位，其中真正起作用的为56比特位），设计一次一密的密钥产生机制（即每次会话所使用的密钥都是临时随机产生的）；
2、非对称密码技术的实现
（1）熟悉RSA相关函数（公私钥生成函数，加密/解密函数）；
（2）利用公钥加密特定文件（test-1.txt），并用私钥进行解密；反过来，再利用私钥加密特定文件，并用公钥进行解密。对比解密后的文件与原始文件是否一致。
3、信息摘要技术的实现
（1）熟悉MD5算法的实现函数；
（2）利用MD5实现函数，对特定文件（test-1.txt）进行信息摘要的计算，得到信息摘要M1；尝试改变特定文件中的内容（比如改变其中某个字母），再利用MD5计算一次信息摘要，看同之前得到的信息摘要是否相同；
设计要求
1、JAVA语言编程实现
2、单机上完成
3、加密内容为一文本文件（从服务器下载），从服务器上下载相关软件包（jce-1_2_2和帮助文件，主要用于RSA密钥生成和加/解密,如果安装了JDK1.6版本以上，则不需要jce支持）后，请先阅读帮助再进行编程。(DES/RSA/MD5
The implementation of symmetric cryptography
(1) familiar with the use of the corresponding DES encryption / decryption function, complete single DES encryption / decryption of a particular file (test-1.txt) in a single machine;
(2) for DES key features (8 bytes, 64 bits, which really works for 56 bits), the design of a secret key generation mechanism (i.e. using the session key is randomly generated temporary);)

Description: Le monde informatique a connu une grande expansion depuis que les réseaux sans fil
ont vu le jour. Un réseau sans fil permet de lier des terminaux sans liaison filaire. L’existence
de ce type de réseaux a permis plus de mobilité et de flexibilité dans la structuration des
réseaux. Les utilisateurs peuvent se connecter facilement et peuvent se déplacer tout en
gardant la connexion au niveau d’une entreprise, industrie ou maison intelligent. Dans ce
chapitre, nous montrons le cadre théorique sur lequel nous nous sommes basés pour traiter les
différents aspects de la norme Zigbee. On a consacré aux comparaisons des technologies sans
