Description: 代入法的启发示搜索
我的代码实现是：按照自然语言各字母出现频率的大小从高到低（已经有人作国统计分析了）先生成一张字母出现频率统计表（A）--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z)
，再对密文字母计算频率，并按频率从高到低生成一张输入密文字母的统计表（B），通过两张表的对应关系，不断用A中的字母去替换B中的字母，搜索不成功时就回退，在这里回朔是一个关键。

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);) Platform: |
