Description: 标准C++/C处理BMP图像，没有使用VC中的BITMAP类及任何不在ANSI-C中的结构和函数。采用了k_means压缩算法处理24bit（可以更改源码使之支持8-bit,16-bit和灰度bmp）源码注释详细，其中对BMP文件BMPHEADINFO的处理比较有趣。
new.cpp---->主要的程序代码
*.h----->一个产生U(0,1)随机数的发生器，相合度较小，DES函数产生。-Standard C++/C handle BMP images, do not use the VC in the category and any BITMAP not ANSI-C in the structure and function. K_means compression algorithm used to deal with 24bit (you can change the source code to support the 8-bit ,16-bit and grayscale bmp) detailed source notes, in which the handling of BMP files BMPHEADINFO more interesting. new.cpp----> the main program code*. h-----> generate a U (0,1) random number generator, a smaller degree of consistency, DES Function Generator.

Description: 完成基于非对称密码技术的对称密钥分配工作
说明：
（1）在完成上述基于公钥证书的非对称密钥分配工作的基础上，根据教材上基于非对称密码技术的对称密钥分配方案，完成对称密钥Ks的分配工作。
（2）A用Ks对一图象文件（test_pic.bmp)进行加密并发送给B，B收到后解密，对比原图象看是否一致，并记录整个加密/解密的所用时间T2；
（3）对比T1和T2；
要求：
（1）JAVA语言编程实现，基于RSA完成非对称密码技术的加/解密，基于DES完成对称密码技术的加/解密（JAVA有库函数支持）；
（2）通信内容为一图象文件（test_pic.bmp)；
（3）基于网络完成密钥分配工作（作为通信的双方A、B应部署于两台主机上）；
（4）所分配的对称密钥皆为一次一密，随机产生；
（5）具体密钥分配过程请以课本中基于非对称密码技术的对称密钥分配方案为参考，完成从步骤1到步骤4的全过程；
