Description: 完成基于公钥证书的非对称密钥分配工作
说明：
（1）作为通讯的双方A和B，都有一个共同信赖的第三方CA，由CA为每个人生成公钥证书和相应的私钥并分发给A、B。
（2）A和B分别将自己的公钥证书提供给对方后，分别在本地验证对方公钥证书是否可靠（假定A、B已经获得CA的公钥），然后A用B的公钥加密一个数据X（整型，可自己定义，比如100）并发送给B，B用自己的私钥解密后得到数据X，然后按协商好的函数F（比如F(X)=2*X）计算得到F(X)，再利用A的公钥加密后发送给A；A在本地用自己的私钥解密后得到F(x)，在同本地计算得到的F(X)进行对比，如果一致，说明公钥分配成功。
（3）A用B的公钥对一图象文件（test_pig.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T1；-Complete the asymmetric public key certificate-based key distribution work
Description:

Description: 完成集中式对称密钥的分配工作
说明：作为通讯的双方A和B，都已经分别和KDC拥有会话密钥Ka和Kb，但A、B之间事先没有保密通道，需要依赖KDC为它们的会话分配临时密钥Ks。在完成会话密钥Ks的分配后，A利用Ks对特定文件（test-1.txt）进行加密，并发送给B；B利用Ks对密文进行解密，并对比解密后的明文信息同原来的文件是否一致。

（1）JAVA语言编程实现，基于DES完成对称密码技术的加/解密（JAVA有库函数支持）；
（2）通信内容为一文本文件（test-1.txt）；
（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，KDC可以部署在其中一台主机上或第三台主机上）；
（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KDC的集中式密钥分配方案为参考，完成从步骤1到步骤5的全过程；-Complete centralized allocation symmetric key
