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: 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;
