Description: This book covers cryptographic programming in Java. Java 1.1 and Java 1.2 provide extensive support
for cryptography with an elegant architecture, the Java Cryptography Architecture (JCA). Another set
of classes, the Java Cryptography Extension (JCE), provides additional cryptographic functionality.
This book covers the JCA and the JCE from top to bottom, describing the use of the cryptographic
classes as well as their innards. Platform: |

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；

Description: Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc.) to be encrypted in such a way that decryption becomes a mechanical operation that does not require a computer. One of the best-known techniques has been credited to Moni Naor and Adi Shamir, who developed it in 1994. Platform: |
