[JSP/Java] InfoSecurity DL : 1: 完成分布式对称密钥分配说明：作为通讯的双方A和B已经共享一个会话主密钥Km。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。要求：（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）；（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分布式密钥分配方案为参考，完成从步骤1到步骤3的全过程；-Complete distributed symmetric key distribution Description: As both A and B have shared a communication session master key Km. After the completion of the distribution of the session key Ks, A specific file using Ks (test-1.txt) encrypts and sends B B using Ks to decrypt the ciphertext, and the decrypted plaintext comparison with the original whether the files are consistent. Requirements: (1) JAVA programming language, based on DES symmetric cryptographic techniques to complete the encryption/decryption (JAVA there are library functions support) (2) the contents of a text file to communicate (test-1.txt) (3) based on the network completion of key distribution work (both as a communications A, B should be deployed on two hosts) (4) are all assigned to the symmetric key one-time pad, randomly generated (5) the specific key distribution process please textbooks distributed key distribution scheme as a reference, complete step 1 to step 3 in the whole process
