1.(3-38)本实验练习的目标是实现一种错误检测机制,它使用了本章中介绍的标准CRC算法。请编写两个程序:生成器generator和验证器verifier,生成器程序从标准输入读入一个n位的报文,该报文是由0和1组成的ASCII文本字符串,它是第一行,第二行是k位的多项式,也是ASCII文本。该程序输出一行ASCII文本(到标准输出),其中包含n十k个0和1,代表了要被传输的报文。然后.它也输出多项式,就好像它读入进来时一样。验证器程序将生成器程序的输出读入进来,并输出一条报文,说明它是正确的还是错误的。最后,再编写一个程序alter,根据它的参数(位的顺序号.计算的时候从左向右进行,并且从1开始计数)变反第一行中出参数指定的位.两行字符串中其他的内容完全一致地复制过来。通过输入: generator < file | verifier 你应该看到该报文是正确的,但是,当你输入: generator < file | alter arg | verifier 你应该得到错误的提示信息。

此程序的加密原理是对文件中字符的ASCII码按照先高4位后低4位的次序分别进行加密4次(每加密一次变换一次密匙),加密后将高4位和低4位再合成新字符输入 到加密文件。加密的密匙的变化规律是:新密码为原密码异或上次加密的字符的ASCII码的高4位或者低4位。解密过程是加密的反过程。-This program is file encryption principle characters in the ASCII code in accordance with the first post-high four low-order 4 bits are encrypted 4 times (once for each transformation a key encryption), encryption will be high 4 and low 4-bit again Synthesis of new characters entered into the encrypted files. Variation of the encrypted key is: the new password to encrypt the original password different or the last character of the ASCII code of the high four or low 4. Decryption process is the process of encryption against.
