The literature of cryptography has a curious history. Secrecy, of course, has always played a central role, but until the First World War, important developments appeared in print in a more or less timely fashion and the field moved forward in much the same way as other specialized disciplines. As late as 1918, one of the most influential cryptanalytic papers of the twentieth century, William F. Friedman’s monograph The Index of Coincidence and Its Applications in Cryptography, appeared as a research report of the private Riverbank Laboratories [577]. And this, despite the fact that the work had been done as part of the war effort. In the same year Edward H. Hebern of Oakland, California filed the first patent for a rotor machine [710], the device destined to be a mainstay of military cryptography for nearly 50 years.

7279键盘程序 设0--9数字键，A--F功能键 开机时在最高位显示‘P’ 第一次按数字键在最高位显示数据，第2次按数字键在最次位显示数据，。。。。。。第8次按数字键在最低位显示数据 第9次按数字键在最高位显示数据。。。。。。按任意功能键则系统回到初始状态。

java中大部分对图形、文本、图像的操作方法都定义在Graphics类中，所以此次实验使用的方法如Color(int r, int g,int b), setColor(Color c),drawline(int x1,int y1,int x2,int y2)等都来自Graphics类中，此外对文本和字体的处理还用到了Font类中的 new Font(“字体名”，字体风格，字体大小)，setFont（Font f）等方法；
