标题:

密文:xlxohzhpytkmxbqionlyiyrclkjgff

提示:

小明忙着网上聊天,学过入门就可以用了。他可以协商质数得到双数,最少也是他想要的。

小红随机选一个七,小明发若干个一。弗吉尼亚安全了。请破解,仔细思考。

分析:

首先可以通过“弗吉尼亚是安全的”来判断弗吉尼亚算法用于加密,

然后,“协商素数得到双倍”,得到第一个数11。下一句“最小本原根指向”暗示11的最小本原根是2,DH算法可以从本原根想到。而“小红随机选了一个7”,小红选了一个随机数7,算出来的Y=7。小明返回多个1,表示Y'=8,则可以计算步长k=2。

嗯,在这里,弗吉尼亚密码在线解密工具用于获取最终明文,如下所示
