Google在MIT发布的难题

刚从cnPhil那儿看到一则有趣的消息:近日,Google Jobs在MIT校园内到处张贴着一份密码,企图在MIT校园里的一群变态中找出几个最变态的破密大牛。密码上面附文说,如果你能破解这份密码,你在Google会很有前途。据说,这份密码包含了一个Google Jobs的电话号码,解开密码的人可以通过此电话留下自己的个人信息。目前,还没有人破解出这段密码来。

    答案揭晓:617-639-0570

  • MITstudent

    Here’s the solution if you are interested:
    “Congratulations Keep Seaching or call 617-639-0570 x10”

    Here’s the mapping of the solution:

    0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ

    456789ABCDE2FGHIJKL0MNOP1QRS3TUVWXYZ

    Here’s how you solve it if you are interested:

    1) Pick out CONGRATULATIONS

    The mapping is pretty straight forward with some gaps in the letters and some ambiguities.

    2) Among the ambiguities are the letters J,O,B,S which map to 0,1,2,3

    3) That resolves the ambiguities and the resulting map above is the logical result.

    617-274-8660
    If that’s the correct answer (which according to a TechCrunch commenter, with working showed, it is), it’s not Google. There’s a voicemail system saying something along the lines of “Congratulations on solving the second, harder puzzle. Unfortunately, we’re not Google, but leave your name and number – you won’t regret it.”

    彻底无语。。。竟然是凯撒替换。。。。。。
    抽空验证了一下,居然只要直接mapping过去就行了

    居然是单纯的移位,费了好大功夫,肯定有人比我快的,压根没往这上面想

    还是python快

    from string import maketrans

    print “8mldq6tui6tfmlrhaanra6q8efldmq86ii2o32s5j13jxoj”.upper().translate(maketrans(“0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ”,”456789ABCDE2FGHIJKL0MNOP1QRS3TUVWXYZ”))

    难在你怎样看出移位的规律

  • fjxmlhx

    说实话看到这个我第一眼就想了凯撒..但是觉得不会那么简单..
    至于为什么..因为我了解的密码学不多..差不多印象最深的就是凯撒.

  • asdf

    有个幻想:用语言模型来解

  • Sacrish

    低调地说,刚看到的时候,我感觉到是替换法了。而且,第一个词十之八九是congratulations。只是我被那些空格成功误导了~~

  • trek jerseys

    恩 好有道理呢!

  • swin

    第一个想法是凯撒替换。不过被空格误导了。我对美国的电话号码也不是很清楚。用凯撒替换可以做出来,但具体是不是正确的还得去试试才知道
