把這段密文解成明文
in the same hour came forth fingers of a man’s hand, and wrote over against the candlestick upon the plaster of the wall of the king’s palace and the king saw the part of the hand that wrote. then the king’s countenance was changed, and his thoughts troubled him, so that the joints of his loins were loosed, and his knees smote one against another . the king cried aloud to bring in the astrologers, the chaldeans, and the soothsayers. and the king spake, and said to the wise men of babylon, whosoever shall read this writing, and show me the interpretation thereon, shall be clothed with scarlet, and have a chain of gold about his neck, and shall be the third ruler in the kingdom. then came in all the king’s wise men; but they could not read the writing, nor make known to the king the interpretation thereonf. then was king belshazzar grgatly troubled, and his countenance was changed in him, and his lords were astonished. now the queen, by reason of the words of the king and his lords, came into the banquet house; and the queen spake and said, o king, live forever; let not thy thoughts trouble thee, nor let thy countenance be changed; there is a man in thy kingdom , in whom is the spirit of the holy gods ; and in the days of thy father light and understanding and wisdom , like the wisdom of the gods, was found in him; whom the king nebuchadnezzar thy father, the king, i say, thy father, made master of the madicians, astrologers, chaldeans, and soothsayers; forasmuch as an excellent spirit, and knowledge, and understanding, interpreting of dreams, and showing of hard sentences, and dissolving of doubts, were found in the same daniel, whom the king named belteshazzar; now let daniel be called, and he will show the interetation. the first codeword is othello
上面那個條件沒給出真的很難做,還有其實這種題目很多都是需要一點外界條件的。。。找到了慢慢推就覺得很容易了。。
推理開始:出現(xiàn)最高頻率的字母是X,并且比第二名多了100多個,,,所以X應(yīng)該是E 而Z和S都只出現(xiàn)過一次,所以他們應(yīng)該是X和Z E破譯出來后,發(fā)現(xiàn)有eZ的詞出現(xiàn)。。。那很顯然Z就應(yīng)該是X而不應(yīng)該是Z了。。因為eZ的英語好像沒有。。而eX****的英語好戲那個有不少,,比如“抱歉”的英語就是EX開頭的 所以可以得出Z=X,S=Z
而縱觀全文中有許多的JPX ,已經(jīng)得出X=E了。。。那很明顯就是JPe了。。。而JPe的單詞如不出意外的話應(yīng)該就是the了。。 所以可以得出:J=T,P=H了。。。
只有一個字母的單詞,出現(xiàn)了‘M’和‘B’用一個字母作詞,這和A和I的用法很像。。再根據(jù)I出現(xiàn)在開頭的情況來說。。。得出B=i 而M=a,再看看英語的所有格用法。。可以得出R=s
。。有點累了。。。接下來就可以用以得出的單詞來解出還沒得到的字母了。。。 因為已經(jīng)得出了B=i..而文中出現(xiàn)了多次IT,能出現(xiàn)在開頭的單詞有幾個呢?不就是只有in和if嗎? 而根據(jù)T出現(xiàn)的次數(shù),,,得出100多次。。屬于高頻字母。。。所以應(yīng)該是N。。得出T=N
又看見了RME這個字母。。因為我們已經(jīng)得出了R=s,M=a,所以就應(yīng)該是saE,但是sa*的字母有很多, 有sad/sap/sat/saw/say。t已經(jīng)得出了,可以排除了。。根據(jù)詞的位置基本可以排除掉形 容詞sad,只剩下saw/say/sap/。。怎么辦?很好解決的,找找看有沒有其他的什么擁有E的單詞。??吹搅擞蠮PE,因為J=T,P=H。。。所以得出是thE,把w,y,p帶進去這個單詞到英漢轉(zhuǎn)換詞典里看了一下。。發(fā)現(xiàn)thy是古英語“你”的意思。。而其他的thw,thp都查不到。。因此得出E=y
看了看高頻率的單詞。。只剩下出現(xiàn)了100多次的C沒有對應(yīng)。。而高頻率排行榜中第四的O也沒有人理。。所以設(shè)想下。。。C=O然后又發(fā)現(xiàn)CI的詞很多。。。O開頭的單詞。。好像也只有OF吧。。所以得出I=F。。。
高頻率榜中還剩下一個R。。發(fā)現(xiàn)很多詞的后綴是***XV。。因為X=E。。所以應(yīng)該是ER,得出V=R(其實這就是我最沒把握的地方)
后綴中還出現(xiàn)了很多BTW,B=I,T=N。。很明顯最后一個字母就是G。。所以得出ing。。因此W=G
兩個‘YVCJX’=Yrote。。推理一下。。Y應(yīng)該是等于W
HTCYT’和‘HBTW'R’=‘Hnown’和‘Hing's’。。推理出H就是K
剩下的就不推了:G=l,Q=p,U=u,K=q,A=c,L=m,F(xiàn)=b,D=v。
最后剩下個O~j。
發(fā)現(xiàn)有的單詞出錯,出現(xiàn)一次的‘zoints’和‘belshajjar’都不是單詞,試著將‘z’和‘j’換一下,就正確了,而且后者是圣經(jīng)里的名詞
,還有古英文的thy和thee。應(yīng)該沒問題了。所以最后O=z,S=j(luò),再確定前邊的Z=x。就完了。
