世界上至今未解的著名密碼

Codes have done everything from transmitting crucial information during World War II to keeping little brother from snooping in your diary. Here are some that have remained uncrackable.

密碼在二戰(zhàn)期間是交戰(zhàn)雙方慣用的軍事手段，使用密碼不僅可以傳遞重要信息，還可以防止身邊的人窺探你的日志。但仍有一些著名密碼至今仍未破解。

The Zodiac Killer's codes 十二宮殺手密碼

It's been 40 years since the serial killer terrorized the San Francisco Bay Area. The murderer sent letters to the newspapers and police, and four contained coded messages. Only one was cracked. Mental Floss notes that the 408-character code -- deciphered by Donald and Bettye Harden -- contained mistakes and spelling errors, possibly making the other three messages so difficult to untangle.

自連環(huán)殺手恐怖襲擊舊金山港灣區(qū)已經(jīng)過去了40年。殺手給當?shù)貓蠹埡途於监]寄了信件，其中有4封信件都含有編碼信息。其中只有一封被成功破解。Mental Floss注解道，由著名密碼破譯專家Donald 和Bettye Harden破解的這408個字符中包含錯誤字符和拼寫錯誤字符，這使得其他三封編碼信件很難被破解。

But amateur cryptanalysts still try to break the codes: Last year Corey Starliper, a Zodiac-killer obsessive, said he figured out the toughest one, even though police and experts dismissed his claim. If you want a challenge, check out this Web tool that allows you to take a crack at the cipher yourself.

但是，非專業(yè)破譯專家仍在試圖破譯這些密碼：去年，一位名叫Corey Starliper十二宮殺手聲稱他解開了其中一個最難破譯的編碼信息，但是警察和專家并未予以理會。如果你想要挑戰(zhàn)，可以使用網(wǎng)絡工具進行嘗試。

Shugborough inscription Shugborough碑文

A simple sequence of letters is all it is: O U O S V A V V is carved between the letters D and M on the 18th-century Shepherd's Monument located at Shugborough Hall in Staffordshire, England. The monument was commissioned by Thomas and Admiral George Anson, and the letters have never been fully explained, therefore having the dubious honor of being one of the great unsolved cipher texts.

在英格蘭斯塔福德郡的Shugborough，有一座18世紀的牧羊人紀念碑。紀念碑上的碑文是一串被簡單排序的字母：O U O S V A V V，這些字母被刻在字母D和字母M之間。這座紀念碑由Thomas 和Admiral George Anson建造，而紀念碑上從未被解釋清楚的碑文也因此成為了世界上最難解的密碼之一。

Theories abound. The inscription has been thought to be a love letter to Anson's wife, an abbreviated Latin phrase, and even a link to the Priory of Sion -- a code that would lead to the Holy Grail. Dan Brown's novel, "The Da Vinci Code," had a similar idea, prompting new interest in the inscription. But so far, nobody has cracked it, not even Tom Hanks.

關于這一密碼，眾說紛紜。有人說上面的碑文是寫給Anson妻子的一封情書，那一串字母是一句用縮略語書寫的拉丁文，有人甚至說與錫安會有關——它是一串通向圣杯的密碼。Dan Brown的小說《達芬奇的密碼》中也提到了這串字母，重新激發(fā)了人們對這串碑文的興趣。但是，至今為止，沒有人能夠破解這串字母，甚至Tom Hanks也不例外。

Kryptos 克里普托斯代碼

In 1990, a sculpture was created for the CIA that incorporated four encoded messages as a challenge to the employees at the agency. While people at various organizations, including the CIA and NSA, have said they have solved three of them, the fourth remains the toughest to decipher, since it contains only 97 or 98 characters.

1990年，有人為CIA打造了一座包含四條編碼信息的雕像，以此來考驗CIA的特工們。雖然在各類機構如中央情報局和國家安全局工作的人員說他們已經(jīng)破解了其中的三條，但是僅僅包含有97或98個字符的第四條信息卻成了世界上最難解的編碼之一。

Richard Feynman's challenge ciphers 理查德·費曼的挑戰(zhàn)密碼

In 1987 physics professor Richard Feynman received three encoded messages from a fellow scientist at Los Alamos, California, and shared them with his graduate students. Only one of the three has ever been solved. It turned out to be the opening lines of Chaucer's "Canterbury Tales" written in Middle English. The unsolved puzzles are posted here.

1987年，物理學家理查德·費曼收到了從加利福尼亞洛斯阿拉莫斯的一位科學家發(fā)來的三條編碼信息。其中只有一條信息被破解，這條信息原來是用中古英語書寫的喬叟著《坎特伯雷故事集》的開篇幾句。
