## 数学代写|密码学作业代写Cryptography & Cryptanalysis代考|Edgar Allen Poe

While Edgar Allen Poe is most known for his literary works, he also was an accomplished amateur cryptographer. In 1841, Poe wrote an essay entitled “A Few Words on Secret Writing,” it was published in Graham’s Magazine. In his story, “The Gold-Bug” cryptography plays a central role in the story. While Poe is not known to have done any research in cryptography, nor created any ciphers, he did play a key role in increasing the public interest in the field of cryptography. William Friedman, a cryptographer who lived from September 24, 1891, to November 12,1969 , credited his interest in cryptography to Poe’s story The Gold-Bug. Friedman was the director of research for the Army Signals Intelligence Service in the 1930s. He is also credited with coining the term “cryptanalysis.”

In December 1839, Poe published a challenge in the “Alexander’s Weekly Messenger.” In that challenge he stated he could solve any single substitution cipher than readers could submit. His challenge stated.
It would be by no means a labor lost to show how great a degree of rigid method enters into enigma-guessing. This may sound oddly; but it is not more strange than the well-known fact that rules really exist, by means of which it is easy to decipher any species of hieroglyphical writing — that is to say writing where, in place of alphabetical letters, any kind of marks are made use of at random. For example, in place of $A$ put $\%$ or any other arbitrary character -in place of $B, a^{*}$, elc., elc. Let an entire alphabet be made in this manner, and then let this alphabet be used in any piece of writing. This writing can be read by means of a proper method. Let this be put to the lest. Let anyone address us a leller in this way, and we pledge ourselves to read it forthwith-however unusual or arbitrary may be the characters employed.
From December 1839 to May 1840, he was able to successfully solve all of the ciphers that readers submitted. There was one submitted that he could not break.

## 数学代写|密码学作业代写Cryptography & Cryptanalysis代考|Alan Turing

One cannot tell the story of Enigma without at least mentioning Alan Turing. He is famous for leading the team that was able to crack the Enigma version used by the German Navy during World War II, a story that has been immortalized in the movie The Imitation Game. During World War II, Turing worked for the Government Code and Cipher School that operated out of Bletchley Park. Bletchley Park is 50 miles northwest of London. The mansion and 58 acres where purchased by MI6 (British Intelligence) for use by the Code and Cipher School. A number of prominent people worked at Bletchley Park including Derek Taunt (a mathematician), Max Newman (a mathematician), and Hugh Alexander (a chess champion).

Turing’s impact on the field of cryptography is profound. He led the British team responsible for attempting to break the German naval Enigma. He worked to improve the pre-war Polish machine that would find Enigma settings. He was successful and MI6 was able to decipher German naval messages. This work was considered highly classified. They feared that if the Germans realized that the Enigma had been compromised, they would change how they communicated. Therefore, intelligence gathered via Turing’s team was kept a closely guarded secret and when it needed to be shared with others (such as military commanders), a cover story was given to account for the source of the information. Many sources claim that Turing’s work at Bletchley Park shortened the war by at least 2 years, saving millions of lives.
