Quotes About Codebreaking

Figure 6 The science of secret writing and its main branches.

Polský úspÄ›ch v prolomení Enigmy byl dán tÃ…â"¢emi faktory: strachem, matematikou a Å¡pionáží.

NaÅ¡tÄ›stí nahoÃ…â"¢e nevÄ›dÄ›li, že Turing je homosexuál, jinak bychom také mohli prohrát válku.

The Vigenère cipher was called "le chiffre indéchiffrable," but Babbage broke it;

Codebreakers are linguistic alchemists, a mystical tribe attempting to conjure sensible words out of meaningless symbols.

John Cecil Masterman:

In World War II, a British mathematician named Alan Turing led the effort to crack the Nazis' communication code. He mastered the complex German enciphering machine, helping to save the world, and his work laid the basis for modern computer science. Does it matter that Turing was gay?

While the Germans intercepted and recorded many hours of SIGSALY transmissions, they were never able to interpret them.

This apparently innocuous observation would lead to the first great breakthrough in cryptanalysis.

Alan Turing is such an amazing, tragic story.

CRYPTOLOGY, as the union of cryptography and cryptanalysis is called.

The barriers placed in his path (working his way through the Cryptonomicon, breaking the Nipponese Air Force Meteorological Code, breaking the Coral naval attache machine cipher, breaking Unnamed Nipponese Army Water Transport Code 3A, breaking the Greater East Asia Ministry Code) present about as much resistance as successive decks of a worm-eaten wooden frigate.

He perfectly fits the profile of a Hut 8 man, who need not know anything except pure math.

For an old spy and codebreaker like myself, nothing in the world happens by coincidence.

She knew the computer's processors auditioned thirty million keys per second – one hundred billion per hour. If TRANSLTR was still counting, that meant the key had to be enormous – over ten billion digits long.

There are only one or two repeats in the whole book. So that got me thinking polyalphabetic substitution.

It uses twenty-six substitution ciphers," he told her. "One for each letter of the alphabet. But the problem is that it requires a keyword to solve.

For the first eight months of the war, as incredible as it sounds, William and Elizebeth, and their team at Riverbank, did all of the codebreaking for every part of the U.S. government: for the State Department, the War Department (army), the navy, and the Department of Justice.

the essence of codebreaking, finding patterns, and because it's such a basic human function, codebreakers have always emerged from unexpected places

But of any science of cryptanalysis, there was nothing. Only cryptography existed. And therefore cryptology, which involves both cryptography and cryptanalysis, had not yet come into being so far

Analyzing the frequency and contacts of letters is the most universal, most basic of cryptanalytic procedures.

Marine Captain Bankson T. Holcomb, Jr., a Japanese-language officer detached from Pearl Harbor's codebreaking unit, picked up a transmission by a Japanese patrol pilot (probably the same one that had been picked up by the carrier's radar). The aircraft had reached the end of its patrol route and the pilot had "nothing to report.
