Pythagoras, the teacher, paid his student three oboli for each lesson he attended
The first known European book to describe the use of cryptography was written in the thirteenth century by the English Franciscan monk and polymath Roger Bacon. Epistle on the Secret Works of Art and...
Turing knew of Babbage’s work, and the universal Turing machine can be seen as a reincarnation of Difference Engine No. 2. In fact, Turing had gone much further, and provided computing with a solid th...
Vigenère’s work culminated in his Traicté des Chiffres (A Treatise on Secret Writing), published in 1586. Ironically, this was the same year that Thomas Phelippes was breaking the cipher of Mary Queen...
The greatest tribute to the work of the Navajo is the simple fact that their code is one of very few throughout history that was never broken.
War, instead of finishing in 1945, would have ended in 1948 had the Government Code and Cypher School not been able to read the Enigma cyphers and produce the Ultra intelligence. During this period of...
Al-Kindi's technique, known as frequency analysis, shows that it is unnecessary to check each of the billions of potential keys. Instead, it is possible to reveal the contents of a scrambled message s...
Even after Pythagoras’s death a member of the Brotherhood was drowned for breaking his oath—he publicly announced the discovery of a new regular solid, the dodecahedron, constructed from twelve regula...
Jestliže někdy platí, že nutnost je matkou invence, pak je rovněž možné, že ohrožení je matkou kryptoanalýzy.
On a fatal day, in the holy season of Lent, Hypatia was torn from her chariot, stripped naked, dragged to the church, and inhumanely butchered by the hands of Peter the Reader and a troop of savage an...
Stát, který věří, že není správné číst cizí dopisy, časem začne věřit i tomu, že jeho korespondenci také nikdo nečte...
It can be mathematically proved that it is impossible for a cryptanalyst to crack a message encrypted with a onetime pad cipher. In other words, the onetime pad cipher is not merely believed to be unb...
Many shipwrecks and engineering disasters were blamed on faulty tables. These mathematical tables were calculated by hand, and the mistakes were simply the result of human error. This caused Babbage t...
A Navajo message could never be faked and could always be trusted.
Alan Turing was another cryptanalyst who did not live long enough to receive any public recognition. Instead of being acclaimed a hero, he was persecuted for his homosexuality. In 1952, while reportin...
Although this may seem a paradox, all exact science is dominated by the idea of approximation.
For decades, ENIAC, not Colossus, was considered the mother of all computers.
He took the messages to a local brewer, who wrapped them in a leather packet, which was then hidden inside a hollow bung used to seal a barrel of beer. The brewer would deliver the barrel to Chartley...
In fact, Britain had captured thousands of Enigma machines, and distributed them among its former colonies, who believed that the cipher was as secure as it had seemed to the Germans. The British did...
It is the same with life. Some are influenced by the love of wealth while others are blindly led on by the mad fever for power and domination, but the finest type of man gives himself up to discoverin...
