Scientific proof is inevitably fickle and shoddy. On the other hand mathematical proof is absolute and devoid of doubt.
Syllabic scripts occupy the middle ground, with between 50 and 100 syllabic characters. Beyond these two facts, Linear B was an unfathomable mystery.
They called the Navajo language a weird succession of guttural, nasal, tongue-twisting sounds … we couldn’t even transcribe it, much less crack it.
Half of them at random will be blocked, and half will pass through, and those that do pass through will be reoriented with a vertical polarization.
As a society, we rightly adore our great musicians and novelists, yet we seldom hear any mention of the humble mathematician. It is clear that mathematics is not considered part of our culture. Instea...
Enigma decipherments gave the locations of numerous U-boats, but it would have been unwise to attack every single one of them, because a sudden, unexplained increase in successful British attacks woul...
Enigma was considered invulnerable, until the Poles revealed its weaknesses.
I recall thinking that this paper would be the least interesting paper that I will ever be on. Adleman could not have been more wrong. The system, dubbed RSA (Rivest, Shamir, Adleman) as opposed to AR...
Não existe utilidade prática em saber que π é irracional, mas, se podemos saber, então certamente seria intolerável não saber.
Quantum cryptography would mark the end of the battle between codemakers and codebreakers, the codemakers emerging victorious, because quantum cryptography is a truly unbreakable system of encryption.
Rejewski had no idea of the day key, and he had no idea which message keys were being chosen, but he did know that they resulted in this table of relationships. Had
The letters a and l are the most common in Arabic, partly because of the definite article al-, whereas the letter j appears only a tenth as frequently.
Impenetrability of the Navajo code was all down to the fact that Navajo belongs to the Na-Dene family of languages, which has no link with any Asian or European language.
The Arab scholars were also capable of destroying ciphers. They in fact invented cryptanalysis, the science of unscrambling a message without knowledge of the key.
The numerous losses were either the result of natural misfortune or caused by a British spy who had infiltrated the German navy. The breaking of Enigma was considered impossible and inconceivable.
A large amount of identically encrypted material provides a cryptanalyst with a correspondingly larger chance of identifying the key.
At the same time as acquiring knowledge, the Islamic civilization was able to disperse it, because it had procured the art of paper-making from the Chinese. The manufacture of paper gave rise to the p...
Codebreakers are linguistic alchemists, a mystical tribe attempting to conjure sensible words out of meaningless symbols.
Figure 6 The science of secret writing and its main branches.
In the 1970s, banks attempted to distribute keys by employing special dispatch riders who had been vetted and who were among the company’s most trusted employees.
