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.
Lyndon Johnson and Richard Nixon were guilty of unjustified wiretaps, and President John F. Kennedy conducted dubious wiretaps in the first month of his presidency.
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.
Codebreakers are linguistic alchemists, a mystical tribe attempting to conjure sensible words out of meaningless symbols.
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...
„Kolem roku 1790, když byla ratifikována Listina svobod, mohl soukromě mluvit kdokoliv s kýmkoliv - s jistotou, jakou už dnes nemá nikdo - prostě tak, že popošel po cestě kousek od ostatních a podíval...

In the 1980s it was only government, the military and large businesses that owned computers powerful enough to run RSA. Not surprisingly, RSA Data Security, Inc., the company set up to commercialize R...
The construction of mathematical logic had become the arbiter of truth. This was the Pythagoreans' greatest contribution to civilisation - a way of achieving truth which is beyond the fallibility of h...
Histaiaeus shaved the head of his messenger, wrote the message on his scalp, and then waited for the hair to regrow. This was clearly a period of history that tolerated a certain lack of urgency.
Because a quantum computer deals with 1’s and 0’s that are in a quantum superposition, they are called quantum bits, or qubits (pronounced cubits). The advantage of qubits becomes even clearer when we...
All that was required to measure the planet was a man with a stick and a brain. In other words, couple an intellect with some experimental apparatus and almost anything seems achievable.
A large amount of identically encrypted material provides a cryptanalyst with a correspondingly larger chance of identifying the key.
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...
The Third World War would be the mathematicians’ war, because mathematicians will have control over the next great weapon of war—information. Mathematicians have been responsible for developing the co...
Had the cipher machines been used properly—without repeated message keys, without cillies, without restrictions on plugboard settings and scrambler arrangements, and without stereotypical messages whi...
Destitute.
Rejewski had vastly simplified the task of finding the day key by divorcing the problem of finding the scrambler settings from the problem of finding the plugboard settings. On their own, both of thes...
Previous experience, however, tells us that every so-called unbreakable cipher has, sooner or later, succumbed to cryptanalysis
Maths is one of the purest forms of thought, and to outsiders mathematicians may seem almost other-worldly.
