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

Správné použití kvalitní Å¡ifry je velkou pomocí pro obÄ› komunikující strany, avÅ¡ak nekorektní zacházení se slabou Å¡ifrou m?že vyvolat velmi faleÅ¡ný pocit bezpe?í.

first ever military cryptographic device, the Spartan scytale, dating back to the fifth century B.C. The scytale is a wooden staff around which a strip of leather or parchment is wound

Zimmermann employed a neat trick that used asymmetric RSA encryption in tandem with old-fashioned symmetric encryption.

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 consider more particles.

Lidé zapojení do debaty o Å¡ifrování jsou vesmÄ›s inteligentní, ?estní a jsou pro depozici klí??, ale nikdy nemají více než dvÄ› tyto vlastnosti najednou.

The correct use of a strong cipher is a clear boon to sender and receiver, but the misuse of a weak cipher can generate a very false sense of security.

significance of the key, as opposed to the algorithm, is an enduring principle of cryptography. It was definitively stated in 1883 by the Dutch linguist Auguste Kerckhoffs von Nieuwenhof in his book La Cryptographie militaire: "Kerckhoffs' Principle: The security of a cryptosystem must not depend on keeping secret the crypto-algorithm. The security depends only on keeping secret the key.

One of the features of the Enigma machine was its inability to encipher a letter as itself, which was a consequence of the reflector. The letter a could never be enciphered as A, the letter b could never be enciphered as B, and so on.

It has been said that the First World War was the chemists' war, because mustard gas and chlorine were employed for the first time, and that the Second World War was the physicists' war, because the atom bomb was detonated. Similarly, it has been argued that the Third World War would be the mathematicians' war, because mathematicians will have control over the next great weapon of war—information.

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

250 qubits, it is possible to represent roughly 1075 combinations, which is greater than the number of atoms in the universe. If it were possible to achieve the appropriate superposition with 250 particles, then a quantum computer could perform 1075 simultaneous computations

In June 1991 he took the drastic step of asking a friend to post PGP on a Usenet bulletin board. PGP is just a piece of software, and so from the bulletin board it could be downloaded by anyone for free. PGP was now loose on the Internet.

You can't win because of the guns, said Adam with a sigh. Machine guns, mortars, field guns, howitzers: it doesn't matter how much courage soldiers have, how much will; flesh and blood can't pass through bullets and shells, or at least not in sufficient numbers to have any effect. The guns win in the end and they always will. Not us, not the Germans - the guns.

From a book talk in Palo Alto for The Perfectionists; He pulled out his new iphone and told us that its Apple-designed chipset has 8 billion[!] transistors, and that someone at Intel told him that there are now more transistors in electronics than all the leaves on all the world's trees. Something like 15 quintillion of them!

There are now more transistors at work on this planet (some 15 quintillion, or 15,000,000,000,000,000,000) than there are leaves on all the trees in the world. In 2015, the four major chip-making firms were making 14 trillion transistors every single second.

our brains—if we, that is, for our brains are the permanent essence of us—no longer have need of knowledge, and if we have no need because the computers do it all for us, then what is human intelligence good for? An existential intellectual crisis looms: If machines will acquire all our knowledge for us and do our thinking for us, then what, pray, is the need for us to be?

They might have recognized in their strange companion what some of today's middle-aged recognize in the young electronics visionaries... a man who, though part of their world, still had a view that was somehow larger than theirs, that he had firm sight of a future that he somehow knew was better, as well as being a future that was definably different and, most crucially, utterly unlike the world of the present.

Ça ne rapproche pas, le téléphone, ça confirme les distances.

The telephone- it is not a thing that brings people nearer: it underlines remoteness. You are not together as you are in a conversation, for you do not see one another. You are not alone as you are in front of a piece of paper that allows you to talk inwardly while you are addressing the other- to seek out and find the truth.

Money, mechanization, algebra. The three monsters of contemporary civilization.

Going seventy miles an hour but not going anywhere—not enough imagination to want to go anywhere! Getting their music by turning a dial. Getting their phrases from the comic strips instead of from Shakespeare and the Bible and Veblen and Old Bill Sumner. Pap-fed flabs!

a huddle of robot sheep bleating their terror with mechanical lungs of a hundred horsepower.
