Esempi di utilizzo di CIPHERS in una frase

• Differential cryptanalysis is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions.
• Transposition ciphers reorder units of plaintext (typically characters or groups of characters) according to a regular system to produce a ciphertext which is a permutation of the plaintext.
• Modern ciphers aim to provide semantic security, also known as ciphertext indistinguishability under chosen-plaintext attack, and they are therefore, by design, generally immune to chosen-plaintext attacks if correctly implemented.
• The ciphers used in cryptograms were created not for entertainment purposes, but for real encryption of military or personal secrets.
• The work of Al-Qalqashandi (1355–1418), based on the earlier work of Ibn al-Durayhim (1312–1359), contained the first published discussion of the substitution and transposition of ciphers, as well as the first description of a polyalphabetic cipher, in which each plaintext letter is assigned more than one substitute.
• The tabula recta is often referred to in discussing pre-computer ciphers, including the Vigenère cipher and Blaise de Vigenère's less well-known autokey cipher.
• In some ciphers, such properties of the natural language plaintext are preserved in the ciphertext, and these patterns have the potential to be exploited in a ciphertext-only attack.
• The Playfair cipher is thus significantly harder to break since the frequency analysis used for simple substitution ciphers does not work with it.
• Building on the work of al-Khalil (717–786), Al-Kindi's book entitled Manuscript on Deciphering Cryptographic Messages gave rise to the birth of cryptanalysis, was the earliest known use of statistical inference, and introduced several new methods of breaking ciphers, notably frequency analysis.
• Fish (sometimes capitalised as FISH) was the UK's GC&CS Bletchley Park codename for any of several German teleprinter stream ciphers used during World War II.
• Although certainly not as complex or secure as modern computer operated stream ciphers or block ciphers, in practice messages protected by it resisted all attempts at cryptanalysis by at least the NSA from its discovery in 1953 until Häyhänen's defection in 1957.
• The British cryptanalysts of Bletchley Park codenamed the German teleprinter ciphers Fish, with individual cipher-systems being given further codenames: just as the T52 was called Sturgeon, the Lorenz machine was codenamed Tunny.
• Decoders, whether badges or rings, are an entertaining way for children to tap into a common fascination with encryption, ciphers, and secret codes, and are used to send hidden messages back and forth to one another.
• Py (with Jennifer Seberry), one of a family of fast stream ciphers (see article for more detail on their cryptanalytic status).
• Systolic arrays were first used in Colossus, which was an early computer used to break German Lorenz ciphers during World War II.
• In cryptography, a Feistel cipher (also known as Luby–Rackoff block cipher) is a symmetric structure used in the construction of block ciphers, named after the German-born physicist and cryptographer Horst Feistel, who did pioneering research while working for IBM; it is also commonly known as a Feistel network.
• In cryptography, Lucifer was the name given to several of the earliest civilian block ciphers, developed by Horst Feistel and his colleagues at IBM.
• 850 – cryptanalysis and frequency analysis algorithms developed by Al-Kindi (Alkindus) in A Manuscript on Deciphering Cryptographic Messages, which contains algorithms on breaking encryptions and ciphers.
• The MITM attack attempts to find the keys by using both the range (ciphertext) and domain (plaintext) of the composition of several functions (or block ciphers) such that the forward mapping through the first functions is the same as the backward mapping (inverse image) through the last functions, quite literally meeting in the middle of the composed function.
• Rijmen is also the co-designer of the WHIRLPOOL cryptographic hash function, and the block ciphers Anubis, KHAZAD, Square, NOEKEON and SHARK.
• German military officer Friedrich Kasiski publishes Die Geheimschriften und die Dechiffrir-Kunst ("Secret writing and the Art of Deciphering"), the first published general method for cryptanalysis of polyalphabetic ciphers, especially the Vigenère cipher.
• The Beale ciphers are a set of three ciphertexts, one of which allegedly states the location of a buried treasure of gold, silver and jewels estimated to be worth over 43 million US dollars  Comprising three ciphertexts, the first (unsolved) text describes the location, the second (solved) ciphertext accounts the content of the treasure, and the third (unsolved) lists the names of the treasure's owners and their next of kin.
• Since the affine cipher is still a monoalphabetic substitution cipher, it inherits the weaknesses of that class of ciphers.
• It details the basics of symmetric key, and asymmetric key ciphers, MACs, SSL, secure mail and IPsec.
• The extent of sophistication posed little problem for Friedman; she mounted successful attacks against simple substitution and transposition ciphers, as well as the more complex ciphers which eventually came into use.
