Exempel på hur man kan använda CRYPTANALYSIS i en mening

• Blowfish provides a good encryption rate in software, and no effective cryptanalysis of it has been found to date for smaller files.
• Colossus was a set of computers developed by British codebreakers in the years 1943–1945 to help in the cryptanalysis of the Lorenz cipher.
• Differential cryptanalysis is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions.
• Decipherment overlaps with another technical field known as cryptanalysis, a field that aims to decipher writings used in secret communication, known as ciphertext.
• The origins of machine translation can be traced back to the work of Al-Kindi, a ninth-century Arabic cryptographer who developed techniques for systemic language translation, including cryptanalysis, frequency analysis, and probability and statistics, which are used in modern machine translation.
• As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis (to decipher the messages).
• During the Second World War, he made a brilliant and fundamental advance in cryptanalysis of the Lorenz cipher, a major Nazi German cipher system which was used for top-secret communications within the Wehrmacht High Command.
• In cryptanalysis and computer security, a dictionary attack is an attack using a restricted subset of a keyspace to defeat a cipher or authentication mechanism by trying to determine its decryption key or passphrase, sometimes trying thousands or millions of likely possibilities often obtained from lists of past security breaches.
• He is a co-inventor of the Rivest–Shamir–Adleman (RSA) algorithm (along with Ron Rivest and Len Adleman), a co-inventor of the Feige–Fiat–Shamir identification scheme (along with Uriel Feige and Amos Fiat), one of the inventors of differential cryptanalysis and has made numerous contributions to the fields of cryptography and computer science.
• In cryptography, linear cryptanalysis is a general form of cryptanalysis based on finding affine approximations to the action of a cipher.
• A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts.
• Means of information gathering are both overt and covert and may include espionage, communication interception, cryptanalysis, cooperation with other institutions, and evaluation of public sources.
• A chosen-ciphertext attack (CCA) is an attack model for cryptanalysis where the cryptanalyst can gather information by obtaining the decryptions of chosen ciphertexts.
• Elizebeth Friedman's cryptanalysis unit at US Coast Guard Headquarters in Washington examined the letter and broke the code, concluding that the "dolls" were actually three warships and that the "doll hospital" was a West Coast-based shipyard where repairs were made, while the "fishing nets" and "balloons" disclosed information about coastal defenses and other critical information on the West Coast.
• When DES was first published in 1977, the design criteria of its S-boxes were kept secret to avoid compromising the technique of differential cryptanalysis (which was not yet publicly known).
• 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.
• 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.
• This maximizes parallelism but also allows use of the extensive cryptanalysis work performed on DES.
• 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.
• 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.
