Exempel på hur man kan använda DECRYPTION i en mening

• The code talkers improved the speed of encryption and decryption of communications in front line operations during World War II and are credited with some decisive victories.
• Symmetric cryptography refers to the practice of the same key being used for both encryption and decryption.
• Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext.
• 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.
• Merkle–Hellman is a public key cryptosystem, meaning that two keys are used, a public key for encryption and a private key for decryption.
• With the advent of computing, the term plaintext expanded beyond human-readable documents to mean any data, including binary files, in a form that can be viewed or used without requiring a key or other decryption device.
• After the interception and decryption of Italian signals by the Government Code and Cypher School (GC&CS) at Bletchley Park (the decrypted intelligence codenamed Ultra), ships of the Royal Navy and Royal Australian Navy, under the command of Royal Navy Admiral Sir Andrew Cunningham, intercepted and sank or severely damaged several ships of the Italian Regia Marina under Squadron-Vice-Admiral Angelo Iachino.
• The decryption was possible after the failure of the Niedermayer-Hentig Expedition to Afghanistan, when Wilhelm Wassmuss abandoned his codebook, which the Allies later recovered, and allowed the British to decrypt the Zimmermann telegram.
• The result of the decryption is 16 bytes of plaintext, which are together with the 17th unencrypted byte which will be interpreted as four double words in little endian byte order followed by a single byte.
• The MITM is a generic attack which weakens the security benefits of using multiple encryptions by storing intermediate values from the encryptions or decryptions and using those to improve the time required to brute force the decryption keys.
• Enigmail is a data encryption and decryption extension for Mozilla Thunderbird and the Postbox that provides OpenPGP public key e-mail encryption and signing.
• Visual cryptography can be used to protect biometric templates in which decryption does not require any complex computations.
• It has the disadvantage that each output of the Rabin function can be generated by any of four possible inputs; if each output is a ciphertext, extra complexity is required on decryption to identify which of the four possible inputs was the true plaintext.
• The term "crib" originated at Bletchley Park, the British World War II decryption operation, where it was defined as:.
• This crib-based decryption is usually not considered a chosen-plaintext attack, even though plain text effectively chosen by the British was injected into the ciphertext, because the choice was very limited and the cryptanalysts did not care what the crib was so long as they knew it.
• KHAZAD makes heavy use of involutions as subcomponents; this minimises the difference between the algorithms for encryption and decryption.
• Beaumanor became one of the most important of the small number of strategic intercept stations, or "Y stations", intercepting enemy radio transmissions and relaying the information to "Station X", at Bletchley Park, for decryption and analysis.
• The Code Book covers diverse historical topics including the Man in the Iron Mask, Arabic cryptography, Charles Babbage, the mechanisation of cryptography, the Enigma machine, and the decryption of Linear B and other ancient writing systems.
• TrueCrypt supports parallelized encryption for multi-core systems and, under Microsoft Windows, pipelined read/write operations (a form of asynchronous processing) to reduce the performance hit of encryption and decryption.
• It features a security mechanism; games are supplied on a CD, which contains the encrypted game contents, and a security cartridge containing the game BIOS and the SH-2 CPU with integrated decryption logic, with the per-game key stored in battery-backed SRAM.
