Differential cryptanalysis — is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions. In the broadest sense, it is the study of how differences in an input can affect the resultant difference at… … Wikipedia
Differential space–time code — Differential space–time codes[1][2] are ways of transmitting data in wireless communications. They are forms of space–time code that do not need to know the channel impairments at the receiver in order to be able to decode the signal. They are… … Wikipedia
Differential thermal analysis — Acronym DTA Classification Thermal analysis Other techniques Related Dynamic mechanical analysis Thermomechanical analysis Thermogravimetric analysis Differential thermal analysis Dielectric thermal analysis Differential thermal an … Wikipedia
Differential fault analysis — is a type of side channel attack in the field of cryptography, specifically cryptanalysis. The principle is to induce faults unexpected environmental conditions into cryptographic implementations, to reveal their internal states. For example, a… … Wikipedia
Block cipher — In cryptography, a block cipher is a symmetric key cipher operating on fixed length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take (for example) a 128 bit block of plaintext as… … Wikipedia
Differential-linear attack — Introduced by Martin Hellman and Susan K. Langford in 1994, the differential linear attack is a mix of both linear cryptanalysis and differential cryptanalysis. The attack utilises a differential characteristic over part of the cipher with a… … Wikipedia
Differential equations of addition — In cryptography, differential equations of addition (DEA) are one of the most basic equations related to differential cryptanalysis that mix additions over two different groups (e.g. addition modulo 232 and addition over GF(2)) and where input… … Wikipedia
Block cipher modes of operation — This article is about cryptography. For method of operating , see modus operandi. In cryptography, modes of operation is the procedure of enabling the repeated and secure use of a block cipher under a single key.[1][2] A block cipher by itself… … Wikipedia
Differential pulley — Figure 1 Differential pulley. A differential pulley, sometimes called a chain hoist, or sometimes colloquially called a chain fall, is used to manually lift very heavy objects like car engines. It is operated by pulling upon the slack… … Wikipedia
