• 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

• Impossible differential cryptanalysis — In cryptography, impossible differential cryptanalysis is a form of differential cryptanalysis for block ciphers. While ordinary differential cryptanalysis tracks differences that propagate through the cipher with greater than expected… …   Wikipedia

• Truncated differential cryptanalysis — In cryptography, truncated differential cryptanalysis is a generalization of differential cryptanalysis, an attack against block ciphers. Lars Knudsen developed the technique in 1994. Whereas ordinary differential cryptanalysis analyzes the full… …   Wikipedia

• Higher order differential cryptanalysis — In cryptography, higher order differential cryptanalysis is a generalization of differential cryptanalysis, an attack against block ciphers. Developed in 1994 by Lars Knudsen, the technique has been applied to a number of ciphers. Whereas… …   Wikipedia

• Cryptanalysis — Close up of the rotors in a Fialka cipher machine Cryptanalysis (from the Greek kryptós, hidden , and analýein, to loosen or to untie ) is the study of methods for obtaining the meaning of encrypted information, without access to the secret… …   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

• 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

• Linear cryptanalysis — In cryptography, linear cryptanalysis is a general form of cryptanalysis based on finding affine approximations to the action of a cipher. Attacks have been developed for block ciphers and stream ciphers. Linear cryptanalysis is one of the two… …   Wikipedia

• Mod n cryptanalysis — In cryptography, mod n cryptanalysis is an attack applicable to block and stream ciphers. It is a form of partitioning cryptanalysis that exploits unevenness in how the cipher operates over equivalence classes (congruence classes) modulo n. The… …   Wikipedia
