• 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

• 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

• Linear (disambiguation) — Definition: The word linear comes from the Latin word linearis, which means created by lines. Usage in mathematics: * Linear, a property; * Linear code; * Linear equation; * Linear function; * Linear programming, a type of optimization problem; * …   Wikipedia

• Cryptanalysis of TIA's Common Cryptographic Algorithms — In 1992, the TR 45 working group within the Telecommunications Industry Association (TIA) developed a standard for integration of cryptographic technology into tomorrow s digital cellular systems [TIA92] , which has been updated at least once… …   Wikipedia

• Linear feedback shift register — [ xor gate provides feedback to the register that shifts bits from left to right. The maximal sequence consists of every possible state except the 0000 state.] A linear feedback shift register (LFSR) is a shift register whose input bit is a… …   Wikipedia

• 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

• Partitioning cryptanalysis — In cryptography, partitioning cryptanalysis is a form of cryptanalysis for block ciphers. Developed by Carlo Harpes in 1995, the attack is a generalization of linear cryptanalysis. Harpes originally replaced the bit sums (affine transformations)… …   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

• 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

• 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

• Decision Linear assumption — The Decision Linear (DLIN) assumption is a mathematical assumption used in elliptic curve cryptography. In particular, the DLIN assumption is useful in settings where the decisional Diffie–Hellman assumption does not hold (as is often the case in …   Wikipedia
