Cryptography is the practice and study of hiding information. In modern times cryptography is considered a branch of both mathematics and computer science and is affiliated closely with information theory, computer security and engineering.... , truncated differential cryptanalysis is a generalization of differential cryptanalysis
Differential cryptanalysis
Differential cryptanalysis is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions.... , an attack against block cipher
Block cipher
In cryptography, a block cipher is a symmetric key algorithm cipher which operates on fixed-length groups of bits, termed blocks, with an unvarying transformation.... s. Lars Knudsen
Lars Knudsen
Lars Ramkilde Knudsen is a Denmark researcher in cryptography, particularly interested in the design and cryptanalysis of block ciphers, cryptographic hash function and message authentication codes .... developed the technique in 1994. Whereas ordinary differential cryptanalysis analyzes the full difference between two texts, the truncated variant considers differences that are only partially determined. It has been applied to SAFER
SAFER
In cryptography, SAFER is the name of a family of block ciphers designed primarily by James Massey on behalf of Cylink Corporation. The early SAFER K and SAFER SK designs share the same encryption function, but differ in the number of rounds and the key schedule.... , IDEA
International Data Encryption Algorithm
In cryptography, the International Data Encryption Algorithm is a block cipher designed by Xuejia Lai and James Massey of ETH Zurich and was first described in 1991.... , Skipjack
Skipjack (cipher)
In cryptography, Skipjack is a block cipher — an algorithm for encryption — developed by the United States National Security Agency .... , E2
E2 (cipher)
In cryptography, E2 is a block cipher which was created in 1998 by Nippon Telegraph and Telephone and submitted to the AES competition.Like other AES candidates, E2 operates on blocks of 128 bits, using a key of 128, 192, or 256 bits.... , Twofish
Twofish
In cryptography, Twofish is a Symmetric-key algorithm block cipher with a block size of 128 bits and key sizes up to 256 bits. It was one of the five finalists of the Advanced Encryption Standard process, but was not selected for standardisation.... , Camellia
Camellia (cipher)
In cryptography, Camellia is a block cipher that has been evaluated favorably by several organisations, including the European Union's NESSIE project , and the Japanese CRYPTREC project .... , CRYPTON
CRYPTON
In cryptography, CRYPTON is a block cipher submitted as a candidate for the Advanced Encryption Standard . It is very efficient in hardware implementations and was designed by Chae Hoon Lim of Future Systems Inc.... , and even the stream cipher
Stream cipher
In cryptography, a stream cipher is a symmetric key algorithm cipher where plaintext bits are combined with a pseudorandom cipher bit stream , typically by an exclusive-or operation.... Salsa20
Salsa20
File:Salsa round function.svgSalsa20 is a stream cipher submitted to eSTREAM by Daniel Bernstein. It is built on a pseudorandom function based on 32-bit addition, bitwise addition and rotation operations, which maps a 256-bit key size, a 64-bit cryptographic nonce, and a 64-bit stream position to a 512-bit output .... .
