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 information input can affect the resultant difference at the output. In the case of a block … See more The discovery of differential cryptanalysis is generally attributed to Eli Biham and Adi Shamir in the late 1980s, who published a number of attacks against various block ciphers and hash functions, including a theoretical … See more The attack relies primarily on the fact that a given input/output difference pattern only occurs for certain values of inputs. Usually the attack is … See more • Cryptography • Integral cryptanalysis • Linear cryptanalysis • Differential equations of addition See more Differential cryptanalysis is usually a chosen plaintext attack, meaning that the attacker must be able to obtain ciphertexts for some set of plaintexts of their choosing. There are, however, extensions that would allow a known plaintext or even a ciphertext-only attack. … See more • Higher-order differential cryptanalysis • Truncated differential cryptanalysis • Impossible differential cryptanalysis See more • Biham E, Shamir A (January 1991).

WebThe cryptanalysis based on the algorithm of algebraic structures can be categorized as follows: a differential cryptanalysis, a linear cryptanalysis, a differential-linear cryptanalysis, a meet-in-the-middle (MITM) attack, and a related-key attack [ 1, 2 ]. http://www.cs.bc.edu/~straubin/crypto2024/heys.pdf

WebWe introduce a new method for cryptanalysis of DES cipher, which is essentially a known-plaintext attack. As a result, it is possible to break 8-round DES cipher with 22' known-plaintexts and 16-round DES cipher with 2" known-plaintexts, respectively. Moreover, this method is applicable to an only-ciphertext attack in certain situations.
