What is Truncated differential cryptanalysis?
In [[cryptography]], '''truncated differential cryptanalysis''' is a generalization of [[differential cryptanalysis]], an [[attack model]] against [[block cipher]]s. In 1994 [[Lars Knudsen]] [[design]]ed the [[technique]], during this period ordinary [[differential cryptanalysis]] [[Analysis|analyzes]] the full difference between two texts, the truncated version considers differences that are only determined to some extent. It has been applied to [[SAFER]], [[International Data Encryption Algorithm|IDEA]], [[Skipjack (cipher)|Skipjack]], [[E2 (cipher)|E2]], [[Twofish]], [[Camellia (cipher)|Camellia]], [[CRYPTON]], and the [[stream cipher]] [[Salsa20]] as well. ==References== * {{ cite conference | author = [[Lars Knudsen]] | title = Truncated and Higher Order Differentials | book-title = 2nd International Workshop on [[Fast Software Encryption]] (FSE 1994) | pages = 196–211 | publisher = [[Springer-Verlag]] | date = 1994 | location = [[Leuven]] | url = http://citeseer.ist.psu.edu/knudsen95truncated.html | format = [[PDF]]/[[PostScript]] | accessdate = 2007-02-14 }} * {{ cite conference | author = Lars Knudsen, [[Tom Berson|Thomas Berson]] | title = Truncated Differentials of SAFER | book-title = 3rd International Workshop on Fast Software Encryption (FSE 1996) | pages = 15–26 | publisher = Springer-Verlag | date = 1996 | location = [[Cambridge]] | url = http://citeseer.ist.psu.edu/knudsen96truncated.html | format = PDF/PostScript | accessdate = 2007-02-27 }} * {{cite conference | author = [[Johan Borst]], Lars R.
