Truncated differential cryptanalysis
In cryptography, truncated differential cryptanalysis is a generalization of differential cryptanalysis, an attack model against block ciphers. In 1994 Lars Knudsen designed the technique, during this period ordinary differential cryptanalysis 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, IDEA, Skipjack, E2, Twofish, Camellia, CRYPTON, and the stream cipher Salsa20 as well.
