Boomerang connectivity table: a new cryptanalysis tool
A boomerang attack is a cryptanalysis framework that regards a block cipher E as the
composition of two sub-ciphers E_1 ∘ E_0 E 1∘ E 0 and builds a particular characteristic for …

Differential cryptanalysis in the fixed-key model
A systematic approach to the fixed-key analysis of differential probabilities is proposed. It is
based on the propagation of 'quasidifferential trails', which keep track of probabilistic linear …
