Differential attacks using alternative operations
Mercoledì 26 febbraio alle ore 15:00, presso l'aula 311 di Largo San Leonardo Murialdo1, il prof. Roberto Civino, dell'Università degli Studi dell'Aquila, presenterà il seminario di crittografia dal titolo "Differential attacks using alternative operations".

Abstract:
Block ciphers and their security are the main subjects of this seminar, where it is described the impact of differential cryptanalysis, a powerful statistical attack against block ciphers, when operations different from the one used to perform the key addition are considered on the message space. It is proven that when an alternative difference operation is carefully designed, a cipher that is proved secure against classical differential cryptanalysis can instead be attacked using this alternative difference
