Informatica Differential attacks using alternative operations Roberto Civino 26-02-2020 - 15:00 Largo San Leonardo Murialdo,1 - Pal.C - Aula 311
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 |
