Tuple Cryptanalysis: Slicing and Fusing Multisets
Résumé
In this paper, we revisit the notions of Square, saturation, integrals, multisets, bit patterns and tuples, and propose a new Slice & Fuse paradigm to better exploit multiset type properties of block ciphers, as well as relations between multisets and constituent bitslice tuples. With this refined analysis, we are able to improve the best bounds proposed in such contexts against the following block ciphers: Threefish, Prince, Present and Rectangle.
