Preserved Fulltext
In this work, we evaluate the security of SKINNY against differential cryptanalysis in the related-tweakey model. ...
Next, actual differential trails for SKINNY under related-tweakey model are explored and optimal differential trails of SKINNY-64 within certain number of rounds are searched with an indirect searching ...

In April 2018, Beierle et al. launched the 3rd SKINNY cryptanalysis competition, a contest that aimed at motivating the analysis of their recent tweakable block cipher SKINNY. ...
In this paper, we explain how to solve the challenges for 10-round SKINNY-128-128 and for 12-round SKINNY-64-128 in time equivalent to roughly 2 52 simple operations. ...
The definition of the tweakey schedule of SKINNY implies that the round tweakeys of all the even rounds (similarly of all the odd rounds) are related together by linear relations. ...

In this paper, we try to combine the two phases in a uniform automatic model.Concretely, we apply this idea to automate the related-key rectangle attacks on SKINNY and ForkSkinny. ...
Our key-recovery attacks on a few versions of round-reduced SKINNY and ForkSkinny cover 1 to 2 more rounds than the best previous attacks. ...
And Romulus is one of the finalists in the LWC project. So the security analysis of SKINNY is of great importance, which also affects the security evaluation of these candidates. ...
