• A note on some algebraic trapdoors for block ciphers 

      Calderini, Marco (Peer reviewed; Journal article, 2018)
      We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al. (2016) and it ...
    • Wave-shaped round functions and primitive groups 

      Aragona, Riccardo; Calderini, Marco; Civino, Roberto; Sala, Massimiliano; Zappatore, Ilaria (Peer reviewed; Journal article, 2019)
      Round functions used as building blocks for iterated block ciphers, both in the case of Substitution-Permutation Networks (SPN) and Feistel Networks (FN), are often obtained as the composition of different layers. The ...
