Five-weight codes from three-valued correlation of M-sequences
(Journal article; Peer reviewed, 2023)In this paper, for each of six families of three-valued m-sequence correlation, we construct an infinite family of five-weight codes from trace codes over the ring R = F2 + uF2, where u2 = 0. The trace codes have the ... -
A note on some algebraic trapdoors for block ciphers
(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 ... -
Some group-theoretical results on Feistel Networks in a long-key scenario
(Journal article; Peer reviewed, 2020)The study of the trapdoors that can be hidden in a block cipher is and has always been a high-interest topic in symmetric cryptography. In this paper we focus on Feistel-network-like ciphers in a classical long-key scenario ... -
Wave-shaped round functions and primitive groups
(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 ...
