Wave-Shaped Round Functions and Primitive Groups
Riccardo Aragona, Marco Calderini, Roberto Civino +2
Round functions used as building blocks for iterated block ciphers, both in the case of Substitution-Permutation Networks and Feistel Networks, are often obtained as the compositio…
A note on some algebraic trapdoors for block ciphers
Marco Calderini
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, rec…
On Hidden Sums Compatible with A Given Block Cipher Diffusion Layer
Carlo Brunetta, Marco Calderini, Massimiliano Sala
Sometimes it is possible to embed an algebraic trapdoor into a block cipher. Building on previous research, in this paper we investigate an especially dangerous algebraic structure…
On properties of translation groups in the affine general linear group with applications to cryptography
Marco Calderini, Roberto Civino, Massimiliano Sala
The affine general linear group acting on a vector space over a prime field is a well-understood mathematical object. Its elementary abelian regular subgroups have recently drawn a…
