On the primitivity of Lai-Massey schemes
Riccardo Aragona, Roberto Civino
In symmetric cryptography, the round functions used as building blocks for iterated block ciphers are often obtained as the composition of different layers providing confusion and…
Rigid commutators and a normalizer chain
Riccardo Aragona, Roberto Civino, Norberto Gavioli +1
The novel notion of rigid commutators is introduced to determine the sequence of the logarithms of the indices of a certain normalizer chain in the Sylow 2-subgroup of the symmetri…
A Chain of Normalizers in the Sylow -subgroups of the symmetric group on letters
Riccardo Aragona, Roberto Civino, Norberto Gavioli +1
On the basis of an initial interest in symmetric cryptography, in the present work we study a chain of subgroups. Starting from a Sylow -subgroup of AGL(2,n), each term of the c…
An Authenticated Key Scheme over Elliptic Curves for Topological Networks
Riccardo Aragona, Roberto Civino, Norberto Gavioli +1
Nodes of sensor networks may be resource-constrained devices, often having a limited lifetime, making sensor networks remarkably dynamic environments. Managing a cryptographic prot…
