Optimal s-boxes against alternative operations and linear propagation
Marco Calderini, Roberto Civino, Riccardo Invernizzi
Civino et al. (2019) have shown how some diffusion layers can expose a Substitution-Permutation Network to vulnerability from differential cryptanalysis when employing alternative…
Differential experiments using parallel alternative operations
Marco Calderini, Roberto Civino, Riccardo Invernizzi
The use of alternative operations in differential cryptanalysis, or alternative notions of differentials, are lately receiving increasing attention. Recently, Civino et al. managed…
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…
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…
On the Equivalence of Two Security Notions for Hierarchical Key Assignment Schemes in the Unconditional Setting
Massimo Cafaro, Roberto Civino, Barbara Masucci
The access control problem in a hierarchy can be solved by using a hierarchical key assignment scheme, where each class is assigned an encryption key and some private information.…
