Some group-theoretical results on Feistel Networks in a long-key scenario
Riccardo Aragona, Marco Calderini, Roberto Civino
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-li…
Entropy and Compression: A simple proof of an inequality of Khinchin-Ornstein-Shields
Riccardo Aragona, Francesca Marzi, Filippo Mignosi +1
This paper concerns the folklore statement that ``entropy is a lower bound for compression''. More precisely we derive from the entropy theorem a simple proof of a pointwise inequa…
Normal form in Hecke-Kiselman monoids associated with simple oriented graphs
Riccardo Aragona, Alessandro D'Andrea
We generalize Kudryavtseva and Mazorchuk's concept of canonical form of elements in Kiselman's semigroups to the setting of a Hecke-Kiselman monoid associated with…
