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…
Several Proofs of Security for a Tokenization Algorithm
Riccardo Longo, Massimiliano Sala, Riccardo Aragona
In this paper we propose a tokenization algorithm of Reversible Hybrid type, as defined in PCI DSS guidelines for designing a tokenization solution, based on a block cipher with a…
A proof of security for a key-policy RS-ABE scheme
Federico Giacon, Riccardo Aragona, Massimiliano Sala
A revocable-storage attribute-based encryption (RS-ABE) scheme is an encryption scheme which extends attribute-based encryption by intro- ducing user revocation. A key-policy RS-AB…
On weak differential uniformity of vectorial Boolean functions as a cryptographic criterion
R. Aragona, M. Calderini, D. Maccauro +1
We study the relation among some security parameters for vectorial Boolean functions which prevent attacks on the related block cipher. We focus our study on a recently-introduced…
