On the primitivity of PRESENT and other lightweight ciphers
Riccardo Aragona, Marco Calderini, Antonio Tortora +1
We provide two sufficient conditions to guarantee that the round functions of a translation based cipher generate a primitive group. Furthermore, under the same hypotheses, and ass…
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…
