A new multivariate primitive from CCZ equivalence
Marco Calderini, Alessio Caminata, Irene Villa
Multivariate Cryptography is one of the candidates for Post-quantum Cryptography. Multivariate schemes are usually constructed by applying two secret affine invertible transformati…
On Dillon's property of -functions
Matteo Abbondati, Marco Calderini, Irene Villa
Dillon observed that an APN function over with greater than must satisfy the condition $\{F(x) + F(y) + F(z) + F(x + y + z) \,:\, x,y,z \in\mathbb{F}…
Two new families of bivariate APN functions
Marco Calderini, Kangquan Li, Irene Villa
In this work, we present two new families of quadratic APN functions. The first one (F1) is constructed via biprojective polynomials. This family includes one of the two APN famili…
A survey on Functional Encryption
Carla Mascia, Massimiliano Sala, Irene Villa
Functional Encryption (FE) expands traditional public-key encryption in two different ways: it supports fine-grained access control and allows learning a function of the encrypted…
On some cryptographic properties of Boolean functions and their second-order derivatives
Augustine Musukwa, Massimiliano Sala, Marco Zaninelli
In this paper some cryptographic properties of Boolean functions, including weight, balancedness and nonlinearity, are studied, particularly focusing on splitting functions and cub…
On Some Properties of Quadratic APN Functions of a Special Form
Irene Villa
In a recent paper, it is shown that functions of the form , where and are linear, are a good source for construction of new infinite families of APN…
A note on APN permutations in even dimension
Marco Calderini, Massimilano Sala, Irene Villa
APN permutations in even dimension are vectorial Boolean functions that play a special role in the design of block ciphers. We study their properties, providing some general result…
