In this paper we consider various methods and techniques to find the smallest circuit realizing a given linear transformation on nn input signals and mm output signals, with a constraint of a maximum ...
In this work, we discuss two notions of differential equivalence on Sboxes. First, we introduce the notion of DDT-equivalence which applies to vectorial Boolean functions that share the same differenc...
Side-channel attacks exploit physical characteristics of implementations of cryptographic algorithms in order to extract sensitive information such as the secret key. These physical attacks are among ...
Block ciphers are arguably the most important cryptographic primitive in practice. While their security against mathematical attacks is rather well understood, physical threats such as side-channel an...
We describe a new technique for improving the efficiency of the masking countermeasure against side-channel attacks. Our technique is based on using common shares between secret variables, in order ...
This paper investigates the effect of affine transformations of the Sbox on the maximal expected differential probability MEDP and linear potential MELP over two rounds of a substitution-permutation n...
Linear and differential cryptanalysis and their generalizations are the most important tools in statistical analysis of symmetric ciphers. These attacks make use of linear and differential propertie...
