Authenticated encryption (AE) is a cryptographic construction that simultaneously protects
confidentiality and integrity. A considerable amount of research has been devoted to the …

We propose two systematic methods to describe the differential property of an S-box with
linear inequalities based on logical condition modelling and computational geometry …

Data security, privacy and authenticity are crucial in wireless data transmission. Low power
consumption is the main requirement for any chip design targeting the Internet of Things …

In this paper, we investigate the Mixed-integer Linear Programming (MILP) modelling of the
differential and linear behavior of a wide range of block ciphers. We point out that the …

In this article, we provide new methods to look for lightweight MDS matrices, and in
particular involutory ones. By proving many new properties and equivalence classes for …

AES is probably the most widely studied and used block cipher. Also versions with a
reduced number of rounds are used as a building block in many cryptographic schemes, eg …

Recently a lot of attention is paid to the search for efficiently implementable MDS matrices for
lightweight symmetric primitives. Most previous work concentrated on locally optimizing the …

Cryptography is one of the techniques to secure communication and data transfer over the
network. It performs well on resource-rich devices (PC, servers, smartphones, etc.) …

In this article, we analyze the circulant structure of generalized circulant matrices to reduce
the search space for finding lightweight MDS matrices. We first show that the implementation …

Side-channel attacks and in particular differential power analysis (DPA) attacks pose a
serious threat to cryptographic implementations. One approach to counteract such attacks …
