The boomerang attack is a cryptanalysis technique that combines two short differentials
instead of using a single long differential. It has been applied to many primitives, and results …

In this paper, we propose Tweak-aNd-Tweak (TNT TNT for short) mode, which builds a
tweakable block cipher from three independent block ciphers. TNT TNT handles the tweak …

A new fundamental 4-round property of AES, called the zero-difference property, was
introduced by R {\o} njom, Bardeh and Helleseth at Asiacrypt 2017. Our work characterizes it …

This paper proposes Pholkos, a family of heavyweight tweakable block ciphers with state
and key sizes of≥ 256 and tweaks of either 128 or 256 bits. When encrypting large chunks …

Distinguishers on round-reduced AES have attracted considerable attention in the recent
years. While the number of rounds covered in key-recovery attacks did not increase …

In this paper we propose a new family of highly efficient and quantum secure AES-based
block cipher dubbed Ghidle, which supports a key size of 256 bits and a state size of 256 or …

In this work, we propose a construction of 2-round tweakable substitutionpermutation
networks using a single secret S-box. This construction is based on non-linear permutation …

Abstract 3D is an Advanced Encryption Standard (AES)-like cipher employed 3D structure
proposed in 2008. The main innovation of 3D is the multi-dimensional state, generalizing the …

Symmetric key cryptography refers to the encryption methods in which the same key is used
by both the sender and the receiver. Cryptanalysis is a process of finding vulnerabilities in …

Modern cryptography has become an often ubiquitous but essential part of our daily lives.
Protocols for secure authentication and encryption protect our communication with various …
