Traditionally, countermeasures against physical attacks are integrated into the
implementation of cryptographic primitives after the algorithms have been designed for …

A boomerang attack is a cryptanalysis framework that regards a block cipher E as the
composition of two sub-ciphers E_1 ∘ E_0 E 1∘ E 0 and builds a particular characteristic for …

Abstract The National Institute of Standards and Technology (NIST) initiated a public
standardization process to select one or more Authenticated Encryption with Associated …

Abstract Impossible differential (ID), zero-correlation (ZC), and integral attacks are a family of
important attacks on block ciphers. For example, the impossible differential attack was the …

Resistance against differential cryptanalysis is an important design criteria for any modern
block cipher and most designs rely on finding some upper bound on probability of single …

When generating quartets for the rectangle attacks on ciphers with linear key-schedule, we
find the right quartets which may suggest key candidates have to satisfy some nonlinear …

Highly efficient encryption and authentication of short messages is an essential requirement
for enabling security in constrained scenarios such as the CAN FD in automotive systems …

The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard
the target cipher E as a composition of two sub-ciphers, ie, E= E1∘ E0, to construct a …

Search for different types of distinguishers are common tasks in symmetric-key cryptanalysis.
In this work, we employ the constraint programming (CP) technique to tackle such problems …

In this paper we describe a new tool to search for boomerang distinguishers. One limitation
of the MILP model of Liu et al. is that it handles only one round for the middle part while …
