Cryptographic network protocols play a crucial role in enabling secure data exchange over
insecure media in modern network environments. However, even minor vulnerabilities can …

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 …

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 …

We show that many symmetric cryptography primitives would not be less safe with
significantly fewer rounds. To support this claim, we review the cryptanalysis progress in the …

In recent years, several MILP models were introduced to search automatically for
boomerang distinguishers and boomerang attacks on block ciphers. However, they can only …

We present Orthros, a 128-bit block pseudorandom function. It is designed with primary
focus on latency of fully unrolled circuits. For this purpose, we adopt a parallel structure …

This work investigates a generic way of combining two very effective and well-studied
cryptanalytic tools, proposed almost 18 years apart, namely the boomerang attack …

Camellia is an encryption algorithm implemented in many Internet of Things (IoT) devices.
However, intruders attack the Camellia cipher using Substitution Box (S-Box) distinguishers …

Boomerang attacks are extensions of differential attacks that make it possible to combine
two unrelated differential properties of the first and second part of a cryptosystem with …

The double boomerang connectivity table (DBCT) is a new table proposed recently to
capture the behavior of two consecutive S-boxes in boomerang attacks. In this paper, we …
