Wave-Shaped Round Functions and Primitive Groups [PDF]
, 2018 Round functions used as building blocks for iterated block ciphers, both in the case of Substitution-Permutation Networks and Feistel Networks, are often obtained as the composition of different layers which provide confusion and diffusion, and key ...

Towards Low Energy Stream Ciphers
IACR Transactions on Symmetric Cryptology, 2018 Energy optimization is an important design aspect of lightweight cryptography. Since low energy ciphers drain less battery, they are invaluable components of devices that operate on a tight energy budget such as handheld devices or RFID tags.

Simplified Modeling of MITM Attacks for Block Ciphers: New (Quantum) Attacks
IACR Transactions on Symmetric Cryptology, 2023 The meet-in-the-middle (MITM) technique has led to many key-recovery attacks on block ciphers and preimage attacks on hash functions. Nowadays, cryptographers use automatic tools that reduce the search of MITM attacks to an optimization problem.

A Security Analysis of IoT Encryption: Side-channel Cube Attack on Simeck32/64 [PDF]
, 2018 Simeck, a lightweight block cipher has been proposed to be one of the encryption that can be employed in the Internet of Things (IoT) applications. Therefore, this paper presents the security of the Simeck32/64 block cipher against side-channel cube ...

Algebraic Techniques in Differential Cryptanalysis [PDF]
, 2008 . In this paper we propose a new cryptanalytic method against block ciphers, which combines both algebraic and statistical techniques. More specifically, we show how to use algebraic relations arising from differential characteristics to speed up and ...

Hybrid Code Lifting on Space-Hard Block Ciphers
IACR Transactions on Symmetric Cryptology, 2022 There is a high demand for whitebox cryptography from the practical use of encryption in untrusted environments. It has been actively discussed for two decades since Chow et al. presented the whitebox implementation of DES and AES. The goal is to resist

Automatic method for searching integral distinguishers of ARX block ciphers
Tongxin xuebao, 2018 Firstly,based on three subsets division property propagation technique,the propagation function of the K-set and L-set of ARX block ciphers was constructed respectively.All vectors in L-set affected the propagation of K-set when propagate through xored ...
