Throwing Boomerangs into Feistel Structures
IACR Transactions on Symmetric Cryptology, 2022 Automatic tools to search for boomerang distinguishers have seen significant advances over the past few years. However, most previous work has focused on ciphers based on a Substitution Permutation Network (SPN), while analyzing the Feistel structure is

A Modification of TEA Block Cipher Algorithm for Data Security (MTEA) [PDF]
Engineering and Technology Journal, 2011 This paper attempts to develop a simple, stronger and safer cryptographic algorithm which would not only be a secure one, but also reduces total time taken for encryption and decryption.

Journal of Advances in Modeling Earth Systems, Volume 15, Issue 10, October 2023., 2023 Abstract We address the question of how to use a machine learned (ML) parameterization in a general circulation model (GCM), and assess its performance both computationally and physically. We take one particular ML parameterization (Guillaumin & Zanna, 2021, https://doi.org/10.1002/essoar.10506419.1) and evaluate the online performance in a different ...

IET Image Processing, Volume 17, Issue 10, Page 2984-3001, 21 August 2023., 2023 In IoT sensors, which are used to record and send images, secure image transmission is of great importance. Therefore, we need to use encryption, watermarking and compression processes. Here, a new integrated method of lightweight encryption, watermarking and compression for the fast and secure transmission of images is proposed.

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 ...

Differential analysis of the NBC algorithm based on mixed integer linear programming model
SECURITY AND PRIVACY, Volume 6, Issue 4, July/August 2023., 2023 Abstract This paper mainly studies mixed integer linear programming (MILP)‐based cryptanalysis on round‐reduced NBC algorithm with generalized Feistel structure. First, each component of the algorithm is equivalently described by linear inequality equations, and the propagation rules of differential characteristics and linear approximation are ...
