Characterization of Portable Ultra‐Low Field MRI Scanners for Multi‐Center Structural Neuroimaging

Human Brain Mapping, Volume 46, Issue 8, June 1, 2025.
A global study on quality control of portable, ultra‐low field MRI systems within the UNITY network. Cross‐sectional and longitudinal data are presented together with analysis of factors influencing image noise, contrast, and distortions. ABSTRACT The lower infrastructure requirements of portable ultra‐low field MRI (ULF‐MRI) systems have enabled their

Yoyo Cryptanalysis Against Reduced‐Round L‐Feistel Structure for Recovering the Secret Components

IET Information Security, Volume 2025, Issue 1, 2025.
L‐Feistel structure is a new iterative block cipher structure and unifies the Feistel structure and the Lai–Massey structure while maintaining the similarity of encryption and decryption. In this study, we present the first yoyo cryptanalysis against the L‐Feistel structure to evaluate the security under structural attack and give the method to recover

Bit‐Based Evaluation of Lightweight Block Ciphers SLIM, LBC‐IoT, and SLA by Mixed Integer Linear Programming

IET Information Security, Volume 2024, Issue 1, 2024.
Many lightweight block ciphers have been proposed for IoT devices that have limited resources. SLIM, LBC‐IoT, and SLA are lightweight block ciphers developed for IoT systems. The designer of SLIM presented a 7‐round differential distinguisher and an 11‐round linear trail using a heuristic method. We have comprehensively sought the longest distinguisher

Automated Differential‐Linear Cryptanalysis for AND‐RX Ciphers

IET Information Security, Volume 2024, Issue 1, 2024.
Differential and linear cryptanalysis are two important methods to evaluate the security of block ciphers. Building on these two methods, differential‐linear (DL) cryptanalysis was introduced by Langford and Hellman in 1994. This cryptanalytic method has been not only extensively researched but also proven to be effective.
