On the Derivative Imbalance and Ambiguity of Functions

, 2018
In 2007, Carlet and Ding introduced two parameters, denoted by $Nb_F$ and $NB_F$, quantifying respectively the balancedness of general functions $F$ between finite Abelian groups and the (global) balancedness of their derivatives $D_a F(x)=F(x+a)-F(x)$, $

Hardware Design for Secure Telemedicine Using A Novel Framework, A New 4D Memristive Chaotic Oscillator, and Dispatched Gray Code Scrambler

Engineering Reports, Volume 7, Issue 10, October 2025.
This work presents a secure telemedicine cryptosystem based on a novel 4D memristive chaotic oscillator and a Dispatched Gray Code Scrambler (DGCS). Implemented on FPGA, the system ensures power‐efficient encryption, making it suitable for real‐time medical image transmission in IoT healthcare environments.

Cryptanalysis of Reduced-Round SPECK

IEEE Access, 2019
SPECK, a family of lightweight block ciphers proposed by the National Security Agency (NSA), is widely used under resource constrained environment. There are many cryptanalytic results on SPECK concentrated on differential and linear attacks.

On the Embedded of a Fast, Light and Robust Chaos‐Based Cryptosystem in NEXYS4 FPGA Card for Real Time Color Image Security (CBC in N‐FPGA‐RTCIP)

Engineering Reports, Volume 7, Issue 9, September 2025.
Security evaluation, NPCR + UACI results of 99.5978% and 33.4549% respectively, confirm the system is secure against statistical and differential attacks. Besides, the FPGA implementation achieves low power of 115 mW at a speed of 42.56 MHz. This makes it suitable for IoT applications where power and hardware resources are constrained. ABSTRACT In this

Related-Key Differential Attacks on COSB-128

International Journal of Distributed Sensor Networks, 2015
COSB-128 (Moldovyan et al., 2002) is a block cipher with 128-bit and 256-bit secret keys, which use key and data-dependent operational substitutions in fast controllable permutation blocks (CPB) concept.

Combining Real‐World and Clinical Trial Data Through Privacy‐Preserving Record Linkage: Opportunities and Challenges—A Narrative Review

Health Science Reports, Volume 8, Issue 9, September 2025.
ABSTRACT Background and Aims Despite their widespread use, randomized clinical trials (RCTs) face challenges like differential loss to follow‐up, which can impact validity. Real‐world evidence (RWE) from real‐world data (RWD) is increasingly used to address these limitations, but RCTs and RWE have provided complementary, disconnected observations of ...

Security against differential and linear cryptanalysis for general SPT models

Tongxin xuebao, 2012
To use SP network in stream ciphers safely and efficiently,the ability against differential and linear cryptanalysis of SPT models was studied,where S and T denote different layers for substitution,in which compression could be achieved,and P denotes the

Automated Risk‐Based Cryptoperiod Calculation in ICSs: Analytical Framework and Software Tool

SECURITY AND PRIVACY, Volume 8, Issue 5, September/October 2025.
ABSTRACT Internal network and system reconnaissance is one of the first crucial stages of most cyber attacks, though it plays an especially important role in attacks on complex industrial control systems (ICSs) that span both IT and OT environments. Frequently, besides device enumeration and scanning, a malicious ICS reconnaissance campaign will also ...

Generating Graphs Packed with Paths Estimation of Linear Approximations and Differentials

IACR Transactions on Symmetric Cryptology, 2018
When designing a new symmetric-key primitive, the designer must show resistance to known attacks. Perhaps most prominent amongst these are linear and differential cryptanalysis. However, it is notoriously difficult to accurately demonstrate e.g.
