Algebraic Precomputations in Differential Cryptanalysis

open access: yes, 2010
Algebraic cryptanalysis is a general tool which permits one to assess the security of a wide range of cryptographic schemes. Algebraic techniques have been successfully applied against a number of multivariate schemes and stream ciphers. Yet, their feasibility against block ciphers remains the source of much speculation.

Related-Key Differential Attacks on COSB-128

open access: yesInternational 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.

Cryptanalysis of NBC-128

open access: yesDianzi Jishu Yingyong, 2021
NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.

System approach to disparity estimation [PDF]

open access: yes, 1995
A system approach to disparity estimation using dynamic programming is presented. The four step system can calculate a dense correspondence map between a stereo pair with parallel or nonparallel camera geometry.

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)

open access: yesEngineering 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

Breaking a Chaotic Cryptographic Scheme Based on Composition Maps

open access: yes, 2009
Recently, a chaotic cryptographic scheme based on composition maps was proposed. This paper studies the security of the scheme and reports the following findings: 1) the scheme can be broken by a differential attack with $6+\lceil\log_L(MN)\rceil$ chosen-

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

open access: yesHealth 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 ...

Commutative Cryptanalysis Made Practical

open access: yesIACR Transactions on Symmetric Cryptology, 2023
About 20 years ago, Wagner showed that most of the (then) known techniques used in the cryptanalysis of block ciphers were particular cases of what he called commutative diagram cryptanalysis.
