Distribution of the best nonzero differential and linear approximations of s-box functions
In the paper the differential and the linear approximations of two classes of s-box functions are considered. The classes are the permutations and arbitrary functions with n binary inputs and m binary outputs, where 1≤n=m≤10.

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

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 ...

Enhancing Differential-Linear Cryptanalysis [PDF]
Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linear relations. In 1994, Langford and Hellman showed that both kinds of analysis can be combined together by a technique called differential-linear cryptanalysis, in which the ...

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