Title:
TentLogiX: 5-bit Chaos-Driven S-Boxes for Lightweight Cryptographic Systems
Authors: Maha Allouzi, Arefeh Rahaei
Abstract:Cryptography is a crucial method for ensuring the security of communication and data transfers across networks. While it excels on devices with abundant resources, such as PCs, servers, and smartphones, it may encounter challenges when applied to resource-constrained Internet of Things (IoT) devices like Radio Frequency Identification (RFID) tags and sensors. To address this issue, a demand arises for a lightweight variant of cryptography known as lightweight cryptography (LWC).
In developing any cryptographic algorithm, the substitution box (S-box) is a fundamental component, providing nonlinear functionality between inputs and outputs. Researchers have TentLogiX diverse S-box designs tailored for various applications, but only a few manage to balance the trade-offs among cost, performance, and security, particularly in the context of resource-constrained IoT devices.
This paper delves into the realm of S-boxes employed in popular LWC algorithms, categorizing them by their input–output bit sizes and elucidating their strengths and limitations. The focus then shifts to a novel 5-bit S-box design, utilizing chaotic mapping theory to introduce a randomized behavior.
Subsequently, the paper proposed TentLogiX a 5-bit S-box, constructed based on compound chaotic system, tent-logistic systems, which has better chaotic performance and wider sequences and explores its security robustness through various cryptanalysis techniques, including bijective analysis, nonlinearity assessment, linearity evaluation, and differential cryptanalysis. The paper concludes by presenting a thorough comparison that underscores the superiority of the TentLogiX 5-bit S-box over its 5-bit counterparts.
