Cross-Database Liveness Detection: Insights from Comparative Biometric Analysis

In an era where biometric security serves as a keystone of modern identity verification systems, ensuring the authenticity of these biometric samples is paramount. Liveness detection, the capability to differentiate between genuine and spoofed biometric samples, stands at the forefront of this challenge. This research presents a comprehensive evaluation of liveness detection models, with a particular focus on their performance in cross-database scenarios, a test paradigm notorious for its com...

Performance analysis of symmetric encryption algorithms for time-critical cybersecurity application

This study presents a comprehensive performance analysis of symmetric encryption algorithms in the context of time-critical cybersecurity applications. We evaluate a diverse set of algorithms, including established standards and emerging ciphers, across multiple performance metrics relevant to resource-constrained and latency-sensitive environments. Our methodology encompasses rigorous testing of stream encryption speed, packet encryption efficiency, and key/IV setup times on a standardized h...

Stochastic Modeling of Path Length Dynamics in Ethereum’s Merkle Patricia Tries

This study presents a novel probabilistic framework for analyzing path length distributions in Merkle Patricia Tries, the foundational data structure of Ethereum’s state management system. We develop a mathematical model characterizing the probability distribution of path lengths for randomly generated Ethereum addresses and validate it through extensive computational simulations. Our findings reveal the logarithmic growth of average path lengths with respect to the number of addresses, confi...
