Reinforcing Cloud Attack Tolerance on a Large Scale: Advanced Blockchain Technologies With Hierarchical Risk and Smart Contracts

IET Blockchain, Volume 5, Issue 1, January/December 2025.
We propose a blockchain‐based system to enhance cloud systems' resilience against distributed denial of service attacks. Our approach integrates a hierarchical risk‐based attack tolerance mechanism with smart contracts, dynamically estimating risks at local, cluster, and global levels using Dempster–Shafer theory. Simulations show improved availability,

A Method of Detections’ Fusion for GNSS Anti-Spoofing

Sensors, 2016
The spoofing attack is one of the security threats of systems depending on the Global Navigation Satellite System (GNSS). There have been many GNSS spoofing detection methods, and each of them focuses on a characteristic of the GNSS signal or a ...

Distribution‐Matched Imputation for Incomplete Data Evidential Classification

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper introduces a novel distribution‐matched imputation (DMI) method that leverages evidential reasoning to address classification challenges in datasets with missing values, optimizing weights to minimize the inconsistency between training and test sets.

An Extension to Deng’s Entropy in the Open World Assumption with an Application in Sensor Data Fusion

Sensors, 2018
Quantification of uncertain degree in the Dempster-Shafer evidence theory (DST) framework with belief entropy is still an open issue, even a blank field for the open world assumption.

Reliability Analysis Based on Aleatory and Epistemic Uncertainty Using Binary Decision Diagrams

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
The development of a mathematical model is an important step in reliability analysis. However, initial data are often not clearly defined, and some necessary information about the system’s behavior may be missing. Most mathematical models in reliability analysis primarily address aleatory uncertainty.

Expert System for Early Childhood Talent Detection Using Certainty Factor and Dempster Shafer Algorithms

Journal of Information Systems and Informatics
Early life is a crucial window for recognizing children’s interests and talents that shape later development. This study implements and compares two reasoning algorithms—Certainty Factor (CF) and Dempster–Shafer Theory (DST)—within a rule-based expert ...

Dynamic Twitter friend grouping based on similarity, interaction, and trust to account for ever‐evolving relationships

IET Communications, Volume 18, Issue 17, Page 1018-1048, October 2024.
The proposed study aims to enhance online privacy within social networking platforms by categorizing users into three trust levels (acquaintances, friends, close friends) based on engagement and trust. The method dynamically adjusts relationship status over time, considering past and present offenses, offering a more realistic simulation of real‐world ...
