Towards a lightweight security framework using blockchain and machine learning

Cyber-attacks pose a significant challenge to the security of Internet of Things (IoT) sensor networks, necessitating the development of robust countermeasures tailored to their unique characteristics and limitations. Various prevention and detection techniques have been proposed to mitigate these attacks. In this paper, we propose an integrated security framework using blockchain and Machine Learning (ML) to protect IoT sensor networks. The framework consists of two modules: a blockchain prevention module and an ML detection module. The blockchain prevention module has two lightweight mechanisms: identity management and trust management. Identity management employs a lightweight Smart Contract (SC) to manage node registration and authentication, ensuring that unauthorized entities are prohibited from engaging in any tasks, while trust management uses a lightweight SC that is responsible for maintaining trust and credibility between sensor nodes throughout the network's lifetime and tracking historical node behaviors. Consensus and transaction validation are achieved through a Verifiable Byzantine Fault Tolerance (VBFT) mechanism to ensure network reliability and integrity. The ML detection module utilizes the Light Gradient Boosting Machine (LightGBM) algorithm to classify malicious nodes and notify the blockchain network if it must make decisions to mitigate their impacts. We investigate the performance of several off -the -shelf ML algorithms, including Logistic Regression, Complement Naive Bayes, Nearest Centroid, and Stacking, using the WSN-DS dataset. LightGBM is selected following a detailed comparative analysis conducted using accuracy, precision, recall, F1 -score, processing time, training time, prediction time, computational complexity, and Matthews Correlation Coefficient (MCC) evaluation metrics.

作者： Fangqin Cheng Na Zhou Nazeer muhammad nouman Li Cui Caixia Yin Institute of Resources and Environmental Engineering State Environmental Protection Key Laboratory of Efficient Utilization of Coal Waste Resources Shanxi University Key Laboratory of Chemical Biology and Molecular Engineering of Ministry of Education Institute of Molecular ScienceShanxi University

In recent years, the demand for strategic metal resources, essential for scientific and technological progress and industrial development, has multiplied. Ensuring a stable supply of these metals is critical to national security and the well-being of the population. As global industrialization accelerates, the daily demand for nonferrous metals continues to rise. Consequently,extracting and recovering strategic metals from low-grade raw materials, such as solid waste, has become crucial for maintaining their supply and economic development. However, the extraction process is fraught with challenges, including mineral phase stability and complex composition. This review focuses on key strategic metals such as lithium, aluminum, gallium, and vanadium. It introduces and examines various methods for extracting nonferrous metals from different raw materials, including traditional mining technologies applied to low-grade solid wastes. It also outlines future development opportunities and challenges in this field.

Gastrointestinal diseases like ulcers, polyps’, and bleeding areincreasing rapidly in the world over the last decade. On average 0.7 millioncases are reported worldwide every year. The main cause of gastrointestinaldiseases is a Helicobacter Pylori (H. Pylori) bacterium that presents in morethan 50% of people around the globe. Many researchers have proposeddifferent methods for gastrointestinal disease using computer vision *** of them focused on the detection process and the rest of themperformed classification. The major challenges that they faced are the similarityof infected and healthy regions that misleads the correct classificationaccuracy. In this work, we proposed a technique based on Mask Recurrent-Convolutional Neural Network (R-CNN) and fine-tuned pre-trainedResNet-50 and ResNet-152 networks for feature extraction. Initially, the region ofinterest is detected using Mask R-CNN which is later utilized for the trainingof fine-tuned models through transfer learning. Features are extracted fromfine-tuned models that are later fused using a serial approach. Moreover, anImproved Ant Colony Optimization (ACO) algorithm has also opted for thebest feature selection from the fused feature vector. The best-selected featuresare finally classified using machine learning techniques. The experimentalprocess was conducted on the publicly available dataset and obtained animproved accuracy of 96.43%. In comparison with state-of-the-art techniques,it is observed that the proposed accuracy is improved.

在本文中,提出了加权最小二乘法、共轭梯度法和双共轭梯度稳定法用于潮流计算的有效技术。所提出的方法基于在牛顿-拉夫森(N-R)方法中求解一组线性方程的迭代方法。BICGSTAB方法是扩展共轭梯度方法的变体之一,具有良好的收敛特性。迄今为止,直接法已被用于求解一组线性方程组。然而,众所周知,在数值分析中,诸如IC(不完全Cholesky)和ILU(不完全上下)分解等预处理迭代方法对于求解一组线性方程很有用。加快大型电力系统的潮流计算。对于对称正定(SPD)矩阵,我们将使用不完全Cholesky预处理CG迭代方法,对于非对称矩阵,我们使用不完全LU预处理BICGSTAB迭代方法。使用MATLAB软件和C语言生成的结果和从MATPOWER扩展文件收集的总线预测数据。被使用。本论文报告了在IEEE 14、30和57节点系统上测试直接法和间接法的结果,并比较了收敛时间和迭代次数。
