Obfuscated malware adds layers of difficulty to detect complex modern cyber attacks by evading AI-enabled Next-Generation Anti-Virus (NGAV) scanners and breaching digital privacy. To tackle this problem, in this paper, we propose “Augmented Sparse Projection Oblique Random Forest (AugSPORF)”, an Explainable sparse projections based Oblique Random Forest (ORF) with Isolated Family Distinction (IFD) Paradigm to detect multiple obfuscated malware belonging to Spyware, Ransomware, and Trojan families effectively. Irrespective of obfuscation, malware variants possess common behavior and family traits aligned with their families and leave traces in the memory on execution. To begin with this motivation, we handle the huge dimension of memory forensic features with sparse random projections. Next, we perform feature importance aware training with ORF to learn inherent behavioral features of malware families by isolating the target family, and distinguishing with other families. Further, the model’s scalability is assessed by increasing the number of malware families. To offer an insightful conclusion on the predictions, an Interpretable Machine Learning (IML) layer is interleaved to generate a report of explanations, thereby enhancing the interpretability of the model. The proposed approach yields an average accuracy of 96.76%, 96.45%, and 97.33% in detecting sub-families of Spyware, Ransomware, and Trojan respectively. Improved accuracy is also demonstrated by benchmarking the performance of AugSPORF on UCI repository datasets.</div></div>","PeriodicalId":50630,"journal":{"name":"Computers & Electrical Engineering","volume":"123 ","pages":"Article 110107"},"PeriodicalIF":4.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Where the unavailability of an efficient routing path leads to consumption of energy at nodes. In addition to this, it has been found that the nodes may get stuck at points where no path is available in the forward direction, while dealing with data transfer in a large geographical space. The non-availability of the forward path leads to the creation of void node problem (VNP). However, the literature revealed that the anchor-based methods are utilized to detour from VNP, but this leads to the overloading of the anchor node when multiple sources traverse the same path. So, this paper proposes a novel energy-efficient anchor zone-based routing (EAZR) protocol, where, the traffic passes through different nodes of the anchor zone rather than a single anchor node. The proposed protocol effectively divides the traffic among multiple nodes based on residual energy and this minimizes the energy consumption during data transmission in 3D resource-constrained IoT networks. This proposed method has been implemented using OMNET++ simulator and obtained simulation results have shown its supremacy over existing state-of-art techniques in terms of energy consumption, network lifetime, and other quality of service (QoS) parameters.</div></div>","PeriodicalId":50630,"journal":{"name":"Computers & Electrical Engineering","volume":"123 ","pages":"Article 110144"},"PeriodicalIF":4.0,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These studies utilized computationally intensive dynamic current analysis methods to account for the significant dynamic effects incurred.

A high torque density 8/18 OR-multi-teeth (MT) SRM topology has been proposed. The benefits of this topology, such as mass, cost, torque ripple reductions, and improved torque density, have been highlighted through a comparison with a conventional 6/10 OR-SRM topology. The reliability of the finite element analysis models used in this study is validated through experiments conducted on an 8/18 OR-MTSRM prototype.

To combat these challenges, we propose a privacy-preserving and robust aggregation scheme for multi-dimensional data in VANETs.

Multi-criteria recommendation systems has attracted significant attention in the field of recommendation systems due to the lower accuracy of single-criteria recommendation systems.
