However, existing solutions focus only on user anonymity and are severely exposed to fake energy offers that can lead to denial-of-service attacks. Moreover, the off-chain communication mechanism used for private energy negotiation is computationally inefficient. This paper proposes a Multi-Level Privacy-Preserving system (MuLPP) for blockchain-based bilateral P2P-ET that provides user anonymity, energy price and energy amount privacy while protecting against fake energy offers. To address the privacy concerns in a comprehensive way, MuLPP offers three levels of privacy: public-level, energy authority-level and participant-level. MuLPP is based on blockchain smart contracts, RSA accumulators, public key aggregation and BLS-based multi-signature to achieve user anonymity, data privacy, robustness against fake energy offers and security in off-chain negotiation. This paper also proposes a permissioned anonymous decentralized P2P off-chain communication protocol, known as PADPeC, to enhance the privacy and performance of off-chain energy negotiations. Experimental results conducted in a real environment indicate that MuLPP provides 75 to 100 times lower on-chain latency. On the other hand, PADPeC reduces the message-sending time and the number of message exchanges in the off-chain communication by a factor of 4123 and 7.88 respectively compared to the existing systems. Formal security verification conducted using AVISPA security verification tool also revealed that the system is secure against various attacks such as sybil, network flooding and fake energy offer attack.</div></div>","PeriodicalId":54784,"journal":{"name":"Journal of Network and Computer Applications","volume":"237 ","pages":"Article 104141"},"PeriodicalIF":7.7,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, by analyzing the geographic properties of contact tracing in crisis, we first construct a Voronoi diagram map for detailed disaster-related data collection and management. Then, we introduce Hazardous Monitoring for broadcasting disaster information, which enables citizens to conveniently receive updates from public crisis management departments and rapidly recognize potential risks. In addition, we design Secure Exposure Identification, leveraging the Voronoi diagram and homomorphic encryption-based Private Set Intersection (PSI), allowing citizens to securely trace and identify contact with infected individuals. Detailed security analysis confirms that PRISM effectively safeguards citizens against privacy breaches.

The current solutions fail to balance security and efficiency. To address insecure interactions arising from producer mobility, we introduce a protocol for blockchain-based mobile producer authentication (BAS-NDN). Our protocol relies on a novel elliptic curve-based certificateless signcryption scheme, which is easy to deploy, provides both signature and encryption, and avoids complex certificate management and key escrow problems. This makes it suitable for secure and efficient mobile management in NDN. In addition, the proposed scheme efficiently authenticates the producer’s prefixes by enforcing the producer to publish routing updates that use only valid prefixes. This design renders it resistant to prefix hijacking attacks. Through analyzing under the random oracle model, it is also resistant to both Type I and Type II adversaries present in certificateless signcryption.

Cloud computing presents a significant obstacle to efficient resource usage and balance of loads due to the dynamic nature of consumer requirements and tasks. The inflexibility of conventional methods guarantees inadequate outcomes and waste of resources. Motivated by improved cloud infrastructure management, the present research introduces a novel approach to load optimization and migrating Virtual Machines (VMs) based on agents modelled and Internet of Things (IoT) devices. This research aims to boost cloud performance primarily by optimizing the utilization of resources and distribution of workloads. Hence, a novel approach, the Optimized Virtual Machine Migration Scheme (OVMMS), is introduced that uses the Squirrel Search Algorithm (SSA) for migrating VMs. By emulating squirrel behaviour during migration and search, these agents maximize load balance and the distribution of resources. During the analysis, IoT devices were enabled to monitor and control cloud resources to minimize wastage. Results from experimental analysis demonstrate that the proposed strategy outperforms the state-of-the-art in numerous key areas, including service dissemination, load mitigation, managing failures, mitigating time, and endurance of VM. The results show that the number of failures and the time it takes to mitigate them have dropped dramatically, while services' efficiency and distribution rates have improved substantially. The results illustrate that the squirrel-driven approach holds significant potential for addressing vital issues in cloud computing scenarios. This method asserts that optimizing the distribution of resources and the allocation of workloads may improve systems adaptability, service dependability, and cloud infrastructure operations. The proposed scheme maximizes load mitigation by 11.59%, service dissemination by 8.1%, and VM availability by 8.56%, reducing failures by 12.12% for the maximum service providers.</div></div>","PeriodicalId":54784,"journal":{"name":"Journal of Network and Computer Applications","volume":"237 ","pages":"Article 104137"},"PeriodicalIF":7.7,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing cloud-native security applications utilize a combination of rule-based and machine learning-based detection techniques to protect digital assets. However, these approaches have limitations. Rule-based detection depends on predefined rules to identify specific attack patterns. Persistent attackers can often evade detection by carefully ensuring that their behavior circumvents these rules. In contrast, machine learning-based detection techniques, which learn attack patterns from data, rely heavily on the availability of labeled data for training. However, labeled data is often unavailable and can be labor-intensive and costly to obtain. In this paper, we address the challenge of detecting APT attacks more holistically by leveraging attackers’ behavior during communication with Command and Control (C2) servers, a critical phase observed in most APT attacks. We aim to reduce false positive alerts for threat hunters by analyzing system network logs to detect potential network beaconing, a common attribute of various malware. We introduce a novel hybrid approach, called <em><strong>NetSpectra Sentinel</strong></em>, which employs a Continuous Time Hidden Markov Model (CT-HMM) to detect hidden states underlying observed patterns within the network logs and Time Series Decomposition (TSD) to model temporal patterns.

The results demonstrate that our technique achieves significantly higher accuracy in most cases, and even when existing techniques fail, our approach can still detect beaconing post-initial compromise with up to 90% accuracy.
