This study addresses the critical challenge of achieving reliable message exchange among vehicles in Vehicular Ad-hoc Networks (VANETs). It is crucial to quickly share safety messages, traffic updates, available services, and road conditions among vehicles in VANETs. For security reasons, messages must originate exclusively from authenticated vehicles, ensuring secure message exchange and data privacy. Numerous schemes for privacy-preserving authentication have been proposed, yet they suffer from constant service provider involvement and the requirement for vehicles to generate parameters on the fly. To address these challenges, this paper introduces LbPV, a secure lattice-based privacy-preserving mutual authentication scheme emphasizing the reliability of messages, preventing spoofing and unauthorized access. LbPV eliminates service provider monitoring and allows vehicles to authenticate messages without generating parameters while on the move. This is achieved by exchanging a confidential token using lattice-based encryption and message signing. By verifying the signed message and using the shared token, receiving vehicles can confirm the authenticity of the messages. By using lattice-based cryptography, the proposed protocol is also designed with the potential to resist future attacks, including quantum attacks, enhancing its long-term security viability. The security analysis of LbPV includes formal and informal evaluations that demonstrate its robustness. Performance evaluations using the NTL library show that LbPV, with service provider parameters, outperforms existing approaches in the literature. Results of performance analysis indicate that when compared to the most efficient traditional non-lattice-based scheme discussed in this paper, the proposed protocol has increased computation cost, communication cost, and power consumption by 77.71%, 98.58%, and 77.71%, respectively. Conversely, when compared to the most efficient lattice-based scheme discussed in this paper, the proposed scheme demonstrates reductions in computation cost, communication cost, and power consumption by 71.95%, 2.16%, and 71.95%, respectively.

本研究探讨了在车载 Ad-hoc 网络 (VANET) 中实现车辆间可靠信息交换的关键挑战。在 VANET 中，车辆之间快速共享安全信息、交通更新、可用服务和路况至关重要。出于安全考虑，信息必须仅来自经过认证的车辆，以确保信息交换安全和数据隐私。目前已经提出了许多保护隐私的认证方案，但这些方案都存在服务提供商不断参与和车辆需要即时生成参数的问题。为了应对这些挑战，本文介绍了 LbPV，这是一种基于网格的安全隐私保护相互验证方案，强调信息的可靠性，防止欺骗和未经授权的访问。LbPV 消除了服务提供商的监控，允许车辆在移动过程中验证信息而无需生成参数。这是通过使用基于网格的加密和信息签名交换保密令牌来实现的。通过验证签名信息和使用共享令牌，接收车辆可以确认信息的真实性。通过使用基于网格的加密技术，所提出的协议还具有抵御未来攻击（包括量子攻击）的潜力，从而增强了其长期安全性。LbPV 的安全性分析包括正式和非正式评估，以证明其稳健性。使用 NTL 库进行的性能评估表明，LbPV 在带有服务提供商参数的情况下，性能优于文献中的现有方法。性能分析结果表明，与本文讨论的最有效的传统非网格方案相比，所提出的协议在计算成本、通信成本和功耗方面分别增加了 77.71%、98.58% 和 77.71%。相反，与本文讨论的最有效的基于网格的方案相比，拟议方案的计算成本、通信成本和功耗分别降低了 71.95%、2.16% 和 71.95%。

Recently, coverless steganography has been gaining popularity in confidential information-hiding techniques due to its resistance to the detection of steganalysis. Whereas most coverless approaches are based on images as the transmission medium, few articles are based on video in coverless steganography. Whereas the hiding capacity per frame in the existing scheme is less, and to improve the capacity, a new secret data sharing through coverless video steganography is proposed based on the average Direct Current (DC) coefficient on the Bit plane. The bit planes are extracted from the video frame, generating multiple hash sequences from each bit plane. The bit plane is further partitioned into blocks. The average DC coefficient of consecutive subblocks within a block in a bit plane frame is compared to create the hash bit sequences. A video index database is created to store the generated hash sequences for easy retrieval. The receiver successfully recovered the secret information from the retrieval information and received videos. The observed findings show that the suggested method outperforms recent coverless video steganography techniques. The robustness is substantially stronger and superior to other existing schemes.

最近，无掩盖隐写术因其抗隐写分析检测的能力而在机密信息隐藏技术中越来越受欢迎。大多数无掩码方法都是以图像作为传输介质，而很少有文章以视频作为无掩码隐写术的传输介质。现有方案中每帧的隐藏能力较低，为了提高隐藏能力，提出了一种基于比特平面上平均直流（DC）系数的新的无掩盖视频隐写术秘密数据共享方法。从视频帧中提取位平面，从每个位平面生成多个哈希序列。位平面被进一步分割成块。比较位平面帧中一个块内连续子块的平均直流电系数，以创建哈希位序列。创建一个视频索引数据库来存储生成的哈希序列，以便于检索。接收器成功地从检索信息和接收到的视频中恢复了秘密信息。观察结果表明，所建议的方法优于最新的无掩码视频隐写技术。其稳健性大大强于其他现有方案。

Software Defined Network (SDN) offers virtualized services compatible with infrastructure hosted computing, presenting a flexible, adaptive, and economical network architecture. Switches used in SDN prioritize packet matching in flow tables above packet processing, leaving them open to Denial of Service (DoS) attacks. These attacks, exemplified by Distributed Denial of Service Attacks (DDoS), target a victim while using many infected workstations at once. Due to its scalability and programmability, SDN is being used more and more for network management. However, it has specific security concerns, such as the controller’s susceptibility to cyberattacks, which might result in a single point of failure and network-wide risks. This study proposes a novel DDoS prediction model by developing stacking classifier model consisting of multiple base classifiers for an SDN environment. The proposed model is built on stacking several classifiers at the base level and the Meta level, which mixes varied or heterogeneous learners to provide reliable model results. The findings demonstrate that the proposed stacking model outperforms other existing models with respect to accuracy, sensitivity, specificity, precision, and F1 score. Finally, the stacking classifier model is evaluated in terms of binary classification. The evaluation shows the highest AUC of 0.9537 whereas Random Forest, Decision Tree, and Logistic Regression achieve AUC values around 0.93–0.95.

软件定义网络（SDN）提供与基础设施托管计算兼容的虚拟化服务，是一种灵活、自适应和经济的网络架构。SDN 中使用的交换机将流量表中的数据包匹配优先级置于数据包处理之上，从而使其容易受到拒绝服务 (DoS) 攻击。这些攻击以分布式拒绝服务攻击（DDoS）为例，目标是同时使用许多受感染工作站的受害者。由于具有可扩展性和可编程性，SDN 被越来越多地用于网络管理。然而，它也有一些特定的安全问题，如控制器易受网络攻击，可能导致单点故障和全网风险。本研究通过为 SDN 环境开发由多个基础分类器组成的堆叠分类器模型，提出了一种新型 DDoS 预测模型。所提出的模型是在基础层和元层堆叠多个分类器而建立的，它混合了不同或异构的学习者，以提供可靠的模型结果。研究结果表明，所提出的堆叠模型在准确度、灵敏度、特异性、精确度和 F1 分数方面都优于其他现有模型。最后，从二元分类的角度对堆积分类器模型进行了评估。评估结果显示，AUC 最高，为 0.9537，而随机森林、决策树和逻辑回归的 AUC 值约为 0.93-0.95。

Efficient distribution of active and reactive power in distribution networks is crucial for ensuring that consumer demand is met and that electrical power quality is maintained. This requires careful planning, particularly in terms of optimally placing and sizing distributed generator (DG) and capacitor bank (CB) units. These units play a key role in minimizing power losses and voltage fluctuations within the network. However, implementing DG and CB units in unbalanced distribution networks presents unique challenges due to inherent system unbalances. To address these challenges, this article proposes a method for allocating and sizing DG and CB units in unbalanced distribution networks. The approach accounts for the network's unbalance and targets multiple objectives, such as reducing power losses, improving multi-phase voltage stability, and minimizing phase-to-phase voltage unbalance. The fast and flexible radial power flow (FFRPF) technique is employed to model complex interactions and constraints within the network, leading to a multi-objective optimization problem. This optimization problem is solved using the weight aggregated particle swarm optimization (WA-PSO) method, a variant of particle swarm optimization tailored for multi-objective functions. WA-PSO simplifies the process by combining multiple objectives into a single function using weighted aggregation. The efficacy of this approach is validated on 19, 34, and 123-node unbalanced radial distribution networks (URDNs). The results show significant improvements in power delivery efficiency across all tested networks, especially when DG and CB units are operated simultaneously. Specifically, DG and CB integration led to a reduction in system losses by 89.90 %, 88.42 %, and 86.87 %, and a decrease in three-phase voltage unbalance indices by 88.75 %, 81.68 %, and 39.05 %, for the 19, 34, and 123-node systems, respectively, while maintaining voltage stability within acceptable limits. Additionally, CO₂ emissions were reduced by 52 %, 62 %, and 53 % when microturbines were utilized instead of coal-based thermal power plants, further highlighting the environmental benefits of the proposed approach.

配电网络中有功和无功功率的有效分配对于确保满足用户需求和保持电能质量至关重要。这需要精心规划，特别是在优化分布式发电机 (DG) 和电容器组 (CB) 的布置和大小方面。这些设备在最大限度减少电网内的电力损耗和电压波动方面发挥着关键作用。然而，由于固有的系统不平衡，在不平衡配电网络中实施分布式发电机和电容器组单元面临着独特的挑战。为了应对这些挑战，本文提出了一种在不平衡配电网络中分配和确定 DG 和 CB 单元大小的方法。该方法考虑了配电网的不平衡性，并以降低功率损耗、改善多相电压稳定性和最大限度减少相间电压不平衡等多个目标为目标。该方法采用快速灵活的径向功率流（FFRPF）技术来模拟网络内复杂的相互作用和约束条件，从而产生一个多目标优化问题。该优化问题采用权重聚合粒子群优化（WA-PSO）方法解决，该方法是粒子群优化的一种变体，专为多目标函数量身定制。WA-PSO 利用加权聚合法将多个目标合并为一个函数，从而简化了过程。这种方法的有效性在 19、34 和 123 节点的不平衡径向配电网络 (URDN) 上得到了验证。结果表明，所有测试网络的电力输送效率都有明显改善，尤其是当 DG 和 CB 设备同时运行时。具体而言，在 19 节点、34 节点和 123 节点系统中，DG 和 CB 的集成使系统损耗分别降低了 89.90 %、88.42 % 和 86.87 %，三相电压不平衡指数分别降低了 88.75 %、81.68 % 和 39.05 %，同时将电压稳定性保持在可接受的范围内。此外，当使用微型涡轮机替代燃煤火力发电厂时，二氧化碳排放量分别减少了 52%、62% 和 53%，进一步凸显了拟议方法的环境效益。

Misoperation when a driver is distracted, e.g., turning the steering wheel unconsciously, preventing the machine from turning the steering wheel, etc., can lead to a false take-over of the vehicle, which poses a danger to shared control. Therefore, it is essential to evaluate the feasibility of driver take-over in distraction status. This paper proposes a steering authority allocation strategy based on driver take-over feasibility to reduce the interference of distracted driver behavior on shared control. First, a driver take-over feasibility framework is established based on quantified driver distraction levels and take-over intention. Then the shared control system is established based on a linear parameter-varying vehicle model and non-cooperative game theory to suppress the interference of time-varying speed and parameter uncertainty on shared control. Subsequently, the steering authority allocation strategy is constructed in conjunction with driver take-over feasibility and environmental risk evaluation. The proposed sigmoid-based mapping function ensures fast and smooth authority allocation. Finally, a series of driver-in-the-loop experiments are conducted to validate the effectiveness of our proposed strategy across various driving scenarios, and the results demonstrate that our strategy has superior performance than other advanced shared control schemes in reducing steering burden, improving driving safety, and enhancing vehicle stability, etc.

驾驶员分心时的错误操作，如无意识转动方向盘、阻止机器转动方向盘等，会导致错误接管车辆，从而给共享控制带来危险。因此，评估分心状态下驾驶员接管的可行性至关重要。本文提出了一种基于驾驶员接管可行性的转向权限分配策略，以减少驾驶员分心行为对共享控制的干扰。首先，根据量化的驾驶员分心程度和接管意图，建立驾驶员接管可行性框架。然后，基于线性参数变化车辆模型和非合作博弈论建立共享控制系统，以抑制时变速度和参数不确定性对共享控制的干扰。随后，结合驾驶员接管可行性和环境风险评估，构建了转向权限分配策略。所提出的基于 sigmoid 的映射函数确保了快速平稳的权限分配。最后，我们进行了一系列驾驶员在环实验，以验证我们提出的策略在各种驾驶场景下的有效性，结果表明，与其他先进的共享控制方案相比，我们的策略在减轻转向负担、提高驾驶安全性和增强车辆稳定性等方面具有更优越的性能。

Finally, a series of driver-in-the-loop experiments are conducted to validate the effectiveness of our proposed strategy across various driving scenarios, and the results demonstrate that our strategy has superior performance than other advanced shared control schemes in reducing steering burden, improving driving safety, and enhancing vehicle stability, etc.</div></div>","PeriodicalId":50630,"journal":{"name":"Computers & Electrical Engineering","volume":"120 ","pages":"Article 109753"},"PeriodicalIF":4.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441712","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}

The IoT has interconnected devices that collaborate via the Internet. Yet, its widespread connectivity and data generation pose cybersecurity risks. Integrating robust intrusion detection systems (IDSs) into the architecture has become crucial. IDSs safeguard data, detect attacks, and ensure network security and privacy. Constructing anomaly-based intrusion detection systems using artificial intelligence methods, often termed learning techniques, has gained significant traction lately. In this context, this study undertakes a systematic literature review to comprehensively analyze the current landscape of research concerning IoT security, explicitly employing learning techniques. These techniques fall under four primary categories: machine learning, deep learning, transfer learning, and federated learning. From a pool of 646 papers published between 2018 and 2023, we have selected 36 papers encompassing all these techniques based on the keywords of the study. These chosen studies were then categorized based on their respective learning techniques, with an additional hybrid classification that combines federated learning and transfer learning. Moreover, the paper provides a comparative analysis of the studied articles across different dimensions. The research outcomes demonstrate the effectiveness of each learning technique, shed light on the datasets and metrics employed, and conclude with a discussion on open challenges and future recommendations in this domain

To create a non-interrupted, economical and reliable direct current (DC) microgrid, multiple DC-DC converters can be connected in parallel. Current sharing among these multiple converters becomes essential for proper operation of the system. This study proposes an artificial neural network (ANN) based control technique for parallel connected DC-DC boost converters which ensures accurate current sharing according to the specified maximum limits. Levenberg-Marquardt algorithm-based ANN network is used to reduce the training time and, also to achieve near ≈ 100 % accuracy of the training data. ANN control provides better voltage regulation, accurate current sharing unlike the conventional proportional-integral (PI) based control which faces issues such as inaccurate current sharing, high transient, peak overshoots and steady state error during sudden change in the system. The efficient functioning of the proposed control method is verified by simulating two parallel connected DC-DC converters using MATLAB/Simulink. A hardware prototype of converters rating ≈ 250 W using TMS320F28379D Digital signal processor controller is also developed to verify the performance and effectiveness of the ANN based control in comparison to PI based technique. The ANN based technique is faster to achieve the reference voltage, and the peak overshoot is approximately 75 % lesser than the PI based control.

为了创建一个不间断、经济可靠的直流（DC）微电网，可以并联多个直流-直流转换器。这些多个转换器之间的电流共享对系统的正常运行至关重要。本研究针对并联的直流-直流升压转换器提出了一种基于人工神经网络（ANN）的控制技术，可确保按照指定的最大限制精确分流。基于 Levenberg-Marquardt 算法的 ANN 网络可缩短训练时间，并使训练数据的准确率接近 ≈ 100%。与传统的基于比例-积分（PI）的控制不同，ANN 控制可提供更好的电压调节和精确的电流分担，而传统的比例-积分（PI）控制则面临着电流分担不精确、瞬态高、峰值过冲以及系统突变时的稳态误差等问题。通过使用 MATLAB/Simulink 对两个并联的 DC-DC 转换器进行仿真，验证了所提出的控制方法的高效运作。此外，还使用 TMS320F28379D 数字信号处理器控制器开发了额定功率≈250 W 的转换器硬件原型，以验证基于 ANN 的控制与基于 PI 的技术相比的性能和有效性。基于 ANN 的技术实现参考电压的速度更快，峰值过冲比基于 PI 的控制少约 75%。
