The research addresses energy consumption, latency, and network reliability challenges in wireless sensor network communication, especially in military security applications. A multi-agent context-aware model employing the belief-desire-intention (BDI) reasoning mechanism is proposed. This model utilizes a semantic knowledge-based intelligent reasoning network to monitor suspicious activities within a prohibited zone, generating alerts. Additionally, a BDI intelligent multi-level data transmission routing algorithm is proposed to optimize energy consumption constraints and enhance energy-awareness among nodes. The energy optimization analysis involves the Energy Percent Dataset, showcasing the efficiency of four wireless sensor network techniques (E-FEERP, GTEB, HHO-UCRA, EEIMWSN) in maintaining high energy levels. E-FEERP consistently exhibits superior energy efficiency (93 to 98%), emphasizing its effectiveness. The Energy Consumption Dataset provides insights into the joule measurements of energy consumption for each technique, highlighting their diverse energy efficiency characteristics. Latency measurements are presented for four techniques within a fixed transmission range of 5000 m. E-FEERP demonstrates latency ranging from 3.0 to 4.0 s, while multi-hop latency values range from 2.7 to 2.9 s. These values provide valuable insights into the performance characteristics of each technique under specified conditions. The Packet Delivery Ratio (PDR) dataset reveals the consistent performance of the techniques in maintaining successful packet delivery within the specified transmission range. E-FEERP achieves PDR values between 89.5 and 92.3%, demonstrating its reliability. The Packet Received Data further illustrates the efficiency of each technique in receiving transmitted packets. Moreover the network lifetime results show E-FEERP consistently improving from 2550 s to round 925. GTEB and HHO-UCRA exhibit fluctuations around 3100 and 3600 s, indicating variable performance. In contrast, EEIMWSN consistently improves from round 1250 to 4500 s.
该研究解决了无线传感器网络通信,特别是军事安全应用中的能耗、延迟和网络可靠性挑战。研究提出了一种采用信念-愿望-意图(BDI)推理机制的多代理情境感知模型。该模型利用基于语义知识的智能推理网络监控禁区内的可疑活动,并生成警报。此外,还提出了一种 BDI 智能多级数据传输路由算法,以优化能耗约束并增强节点间的能量感知。能量优化分析涉及能量百分比数据集,展示了四种无线传感器网络技术(E-FEERP、GTEB、HHO-UCRA、EEIMWSN)在保持高能量水平方面的效率。E-FEERP 始终表现出卓越的能源效率(93% 至 98%),凸显了其有效性。能耗数据集提供了每种技术的焦耳能耗测量数据,突出了它们不同的能效特性。E-FEERP 的延迟时间为 3.0 至 4.0 秒,而多跳延迟时间为 2.7 至 2.9 秒。数据包交付率 (PDR) 数据集显示,这些技术在指定传输范围内保持数据包成功交付的性能始终如一。E-FEERP 的 PDR 值介于 89.5% 和 92.3% 之间,证明了其可靠性。数据包接收数据进一步说明了每种技术在接收传输数据包方面的效率。此外,网络寿命结果显示,E-FEERP 从 2550 秒持续提高到 925 秒。GTEB 和 HHO-UCRA 在 3100 秒和 3600 秒左右出现波动,表明性能参差不齐。相比之下,EEIMWSN 从 1250 到 4500 秒持续改善。

Over the last 20 years, Wi-Fi technology has advanced to the point where most modern devices are small and rely on Wi-Fi to access the internet. Wi-Fi network security is severely questioned since there is no physical barrier separating a wireless network from a wired network, and the security procedures in place are defenseless against a wide range of threats. This study set out to assess federated learning, a new technique, as a possible remedy for privacy issues and the high expense of data collecting in network attack detection. To detect and identify cyber threats, especially in Wi-Fi networks, the research presents FEDDBN-IDS, a revolutionary intrusion detection system (IDS) that makes use of deep belief networks (DBNs) inside a federated deep learning (FDL) framework. Every device has a pre-trained DBN with stacking restricted Boltzmann machines (RBM) to learn low-dimensional characteristics from unlabelled local and private data. Later, these models are combined by a central server using federated learning (FL) to create a global model. The whole model is then enhanced by the central server with fully linked SoftMax layers to form a supervised neural network, which is then trained using publicly accessible labeled AWID datasets. Our federated technique produces a high degree of classification accuracy, ranging from 88% to 98%, according to the results of our studies.
在过去的 20 年里,Wi-Fi 技术已经发展到这样一个地步,即大多数现代设备都是小型的,依靠 Wi-Fi 接入互联网。由于无线网络与有线网络之间没有物理屏障,现有的安全程序无法抵御各种威胁,Wi-Fi 网络的安全性受到严重质疑。本研究旨在评估联合学习这种新技术,以解决网络攻击检测中的隐私问题和高昂的数据收集费用。为了检测和识别网络威胁,尤其是 Wi-Fi 网络中的网络威胁,该研究提出了 FEDDBN-IDS,这是一种革命性的入侵检测系统(IDS),在联合深度学习(FDL)框架内利用深度信念网络(DBN)。每台设备都有一个预先训练好的 DBN,通过堆叠受限玻尔兹曼机(RBM)从未标明的本地数据和私人数据中学习低维特征。随后,中央服务器使用联合学习(FL)将这些模型组合起来,创建一个全局模型。然后,中央服务器通过完全链接的 SoftMax 层对整个模型进行增强,形成一个监督神经网络,然后使用可公开访问的标记 AWID 数据集对其进行训练。根据我们的研究结果,我们的联合技术产生了很高的分类准确率,从 88% 到 98% 不等。

Recently, biometric recognition has become a significant field of research. The concept of cancelable biometrics (CB) has been introduced to address security concerns related to the handling of sensitive data. In this paper, we address unconstrained face verification by proposing a deep cancelable framework called BiometricNet+ that employs random projections (RP) to conceal face images and compressive sensing (CS) to reconstruct measurements in the original domain. Our lightweight design enforces the properties of unlinkability, revocability, and non-invertibility of the templates while preserving face recognition accuracy. We compare facial features by learning a regularized metric: at training time, we jointly learn facial features and the metric such that matching and non-matching pairs are mapped onto latent target distributions; then, for biometric verification, features are randomly projected via random matrices changed at every enrollment and query and reconstructed before the latent space mapping is computed. We assess the face recognition accuracy of our framework on challenging datasets such as LFW, CALFW, CPLFW, AgeDB, YTF, CFP, and RFW, showing notable improvements over state-of-the-art techniques while meeting the criteria for secure cancelable template design. Since our method requires no fine-tuning of the learned features, it can be applied to pre-trained networks to increase sensitive data protection.
最近,生物识别已成为一个重要的研究领域。可取消生物识别(CB)的概念已被引入,以解决与处理敏感数据有关的安全问题。在本文中,我们提出了一种名为 BiometricNet+ 的深度可取消框架,利用随机投影(RP)隐藏人脸图像,并利用压缩传感(CS)重建原始域中的测量值,从而解决无约束人脸验证问题。我们的轻量级设计在保持人脸识别准确性的同时,还强化了模板的不可链接性、可撤销性和不可逆转性。我们通过学习正则化度量来比较面部特征:在训练时,我们共同学习面部特征和度量,从而将匹配和非匹配对映射到潜在目标分布上;然后,在生物识别验证时,通过每次注册和查询时改变的随机矩阵随机投射特征,并在计算潜在空间映射之前进行重建。我们在具有挑战性的数据集(如 LFW、CALFW、CPLFW、AgeDB、YTF、CFP 和 RFW)上评估了我们的框架的人脸识别准确性,结果表明,与最先进的技术相比,我们的框架有显著的改进,同时符合安全可取消模板设计的标准。由于我们的方法不需要对学习到的特征进行微调,因此它可以应用于预训练网络,以加强敏感数据的保护。

With the rapid development of the Internet of Things and intelligent technology, the application of Radio Frequency Identification (RFID) technology in training room management is becoming increasingly widespread. An efficient and accurate RFID system can significantly improve the management efficiency and resource utilization of the training room, thereby improving teaching quality and reducing management costs. Although RFID technology has many advantages, there are still some problems in practical applications, such as label collision and recognition of unknown labels. These issues not only affect the performance of the system but may also cause interference with actual teaching and management. This study proposes a grouping-based bit arbitration query tree algorithm and anti-collision technology to solve label collisions and reduce label recognition time in the technology. A new unknown label recognition algorithm is also proposed to improve the recognition efficiency and accuracy of identifying new unknown labels. Related experiments have shown that the recognition accuracy of the algorithm designed this time is 95.86%. Compared with other algorithms, the number of idle time slots is the smallest. When the number of queries is 1000, the algorithm has 1842 queries, and the communication complexity is the best. When the number of unknown tags is 10,000, the actual accuracy rate is 95.642%. Compared with traditional recognition algorithms, the new unknown label recognition algorithm has a smaller frame length in the same label proportion and good recognition performance. On a theoretical level, the research content on RFID technology helps to improve and develop the basic theories of the Internet of Things and intelligent recognition technology and provides solutions and application technologies for equipment management and IoT applications in training rooms. On a practical level, the research results can provide specific guidance for the management of training rooms, help solve equipment management and safety maintenance problems in practical applications, and improve the management efficiency of training rooms.
随着物联网和智能技术的快速发展,射频识别(RFID)技术在实训室管理中的应用也越来越广泛。高效、准确的 RFID 系统能显著提高实训室的管理效率和资源利用率,从而提高教学质量,降低管理成本。虽然 RFID 技术有很多优点,但在实际应用中仍存在一些问题,如标签碰撞和未知标签的识别等。这些问题不仅会影响系统性能,还可能对实际教学和管理造成干扰。本研究提出了一种基于分组的位仲裁查询树算法和防碰撞技术,以解决该技术中的标签碰撞问题并缩短标签识别时间。同时,还提出了一种新的未知标签识别算法,以提高识别效率和识别新的未知标签的准确性。相关实验表明,本次设计的算法识别准确率为 95.86%。与其他算法相比,空闲时隙数最小。当查询次数为 1000 次时,该算法的查询次数为 1842 次,通信复杂度最好。当未知标签数量为 10,000 个时,实际准确率为 95.642%。与传统识别算法相比,新的未知标签识别算法在相同标签比例下,帧长较小,识别性能良好。在理论层面,RFID 技术的研究内容有助于完善和发展物联网和智能识别技术的基础理论,为实训室设备管理和物联网应用提供解决方案和应用技术。在实践层面,研究成果可为实训室管理提供具体指导,有助于解决实际应用中的设备管理和安全维护问题,提高实训室的管理效率。

With the development of Internet technology, the large number of network nodes and dynamic structure makes network security detection more complex, which requires the use of a multi-layer feedforward neural network to build a security threat detection model to improve network security protection. Therefore, the entropy model is adopted to optimize the particle swarm algorithm to decode particles, and then the single-peak and multi-peak functions are used to test and compare the particle entropy and fitness values to optimize the weights and thresholds in the multi-layer feedforward neural network. Finally, Suspicious Network Event Recognition Dataset discovered by data mining is sampled and applied to the entropy model particle swarm optimization for training. The test results show that there are four functions for the optimal mean and standard deviation in this algorithm, with values of 5.712e − 02, 4.805e − 02, 4.914e − 01, 1.066e − 01, 1.577e − 01, 1.343e − 01, and 2.089e + 01, 5.926, respectively. Overall, the algorithm proposed in the study is the best. Finally, the detection rate of attack types is calculated. The multi-layer feedforward neural network algorithm is 83.80%, the particle swarm optimization neural network algorithm is 91.00%, and the entropy model particle swarm optimization algorithm is 95.00%. The experiment shows that the research model has high accuracy in detecting network security threats, which can provide technical support and theoretical assistance for network security protection.

In recent years, various smart devices based on IoT technology, such as smart homes, healthcare, detection, and logistics systems, have emerged. However, as the number of IoT-connected devices increases, securing the IoT is becoming increasingly challenging. To tackle the increasing security challenges caused by the proliferation of IoT devices, this research proposes an innovative method for IoT identity authentication. The method is based on an improved ring-learning with errors (R-LWE) algorithm, which encrypts and decrypts communication between devices and servers effectively using polynomial modular multiplication and modular addition operations. The main innovation of this study is the improvement of the traditional R-LWE algorithm, enhancing its efficiency and security. Experimental results demonstrated that, when compared to number theory-based algorithms and elliptic curve cryptography algorithms at a 256-bit security level, the enhanced algorithm achieves significant advantages. The improved algorithm encrypted 20 data points with an average runtime of only 3.6 ms, compared to 7.3 ms and 7.7 ms for the other algorithms. Similarly, decrypting the same amount of data had an average runtime of 2.9 ms, as opposed to 7.3 ms and 8 ms for the other algorithms. Additionally, the improved R-LWE algorithm had significant advantages in terms of communication and storage costs. Compared to the number theory-based algorithm, the R-LWE algorithm reduced communication and storage costs by 3 °C each, and compared to elliptic curve cryptography, it reduced them by 4 °C each. This achievement not only enhances the efficiency of encryption and decryption but also lowers the overall operational costs of the algorithm. The research has made significant strides in improving the security and efficiency of IoT device identity authentication by enhancing the R-LWE algorithm.

However, as the number of IoT-connected devices increases, securing the IoT is becoming increasingly challenging. To tackle the increasing security challenges caused by the proliferation of IoT devices, this research proposes an innovative method for IoT identity authentication. The method is based on an improved ring-learning with errors (R-LWE) algorithm, which encrypts and decrypts communication between devices and servers effectively using polynomial modular multiplication and modular addition operations. The main innovation of this study is the improvement of the traditional R-LWE algorithm, enhancing its efficiency and security. Experimental results demonstrated that, when compared to number theory-based algorithms and elliptic curve cryptography algorithms at a 256-bit security level, the enhanced algorithm achieves significant advantages. The improved algorithm encrypted 20 data points with an average runtime of only 3.6 ms, compared to 7.3 ms and 7.7 ms for the other algorithms. Similarly, decrypting the same amount of data had an average runtime of 2.9 ms, as opposed to 7.3 ms and 8 ms for the other algorithms. Additionally, the improved R-LWE algorithm had significant advantages in terms of communication and storage costs. Compared to the number theory-based algorithm, the R-LWE algorithm reduced communication and storage costs by 3 °C each, and compared to elliptic curve cryptography, it reduced them by 4 °C each. This achievement not only enhances the efficiency of encryption and decryption but also lowers the overall operational costs of the algorithm. The research has made significant strides in improving the security and efficiency of IoT device identity authentication by enhancing the R-LWE algorithm.

The development of big data has epromoted the development of Internet technology, but it has brought more network security and privacy problems. Therefore, how to solve network security problems is the main research direction of current network technology development. In order to deal with the harm of network attacks to personal privacy security, this paper studies and proposes an RFID mutual authentication protocol against exhaustive attacks based on improved Hash function, and proposes a security proof based on BAN logic rules. At the same time, to enhance the computing resources of the improved protocol, this paper proposes an improved authentication query protocol for multi-source RFID tags. In the performance analysis, when the distance between the reader and the tag reaches 10 m, the improved protocol can still be higher than 90%. The application test shows that the improved protocol proposed in the study is capable of resisting exhaustive attacks, its execution time is short, and it is less affected by the number of tags. The above results show that in the context of big data, the improved RFID mutual authentication protocol proposed by the research against network exhaustive attacks has a more significant defense effect, can effectively protect user privacy, and has a greater reference value in network security research.

Personalized medical data privacy and secure storage protection face serious challenges, especially in terms of data security and storage efficiency. Traditional encryption and storage solutions cannot meet the needs of modern medical data protection, which has led to an urgent need for new data protection strategies. Research personalized medical data privacy and secure storage protection based on hybrid encryption, in order to improve the security and efficiency of data storage. A hybrid encryption mechanism was proposed, which uses user attributes as keys for data encryption. The results show that the storage consumption of user attribute keys increases with the number of user attributes, but the consumption of hybrid encryption privacy storage technology is much smaller than that of traditional schemes. In the test, when the number of users increased to 30, the processing time first reached 1200 ms. During the increase in data volume, both test data and real data showed a brief decrease in attack frequency, but after the data volume reached 730–780, the attack frequency increased. It is worth noting that the performance of test data is better than that of real data. Personalized medical data privacy and secure storage protection based on hybrid encryption can not only effectively improve data security and reduce the risk of attack, but also greatly outperform traditional solutions in storage consumption and processing time. It has important practical significance for modern medical data storage protection.

Extensive research has been conducted to enhance the availability of IoT devices and data by focusing on the rapid prediction of instantaneous fault rates and temperatures. Temperature plays a crucial role in device availability as it significantly impacts equipment performance and lifespan. It serves as a vital indicator for predicting equipment failure and enables the improvement of availability and efficiency through effective temperature management. In the proposed optimization scheme for IoT device and data availability, the artificial neural network (ANN) algorithm and the K-Nearest Neighbours (KNN) algorithm are utilized to drive a neural network. The preliminary algorithm for availability optimization is chosen, and the target is divided into two parts: data optimization and equipment optimization. Suitable models are constructed for each part, and the KNN-driven neural network algorithm is employed to solve the proposed optimization model. The effectiveness of the proposed scheme is clearly demonstrated by the verification results. When compared to the benchmark method, the availability forward fault-tolerant method, and the heuristic optimization algorithm, the maximum temperature was successfully reduced to 2.0750 °C. Moreover, significant enhancements in the average availability of IoT devices were achieved, with improvements of 27.03%, 15.76%, and 10.85% respectively compared to the aforementioned methods. The instantaneous failure rates were 100%, 87.89%, and 84.4% respectively for the three algorithms. This optimization algorithm proves highly efficient in eliminating fault signals and optimizing the prediction of time-limited satisfaction. Furthermore, it exhibits strategic foresight in the decision-making process.

Wireless sensor networks, as an emerging information exchange technology, have been widely applied in many fields. However, nodes tend to become damaged in harsh and complex environmental conditions. In order to effectively diagnose node faults, a Bayesian model-based node fault diagnosis model was proposed. Firstly, a comprehensive analysis was conducted into the operative principles of wireless sensor systems, whereby fault-related features were then extrapolated. A Bayesian diagnostic model was constructed using the maximum likelihood method with sufficient sample features, and a joint tree model was introduced for node diagnosis. Due to the insufficient accuracy of Bayesian models in processing small sample data, a constrained maximum entropy method was proposed as the prediction module of the model. The use of small sample data to obtain the initial model parameters leads to improved performance and accuracy of the model. During parameter learning tests, the limited maximum entropy model outperformed the other two learning models on a smaller dataset of 35 with a distance value of 2.65. In node fault diagnosis, the diagnostic time of the three models was compared, and the average diagnostic time of the proposed diagnostic model was 41.2 seconds. In the node diagnosis accuracy test, the proposed model has the highest node fault diagnosis accuracy, with an average diagnosis accuracy of 0.946, which is superior to the other two models. In summary, the node fault diagnosis model based on Bayesian model proposed in this study has important research significance and practical application value in wireless sensor networks. By improving the reliability and maintenance efficiency of the network, this model provides strong support for the development and application of wireless sensor networks.
无线传感器网络作为一种新兴的信息交换技术,在许多领域得到了广泛的应用。然而,在恶劣复杂的环境条件下,节点容易受到损伤。为了有效诊断节点故障,提出了一种基于贝叶斯模型的节点故障诊断模型。首先,对无线传感器系统的工作原理进行了全面的分析,并在此基础上推断出故障相关特征。利用充分样本特征的极大似然法构建贝叶斯诊断模型,并引入联合树模型进行节点诊断。针对贝叶斯模型在处理小样本数据时精度不足的问题,提出了约束最大熵法作为贝叶斯模型的预测模块。利用小样本数据获取初始模型参数,提高了模型的性能和精度。在参数学习测试中,有限最大熵模型在较小的35个数据集上以2.65的距离值优于其他两种学习模型。在节点故障诊断中,比较了三种模型的诊断时间,提出的诊断模型的平均诊断时间为41.2秒。在节点诊断准确率测试中,该模型的节点故障诊断准确率最高,平均诊断准确率为0.946,优于其他两种模型。综上所述,本文提出的基于贝叶斯模型的节点故障诊断模型在无线传感器网络中具有重要的研究意义和实际应用价值。通过提高网络的可靠性和维护效率,该模型为无线传感器网络的发展和应用提供了有力的支持。
