摘要 ：
In blockchain technology, data are stored on decentralized nodes and public to each node in the blockchain network. Hence, the focus of privacy protection in the blockchain guarantees the anonymity of transactions such that attackers cannot attain the users' personal information through data analysis. Among the existing privacy protection technologies, the scheme based on group signature has good anonymity, but the existing scheme exists a large number of operations that are difficult to apply to wireless terminals. In this paper, using the powerful offloading capability of edge computing, we propose a blockchain node traceable identity privacy technology scheme based on threshold group signature, and the scheme greatly reduces the computing burden of nodes while achieving node privacy protection.

摘要 ：
The encryption and signature schemes based on traditional public key are no longer applicable for devices with limited hardware and software resources in the Internet of Things (IoT), since those schemes consume too much hardware and software. To ensure the security and efficiency of data transmission, we construct a secure and lightweight certificateless hybrid signcryption scheme for Compared with the existing schemes, this scheme only needs one bilinear calculation for one communication, which is computationally efficient for protecting the secure communication between nodes with limited resources in IoT. To meet the security requirements of the complex IoT, based on difficult problem assumption of bilinear pairings, this scheme can simultaneously meet security requirements of the IoT such as confidentiality, unforgability, semipublic verification, forward security known session-specific temporary information security. In addition, we prove the security and correctness of this scheme in Random Oracle Model (ROM). (C) 2021 Elsevier B.V. All rights reserved.

In this article, we consider the transmission wave/plate equation with variable coefficients on R-n(n >= 3). By virtue of the Morawetz multipliers in non Euclidean geometries and compactness-uniqueness arguments, we obtain some stability result of the transmission wave/plate system under suitable geometric conditions.

摘要 ：
Trusted date collection is the precondition of the security of Internet of Things (IOT). Recently, compressed sensing technology, which can enable the reduction of the energy consumption and time delay of data collection, has been extensively studied in IOT; However, the security of compressed sensing technology in IOT has not been sufficiently considered. Since compressed sensing depends the cooperation between IOT nodes and then sensing data is transparent for all IOT nodes, which is subjected to malicious nodes attack. Therefore, we propose a trusted data collection scheme based on compressed sensing oriented to the IOT. When data collection is tampered with, the scheme can detect malicious nodes. Experiments demonstrate that the proposed scheme can ensure data security with a low energy consumption. © 2021 John Wiley & Sons, Ltd.

摘要 ：
本发明提供一种基于卷积神经网络的加密流量实时分类方法及装置，该方法包括：在每一条加密流量中采样预设数量的数据包；将采样得到的数据包作为字节流，任意相连两个字节作为一个字节对，并确定所有字节对的频率特征；将所有字节对的频率特征，输入预训练的卷积神经网络模型，输出每一条加密流量的数据流类型。该方法对加密流量的原始字节信息采用基于频率特征的表示，而非原始字节直接构造输入特征，从而使卷积神经网络的学习效果加强，分类准确度更高。此外，采样的数据包数量可以根据实际流量捕获情况调整，而不需要重新设计网络模型的结构，具有更好的适用性。由于采用了字节对的频率特征，从而分类所需数据包少，有利于数据分类的实时性。

摘要 ：
With the development of information technology, the Internet of Things terminals are vulnerable to threats such as eavesdropping, tampering, and counterfeiting. The application of threshold group signature technology can effectively ensure the security of the system in applications such as battlefield intelligent decision-making, connected vehicles, and intelligent manufacturing. However, the existing threshold group signature schemes lack the two-way trusted authentication mechanism between group members and group manager, and group manager can easily become a security risk for the entire signature system. To solve this problem, this paper proposes a threshold group signature scheme based on elliptic curve that achieves mutual authentication of group members and group manager. The security analysis proves that the proposed scheme is anonymous, traceable, and can resist collusion attacks and frame attacks. The results of performance analysis and comparison also show that under the same security strength, the scheme proposed has shorter signature length, lower calculation amount for signature generation and signature verification, which can effectively reduce the communication and calculation overhead of the IoT terminal, and can be better applied to the Internet of Things application scenarios.

摘要 ：
Accurate prediction of the trust relationship is the basis for trusted access and secure interaction between Internet of things nodes. To evaluate the degree of trust, a trust metric is assigned to every node depending on its several attributes. Normal nodes in Internet of things tend to suffer collusion attacks from malicious nodes; thus, the accuracy of the trust measurement decreases. To enhance the security of interaction between massive Internet of things nodes, we propose a multidimensional attribute trust model and a dynamic maintenance mechanism of a trusted group. The proposed model provides a reference for the selection and evaluation of node multidimensional attribute factors to adapt to different Internet of things application scenarios. The dispersion of satisfaction records is used to discover abnormal data and weaken its influence on the calculation of the node’s comprehensive trust evaluation. The construction of trusted groups provides an architectural foundation for the application of group signature that maintains low network overhead. The performance of multidimensional attribute trust model and dynamic maintenance mechanism is verified using Netlogo. Simulation results show the efficiency of the proposed model to classify the malicious nodes and honest nodes, as well as to build a trusted group that could ensure honest nodes occupy the major proportion. © The Author(s) 2021.

摘要 ：
Wireless sensor network is a key technology in Internet of Things. However, due to the large number of sensor nodes and limited security capability, aging nodes and malicious nodes increase. In order to detect the untrusted nodes in the network quickly and effectively and ensure the reliable operation of the network, this paper proposes a dynamic network security mechanism. Firstly, the direct trust value of the node is established based on its behavior in the regional information interaction. Then, the comprehensive trust value is calculated according to the trust recommendation value and energy evaluation value of other high-trust nodes. Finally, node reliability and management nodes are updated periodically. Malicious nodes are detected and isolated according to the credibility to ensure the dynamic, safe, and reliable operation of the network. Simulation results and analysis show that the node trust value calculated by this mechanism can reflect its credibility truly and accurately. In terms of reliable network operation, the mechanism can effectively detect malicious nodes, with higher detection rate, avoid the risk of malicious nodes as management nodes, reduce the energy consumption of nodes, and also play a defensive role in DOS attacks in wireless sensor networks. © 2021 Guiping Zheng et al.
