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The encryption and signature schemes based on traditional public key are no longer applicable for devices with limited hardware and software resources in the Internet of Things (IoT), since those schemes consume too much hardware and software.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 ：
To solve the real-time trusted measurement of user behaviour in trusted networks, a new combination of dynamic and static, subjective and objective behaviour trusted measurement scheme is presented. The scheme analyses the credibility of the real-time user state and the direct trusted measurement value of the user behaviour, and finally controls the user behaviour by the feedback measurement of the user behaviour. The research results show that when the ratio of untrusted nodes is 15%, 30% and 50%, the trusted detection rate of this paper can reach more than 92%, and the untrusted node in trusted network can be identified with the increase of time. Compared with traditional measurement scheme, the scheme can be more accurate and reasonable to calculate the credibility of user behaviour, and can reflect the changes of the credibility of users’ actual behaviour at all times, and ultimately implement the feedback control on user behaviour.

摘要 ：
In the field of applied IoT, a large number of wireless sensor devices are tasked with data production and collection, providing IoT subjects with a large amount of basic data to support top-level IoT applications. However, there is a considerable risk of being attacked on such sensor networks that are organized in a wireless form. These relatively independent network devices have extremely limited performance and lifetime, a problem that can be supplemented in a centralized network with base stations by relying on the performance of the core nodes of the network, but in a decentralized self-organizing network, they can have a serious adverse impact on the implementation of security solutions. Considering the fundamental nature of the data generated by such end devices in IoT application services, the protection of their security is also directly related to the quality of upper layer services provided. The main research result of this paper is the design of a trust routing scheme for self-organizing networks. The scheme is based on a comprehensive evaluation of data transmission rate, transmission delay, and other factors related to the operation status of the self-organized network and improves the efficiency of the overall work of the self-organized network by reducing the performance consumption of individual nodes of the self-organized network and balancing the network load. © 2021 Bei Gong et al.

摘要 ：
Multi-agent decision making is a fundamental problem in edge intelligence. In this paper, we study this problem for IoT networks under the distributed Multi-Armed Bandits (MAB) model. Most of existing works for distributed MAB demand long-time stable networks connected by powerful devices and hence may not be suitable for mobile IoT networks with harsh IoT constraints. To meet the challenge of resource constraints in mobile IoT environment, we propose a lightweight and robust learning algorithm in a dynamic network allowing topology changes. In our model, each agent is assumed to have only limited memory and communicate with each other asynchronously. Moreover, we assume that the bandwidth for exchanging information is limited and each agent can transmit O(log2K) bits (K denotes the number of arms) per communication. Rigorous analysis shows that despite these harsh constraints, the best arm/option can be identified collaboratively by the agents and the algorithm converges efficiently. Extensive experiments illustrate that the proposed algorithm exhibits good efficiency and stability in mobile settings. © 2020
