Network Function Virtualization (NFV) is proposed as new technology to address massive proprietary devices, high operation costs, poor flexibility and other problems in current traditional network. By separating network functions and proprietary devices, NFV can significantly reduce operation costs and enable flexible configuration of services, etc. Now NFV is widely used in various fields. However, due to virtualization and softwareization and other technical characteristics, NFV faces more serious security threats compared to traditional networks. This paper focuses on analyzing the NFV security threats under the new technology and summarizes them according to the causes of security threats. Subsequently, based on the results of the analysis, we propose the corresponding safety practice solutions. Finally, we prospect the research directions for improving NFV security. © 2023 IEEE.

To satisfy the service-side requirements for network layer authentication and traceability of users, this paper proposes a method for mobile terminal authentication and identity tracing based on IPv6 and blockchain. Our method introduces a new verification function (VEF) to verify the interface identification between the terminal and the 5G core network (5GC), thereby effectively enhancing the security of terminal access. Furthermore, considering the privacy protection of user identity information to prevent attackers from deducing encrypted content, it is necessary to periodically update encryption keys. Focusing on the practical deployment of VEFs on a network-wide scale and server-proximal for authentication and traceability, a time-varying key sharing scheme based on blockchain is proposed. The experimental section analyzes the communication performance and security of the proposed scheme, showing that our scheme does not significantly degrade the original network performance while providing substantial security gains. © 2024 IEEE.

Many networks in the real world are dynamically changing over time, and the community structure also changes accordingly. The community detection in the dynamic and constantly evolving network has received great attention from researchers. In order to uncover the community structure in the dynamic network, this paper proposes an incremental dynamic community detection algorithm based on node participation (NPICd). It defines the node participation to the community and the community fitness. In response to the changes of nodes and edges in the network, different update strategies are proposed to discover the community at different moments in an incremental manner. The experimental results on the real network show that compared with several widely used methods, our algorithm can quickly and accurately mine the community structure in the dynamic network. © 2021 IEEE.

Most existing multimodal named entity recognition (MNEr) methods cannot align image and text well, and fail to effectively fuse image-text semantic information, leading to suboptimal MNEr accuracy. To this end, this paper proposes a novel named entity recognition model based on Contrastive Learning and Multimodal Semantic Interaction (named CLMSI). Specifically, to narrow the semantic gap between image-text modalities, making semantically similar image-text representations closer and pushing dissimilar ones further apart, we propose a contrastive learning-based cross-modal alignment method. Moreover, to integrate multimodal information effectively and filter out the noise introduced by image features as thoroughly as possible, we propose to incorporate image descriptions as additional features to enrich the multimodal representation and to reduce the semantic bias of the image information. Extensive experiments conducted on two MNEr benchmark datasets, Twitter-2015 and Twitter-2017, demonstrate the superiority of the proposed method. Further ablation studies and case analyses also affirm the efficacy of CLMSI. © 2024 IEEE.

Cross-Site Scripting (XSS) vulnerabilities continue to pose a formidable challenge in the realm of web application security due to their prevalence. despite the development of various defense mechanisms, including input validation techniques and code differentiation strategies, these solutions have struggled to achieve broad adoption in real-world environments due to persistent issues such as unreliable detection, high computational overhead, scalability limitations, and compatibility concerns. This paper introduces a novel managed proxy-based framework for XSS defense, positioned strategically between the web browser and the web server. This framework employs a tag-based XSS protection mechanism alongside a defense-in-depth strategy, providing robust protection not only against XSS attacks but also against other web threats. Furthermore, the framework integrates advanced web front-end hardening techniques to significantly complicate the exploitation of potential vulnerabilities. Comprehensive practical evaluations indicate that the proposed framework is both flexible and effective, demonstrating outstanding performance across multiple dimensions.

Chinese Journal of Electronics 2025年第3期23卷 574-578页

Network virtualization has been a particularly important driving force behind the development of NGN. Finding effective ways to control self-adapting virtual networks has become a research hot spot. This paper tries to find an efficient way in combining dynamic resource sensing with traffic character and requirements in virtual network, based on that an intelligent cognition based virtual network resources management model has been put forward. We design a network topology view by coloring network topology matrix with current resources model. We present an intelligent virtual resource management mechanism based on the proposed network topology view. Experiment results illustrate that the proposed mechanism can improve VN capacity by automatic resource adjust-ment, which can obtain high utilization of VN resources without increasing computational expenses.
