Network failures, whether due to random disruptions or malicious attacks, pose significant challenges for unmanned aerial vehicle (UAV) swarm networks. One critical concern is determining which failed UAVs to recover or replace under limited resource conditions to enhance the robustness of their communication networks. Current research primarily considers static structural characteristics of the network and struggles to uncover deep features that influence network robustness, and the efficiency cannot meet the real-time needs in UAV swarm scenarios. To address these issues, we introduce a Prioritized recovery strategy for failed nodes based on Graph reinforcement Learning (PrGrL). This approach integrates a random SAmpling neighbor method with a multi-head attention mechanism to create a novel Graph Convolutional Kernel (SAGCK). This kernel is designed to extract global structural information and relative positional information of nodes within the graph. Additionally, we develop a deep Policy Network (dPN) that explores the intricate relationships between graph-level and node embedding features, enabling the assessment of nodes’ impact on overall robustness. PrGrL’s network parameters are automatically updated and optimized using scalable deep reinforcement learning. Importantly, PrGrL prioritizes the recovery of boundary nodes within connected components to enhance network robustness further. Our experiments, conducted on both simulated and real-world networks, demonstrate that PrGrL outperforms existing methods of robustness enhancement across various recovery ratios, attack strategies, and network sizes while delivering superior real-time performance. © 2014 IEEE.

As a next-generation mobile communication technology, 5G's network functions—cloudification, virtualization, and other characteristics enable the network to overcome single-point resource constraints and be deployed flexibly. However, it also exposes more attack surface interfaces to malicious users, who can launch high-traffic ddoS attacks that can seriously affect the resilience of network services. The complexity and dynamics of the 5G system itself make it difficult to capture and measure its resilience. In order to address the aforementioned issues, in this paper, we use Petri Nets to model 5G network systems deployed based on virtualization and implement different resilient resource scheduling strategies to mitigate and assess the impact of attack threats on the overall system resilience. By comparing the resilience gains of different resource scheduling strategies in the face of anomalous ddoS attacks, it is effectively demonstrated that the adoption of appropriate resilient resource scheduling strategies is instructive in reducing the traffic loss caused by ddoS attacks. © 2024, The Authors.

research on a Synchronization Algorithm of Look-Up Table in Open reconfigurable router

Chinese Journal of Electronics 2023年第3期19卷 419-422页

reconfigurable router with fast look-up table synchronization mechanism is necessary for Next generation network (NGN), which facilitates open and fast deployment of new services. Based on an open architecture, standard and highly credible interfaces among modules, a synchronization mechanism of the routing table and FIB (Forwarding information base) is put forward in this paper which is applicable to other look-up tables. This synchronization mechanism overcomes the inconsistency of look-up tables brought by the dynamic loading or unloading of forwarding planes. Anomalies can be rapidly discovered and eliminated by adding the appropriate synchronization messages to multi-queue, calculating the 16-bit Checksum in look-up table and resending parts of look-up table entries to the forwarding planes. A reconfigurable router prototype is built to simulate the scene. The results show that the proposed algorithm can realize high consistency and quick recovery in look-up tables, which improve stability and reliability of the reconfigurable router.

Although the perimeter security model works well enough when all internal hosts are credible, it is becoming increasingly difficult to enforce as companies adopt mobile and cloud technologies, i.e., the rise of bring your own device(BYOd). It is observed that advanced targeted cyber-attacks usually follow a cyber kill chain;for instance, advanced targeted attacks often rely on network scanning techniques to gather information about potential targets. In response to this attack method, we propose a novel approach, i.e., an "isolating and dynamic"cyber defense, which cuts these potential chains to reduce the cumulative availability of the gathered ***, we build a zero-trust network environment through network isolation, and then multiple network properties are maneuvered so that the host characteristics and locations needed to identify vulnerabilities cannot be ***, we propose a software-defined proactive cyber defense solution(SPd) for enterprise networks and design a general framework to strategically maneuver the IP address, network port, domain name, and path, while limiting the performance impact on the benign network user. Third, we implement our SPd proof-of-concept system over a software-defined network controller(Opendaylight). Finally, we build an experimental platform to verify the system's ability to prevent scanning, eavesdropping, and denial-of-service attacks. The results suggest that our system can significantly reduce the availability of network reconnaissance scan information, block network eavesdropping, and sharply increase the cost of cyber-attacks.

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.

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.

Word-level information is crucial for Chinese named entity recognition. Presently, most works have achieved better performance by extracting word-level information into character-level representations through existing lexicons, but the maintenance of lexical lists is a major challenge. In this paper, we present the NIMSI model, proposing the incorporation of multiple segmentation information to enhance recognition, using a trilogy to align character-level attention with word-level attention to construct features of segmented information in Chinese text. Also, we use a simple but effective method to directly incorporate multi-segmentation information into character-level representations. Finally, as the experiments on the three benchmark datasets show, our model effectively incorporates segmentation information and alleviates the segmentation errors.
