—With the rapid development of technology and the acceleration of digitalisation, the frequency and complexity of cyber security threats are increasing. Traditional cybersecurity approaches, often based on static rules and predefined scenarios, are struggling to adapt to the rapidly evolving nature of modern cyberattacks. There is an urgent need for more adaptive and intelligent defence strategies. The emergence of Large Language Model (LLM) provides an innovative solution to cope with the increasingly severe cyber threats, and its potential in analysing complex attack patterns, predicting threats and assisting real-time response has attracted a lot of attention in the field of cybersecurity, and exploring how to effectively use LLM to defend against cyberattacks has become a hot topic in the current research field. This survey examines the applications of LLM from the perspective of the cyber attack lifecycle, focusing on the three phases of defense reconnaissance, foothold establishment, and lateral movement, and it analyzes the potential of LLMs in Cyber Threat Intelligence (CTI) tasks. Meanwhile, we investigate how LLM-based security solutions are deployed and applied in different network scenarios. It also summarizes the internal and external risk issues faced by LLM during its application. Finally, this survey also points out the facing risk issues and possible future research directions in this domain. Copyright © 2025, The Authors. All rights reserved.

IEEE Asia-Pacific Conference on Services Computing (APSCC)

作者： Rong Gang Bai Yu Gui Qu Yang Guo Bao Hua Zhao Department of Electronic Engineering and Information Science University of Science and Technology Hefei Anhui China Department of Computer Science Anhui Province Key Laboratory of Software in Computing and Communication University of Science and Technology Hefei Anhui China

This paper proposes an energy-efficient and collision-free medium access control protocol TDMA-WSN for wireless sensor networks. The protocol is based on time division multiple access (TDMA) principle and reduces energy consumption by avoiding overhearing, collision and idle listening. Nodes in TDMA-WSN build schedules based on information about their neighborhood to determine when they can transmit to their neighbors and when they should listen to the channel or sleep. TDMA-WSN proposes a novel resolution with three-d-hop neighborhood information to avoid collision caused by the two-hop collision-free principle used in some protocols. TDMA-WSN can accelerate passing message by arranging schedule based on routing information from the upper-layer. The simulation results indicate that TDMA-WSN outperforms contention-based protocols (e.g., S-MAC) and scheduling-based protocols (e.g., NAMA) with significant energy savings.

All kinds of intelligent terminal equipment emerge in endlessly and grow explosively. Typical devices, such as smartphones and tablets, are becoming more and more popular, furthermore, intelligent equipment market share has more than that on PCs. And on mobile devices area, the demand for virtualization technology is gradually increasing. As an important branch of computer technology development, operating system level virtualization is becoming a hot spot of current research due to its low overhead and the advantages of lightweight. In this paper, based on the Android system on mobile devices, implement a prototype which can run multiple virtual system instances on only an Android OS by modifying the namespace mechanism in the Linux kernel to and expand into driver namespace mechanism. In addition, put forward a model called the active-inactive model guaranteeing the process if and only if in the active namespace to operate the device drivers, which was designed and implemented a new scheme of operating system level virtualization.

There are many dynamic optimization problems in real-world applications. Although many variants of evolutionary algorithms and swarm intelligence have been proposed to solve such problems, little work has been conducted to address the dynamic constrained multimodal optimization problems (DCMMOPs). In DCMMOPs, there exist multiple optimal solutions corresponding to each environment that the algorithm is required to find. Sometimes, it is also necessary to identify the accepted local optima. Therefore, for each environment, the decision maker can select one from among multiple returned solutions according to his/her domain knowledge and/or preferences. The objective of this paper is to test the performance of various combinations of several population-based dynamic multimodal optimization algorithms and popular constraint handling techniques. First, the typical dynamic constrained optimization problems are slightly modified to be in the form of the dynamic constrained multimodal optimization problems. Second, four different population-based dynamic multimodal optimization algorithms, and five different constraint handling techniques, are pairwise tested in the experiments. Experimental results demonstrate that, among the candidates, DCMM-CSA-SR performs most successfully at all accuracy levels.

By researching Voronoi diagram, parallel algorithm, and divide-and-conquer method, we present a special data structure(change doubly-connected list little) for Voronoi diagram generation in parallel. In this paper we also present two proposal, they are one processor gradually to merge and 22-merger on the parallel machine, the experiment results show that the present algorithm runs faster than the serial program. By analyzing the various results, we should choose the most suitable number of processors according to the point set scale. At last, we can conclude that gradually merger with one processor is better proposal for Voronoi diagram parallel generation.

Extended Doo-Sabin surfaces

In this paper we propose a modification of quadratic NURSSes called EDSes (Extended Doo-Sabin Surfaces). EDSes inherit the refinement rules for quadratic NURSSes for four-sided faces but use the refinement rules for Doo-Sabin surfaces for faces with other than four sides. Compared to quadratic NURSSes, if all the knot intervals are positive, EDSes always converge to G1 continuous limit surfaces with closed-form limit point as well as limit normal rules. 1548-7741/Copyright © 2011 Binary Information Press.

Cloud-based expression recognition from high-resolution facial images may put the subjects’ privacy at risk. We identify two kinds of privacy leakage, the appearance leakage in which the visual appearances of subjects are disclosed and the identity-pattern leakage in which the identity information of subjects is dug out. To address both leakages, we propose privacy-protected facial expression recognition from low-resolution facial images with the help of high-resolution facial images. Specifically, to prevent appearance leakage, we propose to extract identity-invariant representations from downsampled images, from which the visually distinguishable appearances cannot be recovered. To prevent identity-pattern leakage, we propose to eliminate the identity information from the extracted representations by leveraging the disentangled representations of high-resolution images as privileged information. After training, our method can fully capture identity-invariant representations from downsampled images for expression recognition without the requirement of high-resolution samples. These privacy-protected representations can be safely transmitted through the Internet. Experimental results in different scenarios demonstrate that the proposed method protects privacy without significantly inhibiting facial expression recognition.

In the wireless network of finite spectrum resource, some communication users probably do not allocate the spectrum so that their communication should be delayed. Thus it is necessary to arrange the communication time of the systems when we allocate the communication frequency. We construct a frequency-time spectrum model and propose a joint pre-allocation in a two-dimension space. Through the distributed games learning algorithm, each system could obtain its communication schedule, which makes the bandwidth utilization achieve a quite high level and arranges the global communication time as short as possible. The experiments show that our results have obvious superiorities in both bandwidth utilization and temporal performance relative to other allocation algorithms.

Physical properties of the chaotic system play important roles on studying the innate character and deciding the practical predictability of the dynamics. For a short piece of undersampled chaotic signals, it is very hard to abstract the physical properties of the signal source from the sequence. In this paper, we model this type of data with global S-NURBS method to reconstruct a smooth trajectory and resample the trajectory to get enough series. In this way, the problem of estimating the physical properties from small undersampled data is turned to the work of calculating the properties of the resampled time series. The new interpolation method is named as S-NURBS resampling method, and the simulation experiment demonstrates that the new method has a good performance in studying physical systems from the observed time series.

A hybrid active contour model with local Gaussian distribution fitting energy for image segmentation

Journal of Information and Computational Science 2015年第17期12卷 6515-6523页

Active contour models have been widely applied in image segmentation with promising results. However, many of them fail to segment images successfully due to intensity inhomogeneity. To address this problem, we propose a hybrid region-based active contour model which fully utilizes local intensity information. This model develops a localized active contour framework and incorporates a local Gaussian distribution fitting energy. In order to increase both the computational efficiency and stability of the proposed model, a multi-resolution strategy is employed and the active contour is evolved in a reinitialization-free way. Extensive experiments demonstrate that our model is effective and efficient in segmenting images with intensity inhomogeneity, and outperforms several state-of-the-art algorithms. © 2015 by Binary Information Press.
