With the rapid development of Internet and the expanding application fields of network applications, it is not enough to maintain the network security only depend on those professional network technical administrators. In this paper a novel visualization tool based on treemap, which is called NetVis, is introduced to bind the network security technique and general network management together in an integrated visualization. NetVis is designed in 2D view. The experiments show that NetVis can not only detect the abnormal activities in the network, but also make the network management more intuitive and efficient

Rule of minimum fractal dimension for GPR ground bounce removal

Yi Qi Yi Biao Xue Bao/Chinese Journal of Scientific Instrument 2010年第8 SUPPL.期31卷 123-127页

For the problem of the imprecise estimation of the reference of GPR ground bounce wave and relying on a priori knowledge, the criteria on minimum fractal dimension is introduced to select the reference to the ground bounce wave automatically. First, the detection direction of the fractal dimension curve is achieved by the the box-counting dimension of A-scan for a given ground-penetrating radar B-scan. Compared with the fractal dimension of the average trace of the B-scan, the trace of minimum fractal dimension or the trace which is averaged by the traces whose fractal dimension is less than the one of average trace, is selected as the reference ground bounce wave. Experimental results show that the method can preserve more energy of probable target area and more effective than the one of average trace.

Image Retrieval Approach Based on Intuitive Fuzzy Set Combined with Genetic Algorithm

引用

Journal of Beijing Institute of technology 2009年第1期18卷 60-64页

作者：王潇茵徐卫华胡昌振 Lab of Computer Network Defense Technology Beijing Institute of Technology Automation Station of Army Aviation Department of the General Staff

Aiming at shortcomings of traditional image retrieval systems, a new image retrieval approach based on color features of image combining intuitive fuzzy theory with genetic algorithm is proposed. Each image is segmented into a constant number of sub-images in vertical direction. Color features are extracted from every sub-image to get chromosome coding. It is considered that fuzzy membership and intuitive fuzzy hesitancy degree of every pixel＇s color in image are associated to all the color histogram bins. Certain feature, fuzzy feature and intuitive fuzzy feature of colors in an image, are used together to describe the content of image. Efficient combinations of sub-image are selected according to operation of selecting, crossing and variation. Retrieval results are obtained from image matching based on these color feature combinations of sub-images. Tests show that this approach can improve the accuracy of image retrieval in the case of not decreasing the speed of image retrieval. Its mean precision is above 80 %.

the research proposed an approach that based on Domain Partitional Markov Decision Process to make decisions about the protection and defense against cyber attacks. We partitioned the network into several security domains. Markov decision models were made in each domain, with each state established by situational awareness. Strategy sets were set according to the system states. Cost-benefit factors were considered comprehensively to calculate the rewards of counter-measures. On one hand, domain partition overcame the deficiency of control granularit;on the other hand the payoffs of the counter-measures were calculated comprehensively. The experimental results show that the model can effectively improve the accuracy and effectiveness of network defense. ©2009 IEEE.

The nude image is an important part in adult images spreading on the Internet. A new recognizing algorithm of nude image based on the navel and body feature is proposed in this paper. The algorithm considers the naked body which is composed by trunk, limb and face as the object to be recognized. Body is taken as a combination of predefined key rectangles. The intersection of the key rectangles is the navel. Firstly, the algorithm recognizes the location of navel in an image. Then it constructs the feature vector of key rectangles. Finally, it classifies the features by Forward Propagation neural network to determine whether there is a naked body in the image or not. Experiments show that the algorithm can recognize nude images accurately, and the recognizing speed can satisfy the requirement of practical systems. ©2009 IEEE.

The popularity of wireless communication networks makes them an attractive target to the creators of worms and other malicious code. Indeed, recently a number of worms designed specifically to spread via these wireless networks have emerged. Based on the epidemic theory, this paper proposes a general model which predicts how a worm propagates through a wireless ad hoc network. Then the differential equations of the model is presented and a necessary condition for worms to spread in these networks is derived, which may be useful in designing a secure wireless ad hoc network. Simulation results show that the process of worm propagation in these wireless networks is sensitive to the deployment density of nodes and the energy consumption of nodes. Therefore, our study can provide insight into deriving a general model to characterize worm propagation in wireless ad hoc networks. & copy;2009 IEEE.

Intention recognition is the ability to predict an opposing force's high level goals. Knowing an attacker's intention can support the decision-making of the network security administrators. Furthermore Intent analysis plays an import role in the calculation of the inherent threat value. So how to recognize attack intention has become a research hot in network security domain recently. In this paper taxonomy of attack intention characterized by consequences of attack and targets of attack is introduced at first. Then a graphical model based on network security state is presented and used to recognize attack intention. D-S evidence theory is also introduced to deal with the uncertainty in the process of intent inference. Next algorithms of intention recognition and threat assessment are given in detail in order to offer a way to assess the network security situation. Finally several experiments are done in a local network. The results of the experiments prove the feasibility and validity of this method. © 2009 IEEE.
