Benign Worm Propagation And Control Research In Mobile Network

With the high growth of the size of mobile Internet market and the number of users, the applications, such as M-Commerce, M-Payment and Social Network, develop rapidly. Lacking of effective security-defense products, mobile terminal security defense system is very fragile. In the android market, many applications can be modified randomly because of the openness of the platform, so that the worms and other malicious code can disseminate more easily along with the spread of these free mobile applications. Android platform is still the harder-hit area of the mobile security, and the rapid development of the Internet of Things will also bring serious ordeal for the mobile Internet security. Obviously, the security problem in the mobile network is rather serious. We need to analyze and control the propagation of the worms in the mobile network environment, and combine the characteristics and advantages of benign worms to design a reasonable repairing control scheme for mobile network, so as to prepare for the mobile network risk that may erupt at any time.Firstly, this paper elaborates the concept of mobile worms and mobile benign worms, analyzes the propagation characteristics of worms in the mobile network environment, and proposes the corresponding propagation model of mobile worms. From the analysis of this model in this paper, we know that the number of the worms in the mobile network environment can be reduced through three ways. Through the simulation experiment, we can know the influence of several parameters on the model. Secondly, this paper proposes the repairing and control mechanism of mobile benign worms based on double stage, dividing the propagation control process of mobile benign worms into active repairing stage and passive repairing stage. We respectively establish the propagation model in accordance with the propagation characteristics of benign worms in different stages. The simulation is used to analyze the model characteristic, as well as verifying the effectiveness of mobile benign worms. Finally, this paper studies the benign worms repairing strategy based on the mobile social network. We build a graph in accordance with the mobile social network, and conduct the clustering partition for the nodes in the social network graph. The nodes with close relationship are put into the same subdivision, so that it makes the nodes in different subdivisions not that close, thereby indirectly reducing the infection rate of worms in the whole network. This paper presents the partitioning algorithm based on K-means to divide the mobile social graph. Through the simulation experiment, it analyzes the effect of the algorithm and verifies the effectiveness of benign worms repairing mechanism based on the mobile social network.This paper studies the propagation control of mobile benign worms. Through analyzing the propagation characteristics of mobile worms and benign worms, this paper proposes the strategy of worms repairing control in different cases, which has certain reference significance to study the control of mobile worms and the repair of mobile network.
