Research On Malware Propagation In Wireless Environment

With the increase of the varieties of wireless networks and the growth of their applications, the attack of malware has become one of the most important threats confronted by wireless networks. Recently, the study on malware attacks has been one of the most advanced and active topics in the fields of network and information security of the world. The study of malware attack in wireless environment has begun to be a newly arisen topic in the fields of malware research.For different wireless environments, such as Mobile Ad hoc Network (MANET), Wireless Sensor Network (WSN), Bluetooth and Vehicle Ad hoc Network (VANET), the propagation mechanisms are analyzed and discussed based on the study of propagation models of malware. The results of simulation experiments show that, the models presented in this paper can better describe the propagation mechanism of malware in wireless environments, which forms the foundation of designing corresponding control strategies to resist wireless malware.In sum, the main research production achieved in the paper is given as follows:1. Based on summarizing the definitions of such malicious codes as computer virus, worms, a new malware definition is proposed. At the same time, the concept of mobile malware is also proposed.2. After analyzing and comparing several kinds of propagation models of epidemics, we mainly discuss how to improve the traditional epidemic models to describe the propagation mechanism of malware in wireless environment. The conclusion is that the characteristic parameters of wireless networks must be introduced into the traditional epidemic model.3. A propagation model of malware in MANETs is presented, and the propagation mechanism of malware in such network is also studied.4. A propagation model of malware in IEEE 802.15.4-based WSN is proposed after analyzing the TWPM propagation model of malware in it, and the propagation mechanism of malware in such network is also studied.5. A probability model of malware propagation in Bluetooth environment is presented, and the propagation mechanism of malware in such network is researched.6. A malware propagation model in VANET is analyzed and the propagation mechanism of malware in it is studied.
