摘　　要：随着手机等移动终端的普及和智能化,一系列新的攻击手机等无线终端的蠕虫不断出现,移动网络的安全性面临严重危机.这些新型蠕虫与传统的基于互联网络传播的普通病毒和蠕虫不同,这些蠕虫的传播不需要借助于Internet连接,他们往往利用Bluetooth、WiFi等短距离无线通信技术进行广泛传播.本论文主要利用统计物理和复杂网络的研究方法,研究无线网络特别是3G网络中蠕虫的传播机制及其动力学行为.在本项目研究过程中,我们提出了一个新的蠕虫传播模型,在该模型中,我们将传统的SIRS模型应用于无线网络传播中,同时借助扩展的蒙特卡罗研究方法.本项目详细研究了3G网络蠕虫的传播机制,得到了不同于普通主机蠕虫和SIR无线蠕虫传播的机制和传播阈值,本论文的结论将为3G等无线网络的安全应用及控制提供相关支撑.With the increasing popularity and intelligentization of mobile devices,the security of mobile wireless networks is confronted with the challenge of endlessly emerging worms.Different from the traditional computer viruses,they propagate their copies through short-range wireless communication technologies such as Bluetooth,WiFi,etc.This paper studies the mechanism and the dynamics of worm propagation in wireless 3G networks by means of statistical physics and complex network theory.We propose a new worm spreading model,in which the classical SIRS model has been introduced and the extended Monte carol method has been adopted.We find out that the phenomena of worm propagation in 3G networks is very distinctive,compared to those in the Internet and SIR model in wireless networks.The findings would provide some theoretical hints for controlling strategies.
