了解手机病毒的传播模式
Understanding the spreading patterns of mobile phone viruses
摘要：
我们模拟移动电话用户的移动性，研究移动病毒爆发的基本传播模式。我们发现，虽然蓝牙病毒可以达到所有易受感染的手机随着时间的推移，他们传播缓慢，由于人类流动，提供了充分的机会，部署抗病毒软件。相比之下，利用多媒体消息服务的病毒可以在数小时内感染所有用户，但目前底层调用图上的相变将它们限制在仅一小部分易受影响的用户中。这些结果解释了迄今为止没有重大移动病毒爆发的原因，并预测一旦移动操作系统的市场份额达到相变点，病毒将对移动通信构成严重威胁。
英文摘要：
We model the mobility of mobile phone users to study the fundamental spreading patterns characterizing a mobile virus outbreak. We find that while Bluetooth viruses can reach all susceptible handsets with time, they spread slowly due to human mobility, offering ample opportunities to deploy antiviral software. In contrast, viruses utilizing multimedia messaging services could infect all users in hours, but currently a phase transition on the underlying call graph limits them to only a small fraction of the susceptible users. These results explain the lack of a major mobile virus breakout so far and predict that once a mobile operating system's market share reaches the phase transition point, viruses will pose a serious threat to mobile communications.
