一种蓝牙环境下恶意程序的传播模型

Malware propagation model in bluetooth networks

在分析蓝牙恶意程序传播过程的基础上,将蓝牙协议的作用及设备移动方式抽象为若干个统计学参数,通过理论推导建立了一种蓝牙恶意程序传播动力学的分析模型.该模型表明,认证机制等安全措施的引入可大大降低蓝牙恶意程序的传播过程,这对设计安全的蓝牙协议及设备具有积极的意义.仿真结果表明,该模型能够很好地描述蓝牙环境下恶意程序的传播特性.

Based on the analysis of the Bluetooth malware propagation process, an analytical model of its propagation dynamics is established by means of theoretical derivation after abstracting the function of Bluetooth protocols and the mobility of Bluetooth devices into several statistical metrics. The model illustrates that the introduction of authentication mechanism can greatly decrease the propagation speed of Bluetooth malware, which is of great importance to design security Bluetooth protocols and devices. Simulation results show that our model works well.
