Abstract: 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.
