Abstract: In order to ensure the security of mobile communication，the spreading rules of mobile phone virus on short message network are researched.Then，relative measures to control the spreading of the virus are discussed，and a novel propagation model introducing some spreading parameters（such as the infection rate，the inoculation rate，the immune rate，and the failing immunity rate，etc.） of mobile phone virus is proposed.The influences of new parameters are discussed，too.The simulation experiment indicates that new model not only can simulate the process of mobile phone virus spreading，but also give a guide for controlling the spreading of mobile phone virus.

Key words: mobile phone virus, short message network, propagation model

摘要： 为了揭示手机病毒的传播规律，以便更好地为预防手机病毒蔓延提供理论依据，提出了手机病毒在短信网络上的传播模型。新模型引入了传染率、预防接种率、免疫率和免疫失败率等参数，讨论了各参数对手机病毒传播规律的影响。实验结果表明，该模型不仅能够模拟手机病毒的传播过程，而且对控制手机病毒的传播具有指导意义。
