The Analysis Of Virus Of The Cellphone And The Software Design Of Antivirus Of Intellectual Cellphone

The function of the cellphone is more and more abundant at present. It has already no longer confined to conversing. More functions have been planted into the cellphone. From chatting to surfing in the Internet with cellphone, various resources begin to pour into our cellphone. During this period, the virus of the cellphone arises at the historic moment too.With the arrival of 3G era, it is the one of the important functions of the cellphone to be insertted into Internet and obtain a large number of information, and it increased the chance for the cellphone to be infected with the virus too.But no matter the attention degree on the thought, or the dynamics of investment on the research fund, far lag behind the development with the virus of the cellphone.Everybody seems to present a kind of atitude looked around to this.In order to take precautions against the virus of the cellphone more efectively, the study on virus of the cellphone has been already very urgent.Then enumerated the atack instances of several pieces of cellphone virus, and carry concrete analysis on three kinds of typical cellphone virus among them, including influence, realizing mechanism and deleting the method.Because cellphone infect with the virus through short sms and Java applet which down load from Internet, so it must been analysed which the security risks of the business system of short news and a Java applet, and put forward the corresponding countermeasure. According to the five important factors for cellphone viruses which spreads by Bluetooth: the range of cellphone moving, distribution density, coverage radius of Bluetooth signal, spreading ability of virus and people's security consciousness. Author build dynamic models of virus spreading by bluetooth, then according to this model discussing the threshold of virus spreading, influence of parameter's change to virus spreading. Then author make an introduction and prospect the anti-virus technology, and analyse the virusm echanism of several kinds of intellectual cell-phone virus, thus design the systematic model which detects the web page viruses according to the analysis result of the web page viruses.
