Embedded 3G Mobile Firewall Design And Research

As we know, the intelligence of mobile phones has been completely transformed. Currently, many smart mobile-phones and PDA features nearly comparable to the traditional handheld smart devices. Smart phones with operating systems not only process as the word as a computer text editor, file storage, copy, and even print via Bluetooth technology to scan documents, listening to the radio, listening music, watching TV and other functions. Today with the rapid development of the network,3G mobile phones become more and more popular, phone from single to multi-functional to diversification, to some extent play a role as PC, like PC, time of 3G mobile phone also facing security problems.General mobile phone security mainly focused on three aspects:phone communication services, send or receive SMS and MMS, in addition to these two kinds of security, more important is the Internet expansion, in personal business calls harassment and spam messages received. When downloading data from Internet, Web browsing, Bluetooth and infrared receiver, such as, send and receive MMS, mobile phone virus infection of modern network technology, received a malicious program, so that the safety of users are greatly threatened.Today, big phones on the market have call firewall, the technical principle is based on text filtering technology to enable the firewall options in black and white list filtering, SMS firewall is also based on this, these two Firewall may well achieve the desired effect, but in which the firewall is important to ensure the safety of mobile Internet, can not be fully protected on the mobile phone business.Mobile as PDA, have no real firewall, this firewall based on some existing 3G mobile phone firewall model proposed, the firewall on the existing mobile phone firewall certain improvements to the functionality of organic Combination, the realization of SMS, Call, Internet access and mobile phone integrated treatment of the virus. Details of This model mainly includes four function models, dealing with the filtration of abnormal calls and messages, making network monitoring and killing the phone virus. Besides, this model also provides the function of log recording. In this paper, the design objective, the interface design, file structure design will also be concerned.
