Design And Implementation Of MMS System In WM6.0 Smart Phone Based On Data Encrytion

With the development of mobile communication technology, terminal services not only brings great profit to the mobile service providers, but also has enriched the service pattern(such as video,MMS) and becomes the new growth direction of mobile network besides original voice servicess。However, the development also encountered some problems。Mobile network own security issues for mobile Value-Added(VAS) services is becoming a threat to internal security, and the diversity of mobile VAS has also involved a variety of personal privacy information which is important to be protected。Therefore,study for the security of data in mobile VAS system is inevitable。In this article,the communication security of data in mobile VAS system was selected as a research subject。From mms data, it utilized all mature symmetric and asymmetric encryption algorithms, and designed secure and authenticated all-purpose transmission protocol of TS 23.140, then developed a typical application named MMS system based on smart phone。The security algorithm, security communications was also the research focus。The limited communication environment。how to code MMS,how to encode MMS and the improvement of MMS protocol were also considered。At last,with this common protocol,MMS system was designed and implemented。...
