Mobile Office System Communications Security Design And Implementation

It's the mobile communication technology development and mobileterminal function unceasing strong that make mobile office more and moreimportant in the role of daily office.It has solved that kind of business whichcan't be handled because of evection or other reasons,and ensure that the usercan be in any time any where processing business related things,greatlyimproving the office efficiency.As mobile office has become more and morepopular, mobile office of the security of data transmission is becoming more andmore important. Mobile client and server will communicate by publiccommunication network,such as GPRS,CDMA, in between the data istransmitted through proclaimed, information security can't be guaranteed,So,raising the level of security between the mobile phone client and server datatransmission is very important.First,this subject adopts Windows Mobile6.0as a client developmentplatform, The operating system is largely used in PDA mobile client and themobile phone operating system. Using the mature Web Services developmenttechnology designs and realizes the communication modules between the clientand the server.Through the analysis for the characteristics of the symmetricalencryption and asymmetric encryption, I decided to use mixed encryption toachieve data encryption transmission between the mobile phone client andthe server. Through performance comparison and analysis of many of theencryption algorithm, conform the mixed encryption system of based onAES-RSA algorithm.Second,the paper puts forward a suitable communication mode for datasecurity transmission of mobile client and server. The mode is based on WebServices communction technology implementation,and through a mixture ofencryption to realize the data security transmission.It is mainly discussed thatthe design of communication mode and the realization methods of concrete inthe paper.Finally,Paper completes the detailed design based on AES-RSA algorithm,and realized the data encryption transmission between the mobilephone client and the server, providing certain reference value and the researchsignificance of two data security transmission.
