A Study On Data Encryption And Compression In Mobile Commerce Based On XML

The perfect combination of Internet, mobile communication techniques and computer etc, produces the application of M-commerce. With the development of M-commerce, ordinary customers can benefit from engaging tickets, paying fees, stock exchange and other financing services. Nowadays more and more merchants and customers are becoming enjoy M-commerce service for its agility, simplicity and convenience. At the same time, M-commerce can't be run without the support of data operation. With all kinds of mobile equipments, the first problem that exits between enterprises and enterprises, or enterprises and clients, is to unify the format of data during the course of data exchange. As an universal eximious language, XML can describe information compatible and indistinctively in different platform, which provides scheme of sharing information for M-commerce. There are also many problems need to be settled when it come into the stage of implementing, and the most nuclear and pivotal two are dealing's safety and data transmission speed.On the one hand, the unsafe factors that exist in mobile network endanger user's personal information. Considering protect their economic advantage, some kind of safety operation must implemented to eliminate such factors; on the other hand, XML has a nature of redundance though it has many excellent characteristics. The compression techniques must also be considered in wireless network circumstance that has limit bandwith and storage space.Based on XML'S strong ability of processing data, the thesis brings forward a scheme of M-commerce data platform, and realizes two pivotal techniques which include data encryption and compression of XML documents. This measure makes intercommunion between mobile terminals or mobile terminal and data server become more safe and effective. The whole process adopts XML as the agency of data exchange, which brings great consistency and agility for implementation.
