Design And Realization Of Web Services Based Secure Logistics Providing And Delivering System Model

Through making investigations in a large amount , find two difficult problems existing in online logistics system at present: the secure electronic payment problem of the freight charges and the trust problem during owner of cargo and car owner. For this reason, this paper has designed a model of secure logistics providing and delivering based on Web Services, and also provide the scheme of realization based on J2EE platform.Electronic payment is the foundation that the online logistics system can launch the business in order. On solving the security electronic payment of the freight charges, this system is on the basis of analysing technological difficult point of mode of electronic payment based on SET protocol, combine the technological advantage of Web Services, has put forward a kind of new electronic payment scheme. Namely adopt the solution that is put forward in XKMS to build up the authentication system of the identity. The client and trust services communicate with each other by SOAP message which accord with XKMS format. It has simplified the identity authentication course, thus simplified the complicated authentication mechanism of the SET mode, has solved the problem of disunity of communication platform participating in paying, makes the traditional payment, system easy to dispose and implement. At the same time, this system has security of height, since adopting SET protocol as the basic procedure frame.To solve the trust problem of trade companies, this system has introduced the third party, namely logistics providing and delivering center. The providing and delivering center of the logistics is not merely the information exchange platforms, but also serves as the role of the guarantor between the owners of cargo and the car owners. Main Web Services that the center offers includes: Information issue and inquiry service; Sign a contract service; Freight charges payment service. By these web services, it offers credit to owner of cargo and car owner not knowing; each other, enable both sides to rest assured to conclude the transaction through Internet.What the whole system adopted is Web Services system structure based on XML technology. Web Services enable relevant enterprises to structure and integrate every web service that this system offers fast and conveniently, to ease the enterprises application maintain working, and the data interchange between the application systems becomes easier and easier to implement too. Every service in this system is offered by way of Web Services in standard SOAP, thus the system reduces the communication protocol kind that must be supported for the client, and the configure demand of the client equipment, and lay the foundation for the development of system and business too.This system adopts WS-Security to protect the SOAP message by providing integrality, confidentiality and message authentication.This system is realized on the J2EE platform. It takes full advantage of the security and portability of Java. Developing tools that the system adopts are Axis and Trust Services Integration Kit.
