However, it has not made great progress in research on Web Services security. Traditional security solutions cannot satisfy the Web Services security require of selective protection, end-to-end security and application layer security. Web Services technology needs a solution integrated in Web Services framework to realize end-to-end security. Based on cryptography and Web Services technology and according to W3C, XML encryption specification, XML digital Signature specification and WS-Security, which proposed by IBM and Microsoft, a new Web services security model based on message layer is put forward in this paper. The message layer is composed of message handlers. It is inserted into the message processing sequence and provides transparent security services for Web Services. To verify the model, a Web Services security system is realized on, net platform. The implementation version of the model can provide various security services, and has advantages such as security, scalability, security controllability and end-to-end security in message level. Key words Web services - Web services security - message layer CLC number TP 393.08 Biography: WANG Cui-ru (1954-), female, Professor, research direction: database and information management system.展开更多

The command （Web Service Call） is recursively muhicast from top layer of tree to bottom layer of tree and statistical data are gatbered from bottom layer to top layer. We implemented the architecture by using Web Services technology. In our implementation, client program is the requestor of Web Services, and all leaf nodes of the last layer are only the provider of Web Services. For those nodes of intermediate layers, every node is not only the provider of Web Services, but also the dispatcher of Web Services. We take population census as an cxample to describe the working flow of the architecture.展开更多
