Design and implementation of Web services security based on message layer

Along with the development of Internet, Web Services technology is a new branch of Web application program, and it has become a hotspot in computer science. 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.
