Research On The Security Technology For Web Services

Research on Web Services security technology problem is an issue with importantlytheoretical and practical significance. The Web Services based on XML has an importantinfluence for promoting the services compatibility and the project integration. The securityhas become one of the important reasons for hindering the Web Services as the existingmeasures can't guarantee the security of Web Services. The Web Services security mainlyinvolves the end-to-end integrity, the confidentiality and authentication for messageprocessing.In foundation of studying the computer network security and related techniques, thispaper firstly evaluate the performance of Web Services. It nextly constructs the Web Servicessecurity model based on the SOAP information registration and security token proxy. Thispaper verifies the validity and security for this model based on the theory of Pi-calculus. Thedetailed contents studied in the paper are as follows:(1) The research of the performance evaluation for secure Web Services. It analyses theWeb Services architecture and performance evaluation, does the research of time responseappraisal model with emphasis and gives the improved time response evaluation model. Italso gives the material experiment results in the laboratoryenvironment. The results show thatthe Web Services security shouled be considered with service performance and the securitymeasures should be made bydifferent requests.(2) The research on the construction for Web Services security model. This paperanalyses the security requirements and gives the overall design and detailed description forthe Web Services security model. It does the research of the message processing andworkflow for SOAPsecurityinformation registration and securitytoken proxyservices.(3) The verification for Web Services security model. It studies the related theoretical knowledge of Pi calculation and does the research on MWB platform and fix-point. Thispaper gives the formalizing description for Web Services model and does the research onsecurityand validityfor it.The research in this paper has used the method which the experiment and thefundamental research develop simultaneously based on the computer information security andmathematics intersecting. It is the beneficial exploration for solving the Web Services security.The research result in this paper can provide the backward measures and efficiency improvingand widespread application ofWeb Services.
