SX-RSRPM: a security integrated model for Web services

The conceptions about security of Web services and degree of safety for Web services (WS-DoS), which is a qualitative analysis index of Web services security and is influenced by the degree of credible environments around WS-based applications and the duration of Web service execution time, are introduced in the paper. In addition, a securing logical hierarchical structure for Web service application based on an extended Web services security architecture model with five elemental objects, such as resources, services, roles, protocols and methods object is analyzed, which can effectively increase the value of WS-DoS by a new affiliated role as security certification and authentication center and the extended security of protocol stacks. Moreover, an integrated security solution has been developed and the results of application show that this solution builds a confidence and an authentication security environment for all roles in the process of dynamic B2B trade.
