Based on the Agency Web Service Security Architecture

Pick the paper describes the service oriented architecture of background, and analyzes the Web services based on service oriented architectures of the application system of safety defects existing. Combined with agent technology and Web service technology, puts forward the respective advantage based on the agency Web service security architecture, and designs the client and the server proxy security processing module, expounds how to handle each module, to realize a SOAP message level security function, news and improve the performance of the system processing news. Keywords-Service oriented architecture, Web services, agent I. PREFACE With the deepening of the informatization construction of enterprise, corresponding application system is becoming increasingly complex, how to effectively organize and USES the enterprise scattered IT capital to become the enterprise information construction process had to cross the barrier, and service oriented method for overcoming the difficulties of an opportunity. Service Oriented Architecture (Service - Oriented Architecture, SOA) is a kind of flexible distributed systems design and integration method, based on SOA application system will system function to encapsulate the form of interactive services, making the Service can be other application system reuse. With more and more enterprises to adopt SOA constructs the enterprise the basic application, and because the system between the open and service, make the interactivity of the safety of the SOA system step by step, and exposed widely attention. Article SOA analyses present the security of the system, and from the network layer, business process, summarizes three levels of the system software service oriented architectures system must consider the security objectives. In the SOA Security " in the book the author analyzes the traditional safety technology in dealing with SOA system Security deficiencies, and puts forward three new methods to deal with this kind of system safety problems, this includes: news Security protection, safety namely service, strategies driven safety .proposes model driven method. Domestic to SOA system security research although started quite late, focus on the safety of Web service with the combination of services in security, article have reflected. The above safety technology in the process of realizing isn't a good and the application of the system logic completely separated, cause the system application and safety of strong coupling, to bring the difficulties the reuse of the system. So had to consider service oriented security architecture design, this paper based on this background is proposed based on agent service oriented security architecture, through an agent to achieve the Web service in a SOAP message encrypted and signature processing, achieve end-to-end news level security and reduce the system coupling.
