Secure Architecture for Web Service Discovery and Retrieval

Web service discovery is a key component in service oriented computing.Service oriented architecture follow the find bind execute paradigm in which service providers register their services in public or private registries which clients use to locate web services.With an increasing number of web services providing similar functionalities,security has become one of the most critical issues. Because search engines are now a major player in finding service access points through Web Services Description Language.Service discovery standards, such as UDDI,have focused primarily on simple keyword-based search methods for service retrieval. When searching for relevant services, clients aren’t interested solely in keyword matching (example, a service or operation name) but, more importantly, the degree to which services can deliver the required functionality.Let clients look for services that meet their requirements, focusing primarily on the overall functionality and security of web service.Here,we regulate security requirements and introduced a technique for negotiating a mutually acceptable security policy based on WSDL and to automate web services based on security factor using agents.
