Modular Plans for Secure Service Composition
Service Oriented Computing (SOC) is a programming paradigm aiming at characterising Service Networks. Services are entities waiting for clients requests and they often result from the composition of many services. We address here the problem of statically guaranteeing security of open services, i.e. services with unknown components. Security constraints are expressed by local policies that serv...
متن کاملPlans for service composition
We study how to compose services in the presence of security constraints. By analysing the abstract behaviour of a set of services, we are able to determine the plans that drive safe program executions. These plans can be of different kinds, and we study here three of them, with different expressive power. Simple plans choose a single service for each request; multi-choice plans instead can cho...
متن کاملEfficient Intelligent Secure for Web Service Composition
Service-Oriented Architecture (SOA) provides a flexible framework for web service composition. Using standard based protocols (such as SOAP and WSDL), composite services can be constructed by integrating atomic services developed independently. For each service in the composition, many service providers can offer the same function but may have different non-functional attributes (i.e. security,...
متن کاملInformation Flow Control to Secure Dynamic Web Service Composition
The vision of a landscape of heterogeneous web services deployed as encapsulated business software assets in the Internet is currently becoming a reality as part of the Semantic Web. When pro-active agents handle the context-aware discovery, acquisition, composition, and management of application services and data, ensuring the security of customers’ data becomes a principle task. To dynamicall...
