Personalization or privacy control? is a question one frequently asks himself/herself nowadays with the wide spread of service provision for users on the move. The right to protect intimacy or the right of privacy is a permanent and genuine right of any person. Context-awareness, offering to users services that react proactively to user environment and service conditions, although desirable, breaks...
Many web services represent their artifacts in the semi-structural format. Such artifacts may or may not be structurally complex. Many existing test case prioritization techniques however treat test cases of different complexity generically. In this paper, we exploit the insights on the structural similarity of XML-based artifacts between test cases, and propose a family of test case prioritization...
The web service community has introduced many techniques to cope with the inability of WSDL to describe a service's behavior. Those techniques range from embedding more XML tags in WSDL, to generate formal behavioral models on top of WSDL. Apart from the efficiency of these techniques, a common problem is that they require manual efforts to model the behavior of a service, and often need informal...
Software agents controlling production devices must maintain an up-to-date view of the physical world state in order to efficiently reason and plan their actions. Especially in a factory automation system, the world state undergoes rapid evolution, and the world view must remain synchronized with the changes. This paper discusses two approaches to updating the world view based on event notifications...
SOAP-based Web services is a middleware technology marketed as the solution to easy data exchange between heterogeneous IT architectures. The large number of scenarios, in which this technology is used, has introduced demands for new extensions raising its complexity. However, this has also introduced a large variety of new attacks. In this paper, we investigate an automatic evaluation of Web service...
Many Web APIs (by which we mean ones using HTTP as the application protocol) do not publish a machine-readable API description (in a language such as WADL or WSDL) but only provide human-readable documentation, usually in HTML. This documentation may be machine-generated, or it may be hand-edited in which case there is the possibility of errors being introduced into the API description. In this paper...
The similarity-based aggregation of XML documents is a proven method for reducing network traffic. However, when used in conjunction with XML security standards, a lot of pitfalls, but also optimization potentials exist. In this paper, we investigate these issues, showing how to exploit similarity-based aggregation for rapid distribution of digitally signed XML data. Using our own implementation in...
Since current heterogeneous Intrusion Detection Systems (IDSs) have not been designed to work in a cooperative manner, sharing security information among them poses a serious challenge especially in large-scale High Speed Networks (HSN) environment. The integration become more difficult when we should reduce computing and memory costs incurred by the high speed IDSs communication. Fortunately Web...
