INTRUSO 2011 1st INternational Workshop on TRUstworthy Service-Oriented Computing Affiliated with 5th IFIP International Conference on Trust Management (IFIPTM‚11) Copenhagen, June 27, 2011, Technical University of Denmark

Service-Oriented Computing (SOC) is an emerging paradigm for distributed computing aiming at changing the way software applications are designed, delivered and consumed. SOC is triggering a radical shift to a vision of the Web as a computational fabric where loosely coupled services (such as Web services) interact publishing their interfaces inside dedicated repositories, where they can be searched by other services or software agents, retrieved and invoked, always abstracting from the actual implementation. The proliferation of such services is considered the second wave of evolution in the Internet age. In order to realize this vision and to bring SOC to its full potential, several security challenges must still be addressed. In particular, consensus is growing that this „service revolution‰ will not eventuate until we resolve trustworthiness?related issues. For instance, lack of consumer trust and Web service trustworthiness still represent two critical impediments to the success of Web service-oriented systems. Although software trustworthiness is a wide topic, far from being an issue only for SOC, the intrinsic openness of this vision makes it even more crucial. The SOC vision, indeed, faces with a large, open and dynamic service-oriented environment where anyone can publish his own (even malicious) services. In this scenario, a client (human or software agent) faces a dilemma in having to make a choice from a bunch of services offering the same functionalities. Thus, selecting the right service requires addressing at least two key issues:

1. Discovering the service on the basis of its functionality 2. Evaluating the trustworthiness of the service (how well the service will work)

Although concrete applications coping with the first issue are far from being widely adopted, the significant effort spent on its investigation in the current literature is recognizable (OWL-S and the SOAP/WSDL/UDDI Web service framework to mention only some contributions). Instead, service trustworthiness is still in its infancy and represents a barrier for widening the application of service-oriented technologies. The open and dynamic nature of the SOC vision raises new challenges to traditional software trustworthiness. Indeed, in a traditional closed software system all of its components and their relationships are pre-decided before the software runs. Therefore, each component can be thoroughly tested as well as its interactions with other components before the system starts to run. This is not possible in the SOC vision due to its openness and dynamicity. For instance, in the Web service dynamic invocation model, it is likely that users may not even know which Web services they will use, much less their trustworthiness. Traditional dependability techniques, such as correctness proof, fault tolerant computing, testing, and evaluation and more in general „rigorous software development‰ might be used to improve the trustworthiness of Web services. However, again these techniques have to be redesigned to handle the dynamicity and openness of SOC.

The 1st INternational Workshop on TRUstworthy Service-Oriented Computing (INTRUSO 2011) aims at bringing together researchers, engineers and practitioners interested in all the different aspects of Trustworthiness and Dependability in service-oriented environments. Since the overall goal of Trustworthy SOC includes the investigation of several cross-disciplinary issues such as a deep understanding of trust vs. trustworthiness in a service domain, trust-based approaches for service rating and selection (reputation systems, recommendation systems, referral networks∑), service dependability, service evaluation/monitoring/testing, etc∑, a synergy between different scientific communities and research disciplines is needed. For this reason, although the workshop seems naturally focused on SOC-specific issues, contributions from different disciplines such as philosophy, sociology, psychology, communication sciences, as well as from computer science specific sub-disciplines such as software engineering and dependability are welcomed and encouraged.

The workshop is expected to stimulate discussions about the future development of appropriate models, methods, notations, languages and tools for building a variety of trustworthy service-oriented systems.

Topics of interests include, but are not limited to:

* Trust and trustworthiness in the Web service domain * Trust-based approaches for Web service rating and selection (reputation systems, recommendation systems, referral networks, ∑) * Trust negotiation for Web services * Service monitoring and testing * Service dependability * Fault-tolerant mechanisms for SOC * Security for SOC * Architectures for trustworthy SOC * Software engineering methodologies for trustworthy SOC (e.g., deployment life cycle for trustworthy services) * Policy assurance for trustworthy SOC * Formal methods and frameworks for trustworthy services * Quality of Service (QoS) for service discovering and trustworthiness * Case studies on trustworthy SOC * Industrial experiences in the adoption of trust-based approaches for SOC * Rigorous Software Development to ensure service trustworthiness

Submitted full papers must not exceed 16 pages in length, including bibliography and well-marked appendices. Papers can be submitted using the following link on EasyChair:

Submitted papers will be evaluated by the program committee and chosen for presentation based on their scientific contribution and relevance to the topics of the workshop. At least one author of each accepted paper must register to the workshop and participate presenting the paper.

The collection of the accepted papers of all the IFIPTM workshops will be published in a technical report at Technical University of Denmark (DTU). We have already agreed with the editor of the international Journal of Internet Services and Information Security to have a special issue in November 2011 with extended versions of best papers selected from IFIPTM workshops.
