“…The main focus of existing work in service composition is to address the problem of creating compositions that have certain functional and quality of service (QoS) property (Raman et al, 2002;Ponnekanti et al, 2002;Fujii et al, 2004;Majithia et al, 2004;Jaeger et al, 2004;Aggarwal et al, 2004;Dustdar et al, 2005;Tan et al 2009;Alrifai et al, 2012). This work provides a foundation for functional and QoS properties but provides only basic support for addressing security properties in service composition, which is the main focus of our approach.…”

“…The security of service based systems (SBS), i.e., systems that make use of distributed and possibly dynamically assembled software services, has been a critical concern for both the users and providers of such systems (Raman et al, 2002;Majithia et al, 2004;Anisetti et al, 2013). This is because the security of an SBS depends on the security of the individual services that it deploys, in complex ways that depend not only on the particular security properties of concern but also on the exact way in which these services are composed to form the SBS.…”

Abstract:Security is an important concern for service based systems, i.e., systems that are composed of autonomous and distributed software services. This is because the overall security of such systems depends on the security of the individual services they deploy and, hence, it is difficult to assess especially in cases where the latter services must be discovered and composed dynamically. This paper presents a novel approach for discovering secure compositions of software services. This approach is based on secure service orchestration patterns, which have been proven to provide certain security properties and can, therefore, be used to generate service compositions that are guaranteed to satisfy these properties by construction. The paper lays the foundations of the secure service orchestration patterns, and presents an algorithm that uses the patterns to generate secure service compositions and a tool realising our entire approach.

The term Web Services describes a standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an Internet protocol backbone. Merely providing services to the users in the heterogeneous distributed environments, service oriented systems are very important. Most of the time, the individual services do not have the sufficient conditions to provide any services to the users. In order to resolve the aforementioned problem, one may compose several individual services together. The proposed method currently applied to ensure the robustness and dependability of Web Services compositions do not effectively map to more open dynamic environments. The proposed approach has a new multi-layer Web Services composition model based on Multi-Agent System. We propose a different self-adaptive mechanisms corresponding to different environment's evolutions to improve the reliability of Web Services composition efficiently. Also we introduce an algorithm for dynamic approach to select the best composition. This composition is selected based on the quality and the compose-ability of participated services. Advantage of the proposed approach is to recognize the feasibility of the composition process at any point of execution and produce better throughput and a less consumption of memory to select composition of services dynamically.

Abstract-The paradigmatic shift from a Web of manual interactions to a Web of programmatic interactions driven by Web services is creating unprecedented opportunities for the formation of online Business-to-Business (B2B) collaborations. In particular, the creation of value-added services by composition of existing ones is gaining a significant momentum. Since many available Web services provide overlapping or identical functionality, albeit with different Quality of Service (QoS), a choice needs to be made to determine which services are to participate in a given composite service. This paper presents a middleware platform which addresses the issue of selecting Web services for the purpose of their composition in a way that maximizes user satisfaction expressed as utility functions over QoS attributes, while satisfying the constraints set by the user and by the structure of the composite service. Two selection approaches are described and compared: one based on local (task-level) selection of services and the other based on global allocation of tasks to services using integer programming.
