Abstract. We propose an integrated architecture, extending a framework for fine grained access control of Grid computational services, with an inference engine managing reputation and trust management credentials. Also, we present the implementation of the proposed architecture, with preliminary performance figures.
Abstract. This article presents a lightweight data representation model designed to support real time monitoring of business processes. The model is based on a shared vocabulary defined using open standard representations (RDF) allowing independence and extremely flexible interoperability between applications. The main benefit of this representation is that it is transparent to the data creation and analysis processes; furthermore it can be extended progressively when new information is available. Business Process data represented with this data model can be easily published on-line and shared between applications. After the definition of the data model, in this article, we demonstrate that with the use of this representation it is possible to retrieve and make use of domain specific information without any previous knowledge of the process. This model is a novel approach to real-time process data representation and paves the road to a complete new breed of applications for business process analysis.
The work presented in this paper describes an architecture for a secure Virtual Organization Management framework. This work is taking place in the BEinGRID EU project, which aims to advance the take up of Grid technologies in the business domain by conducting a number of business experiments and in parallel producing a number of components.
The main contribution presented by the authors in this paper is an abstract solution for a secure Virtual Organization Management, based on IBM's Enterprise Grid CompositePattern, and a set of design patterns to develop concrete software components for the above mentioned solution. The patterns presented in the paper represent a first concrete step to support Virtual Organizations that are highly dynamic, for example where the membership can change over time .It is this establishment of trust between businesses and the secure communication between that is the key extension to the Enterprise Grid Composite Pattern.As a concrete case study, we show how the patterns produced can be re-used in a concrete business experiment of the BEinGRID project aiming to implement a implement the Virtual Hosting Environment for distributed on-line gaming applications.
In order to achieve agility of the enterprise and shorter concept-tomarket timescales for new services, IT and communication providers and their customers increasingly use technologies and concepts which come together under the banner of the Service Oriented Infrastructure (SOI) approach. In this paper we focus on the challenges relating to SOI security. The solutions presented cover the following areas: i) identity federation, ii) distributed usage & access management, and iii) context-aware secure messaging, routing & transformation. We use a scenario from the collaborative engineering space to illustrate the challenges and the solutions.
