TAS3_D1p2 Requirements Assessment Report v229052009.pdf

Requirements Assessment Report Accepted by European Commission in June 2009. Executive Summary: The objective of Deliverable 1.2 is to gather requirements regarding unsolved problems in the field of security and trust in service-oriented open and distributed environments that apply to the TAS3 project. Specifically, the deliverable translates the design requirements defined in Deliverable 1.4 [21] into the research and development activities that will be carried out in the different TAS3 WPs. In order to fulfill the objectives of this deliverable, we have completed a number of sequentially ordered activities. The results of these activities are documented in the different sections while some of the material we used and collected is included in the Appendices. First, we have reviewed the objectives of each work package and the solved and unsolved problems they are addressing with respect to the objectives of their work package. Next, we asked partners to elaborate or refine requirements based on these objectives and scenarios provided by the demonstrators in D1.4. Then, we compared the requirements elaborated by the TAS3 partners with the existing solutions for trust and security in service-oriented open and distributed environments. Last, we identified research and development challenges to be addressed by the partners in their future activities in order to fulfill their requirements. Last, we mapped the requirements to the TAS3 architecture. Some of these activities are to be re-iterated in the future based on our current analyses. In addition, in order to prioritize activities and discover interdependencies within and among work package activities, we analyzed requirements interactions in each WP. We have also analyzed the interdependencies among requirements elicited in different WPs. The prior interactions are represented in form of graphs to support the analysis, and the latter interdependencies in tables with the future prospect of visualizing inter-WP requirement interactions. The inter-WP requirements interaction analysis provides the partners with an understanding of the relationships between WPs. We expect the results to support the partners in partitioning their requirements and temporally ordering their activities in the future. Hence, the contribution of the deliverable is threefold. It provides a gap analysis which is used to map out future activities. The deliverable also elaborates on the technical, legal, policy and application domain requirements of TAS3. In addition, it gives an initial analysis of the interaction of the TAS3 requirements and maps out responsibilities and necessary cooperations for fulfilling these requirements as perceived by the WPs. Readers Guide: Section 3 provides a review of the objectives of each work package and the objectives are related to solved and unsolved problems in the field of security and trust in service-oriented open and distributed environments. Section 4 provides an analysis of the technical, legal and application domain requirements that address the solved and unsolved problems related to TAS3. The technical, legal, policy and application domain requirements elaborated for D1.2 are documented in Appendix B. This detailed listing of the requirements includes the justifications for each requirement and the interactions of each requirement within each WP. Section 5 provides the results of the first round of inter-WP requirements interaction analysis. Section 6 maps the requirements to the Architecture. Section 7 provides an analysis of the requirements fulfilled by existing solutions. The justifications for selected solutions are summed up in Section 7 and are included in detail in Appendix C. The templates we sent out to all the partners for requirements, requirements interactions, and existing solutions is included in Appendix A. Section 8 lists the activities that each work package has to complete in order to fulfill the requirements that cannot be fulfilled using existing solutions. We conclude in Section 9.
