  • TRUST-BASED SECURE INFORMATION SHARING BETWEEN federal GOVERNMENT AGENCIES
    2008
    Co-Authors: Peng Liu, Amit Chetal
    Abstract:

    investigations show that there is a serious information sharing problem among the relevant federal government agencies, and the problem can cause substantial deficiencies in terrorism attack detection. This paper performs a systematic analysis of the causes of this problem; and it finds that existing secure information sharing technologies and protocols cannot provide enough incentives for government agencies to share information with each other without worrying that their own interests can be jeopardized. Although trust-based information access is well studied in the literature, the existing trust models, which are based on certified attributes, cannot support effective information sharing among government agencies, which requires an interest-based trust model. To solve this information sharing problem, this paper proposes an innovative interest-based trust model and a novel information sharing protocol, where a family of information sharing policies are integrated, and information exchange and trust negotiation are interleaved with and interdependent upon each other. In addition, an implementation of this protocol is presented using the emerging technology of XML Web Services. The implementation is totally compatible with the federal enterprise architecture reference models and can be directly integrated into existing E-Government systems. 1

    Journal of the American Society for Information Science and Technology, 2005
    Co-Authors: Peng Liu, Amit Chetal
    Abstract:

    The September 11 attack and the following investigations show that there is a serious information sharing problem among the relevant federal government agencies, and the problem can cause substantial deficiencies in terrorism attack detection. In this paper we provide a systematic analysis of the causes of this problem; and conclude that existing secure information sharing technologies and protocols cannot provide enough incentives for government agencies to share information with each other without worrying that their own interests can be jeopardized. Although trust-based information access is well studied in the literature, the existing trust models, which are based on certified attributes, cannot support effective information sharing among government agencies, which requires an interest-based trust model. To solve this information sharing problem, we propose an innovative interest-based trust model and a novel information sharing protocol, where a family of information sharing policies are integrated, and information exchange and trust negotiation are interleaved with and interdependent upon each other.

  • A Public Health Grid (PHGrid): architecture and value proposition for 21st century public health.
    International journal of medical informatics, 2010
    Co-Authors: Thomas G. Savel, Kenneth E. Hall, Brian Lee, V. Mcmullin, Moses Miles, John Stinn, Peter White, Dan Washington, Terry Boyd, Leslie Lenert
    Abstract:

    Abstract Purpose This manuscript describes the value of and proposal for a high-level architectural framework for a Public Health Grid (PHGrid), which the authors feel has the capability to afford the public health community a robust technology infrastructure for secure and timely data, information, and knowledge exchange, not only within the public health domain, but between public health and the overall health care system. Methods The CDC facilitated multiple Proof-of-Concept (PoC) projects, leveraging an open-source-based software development methodology, to test four hypotheses with regard to this high-level framework. The outcomes of the four PoCs in combination with the use of the federal enterprise architecture Framework (FEAF) and the newly emerging federal Segment architecture Methodology (FSAM) was used to develop and refine a high-level architectural framework for a Public Health Grid infrastructure. Results The authors were successful in documenting a robust high-level architectural framework for a PHGrid. The documentation generated provided a level of granularity needed to validate the proposal, and included examples of both information standards and services to be implemented. Both the results of the PoCs as well as feedback from selected public health partners were used to develop the granular documentation. Conclusions A robust high-level cohesive architectural framework for a Public Health Grid (PHGrid) has been successfully articulated, with its feasibility demonstrated via multiple PoCs. In order to successfully implement this framework for a Public Health Grid, the authors recommend moving forward with a three-pronged approach focusing on interoperability and standards, streamlining the PHGrid infrastructure, and developing robust and high-impact public health services.

    Abstract:

    Ce document étudie les risques associés à une transformation du Centre d’Essais en Vol (Flight Test Centre) de l'UAE AF & AD en une organisation civile compétitive, indépendante et autonome, capable d'entreprendre des projets aéronautiques complexes.Dans cette thèse, l'auteur décrit le FTC « PRESENT », tel qu’il est aujourd’hui, sa mission et sa fonction, tout en ayant comme perspective l'avenir, le FTC « FUTUR ». Il souligne les défis existants et développe les besoins futurs du FTC.L'auteur résume la description générale du Cadre d'architecture d'Entreprise. Dans sa tentative d'identifier le cadre le plus approprié, il compare quatre cadres de référence : « The John Zachman enterprise architecture Framework, The Open Group architecture Framework (TOGAF), federal enterprise architecture (FEA) et The Gartner Methodology ».

The United Arab Emirates Air Force & Air Defence (UAE AF&AD) is also transforming some of its activities from military entities into civilian organizations. This paper studies the risks associated with the transformation of the UAE AF&AD Flight Test Centre (FTC) into a civilian organization to become a competitive, independent and autonomous outsourcing agency able to undertake additional, complex and specialized aeronautical projects.In this paper, the author describes the FTC “AS IS” organization, mission and function while focusing on the future “TO BE”. He underlines the existing challenges and develops the future needs of the FTC. In his mind, it is clear that the future of the FTC has to be sustainable, competitive, process oriented, cohesive and dynamic in response to changes. The need of an enterprise framework is, in the authors view, a critical matter. The greatest challenge is to identify or develop the right framework with a risk dimension and governance for a specific FTC application: a framework that will assist the FTC to identify, determine and assess at an earlier stage various risk
