  1. TIUPAM: A Framework for Trustworthiness-centric Information Sharing Shouhuai Xu Univ. Texas at San Antonio Joint work with Qun Ni and Elisa Bertino (Purdue Univ.) Ravi Sandhu (Univ. Texas at San Antonio)

  2. Goal • A systematic framework for information sharing • Trustworthiness-centric Identity, Usage, Provenance, and Attack Management (TIUPAM) • Four supporting components: • Identity management • Usage management • Provenance management • Attack management • The framework is centered at the need of trustworthiness and risk management for decision makers

  4. Architecture of TIUPAM trustworthiness and risk management provenance management usage management identity management attack management
