1. Terminology and Formalization of Security, Privacy, and Trust for Data and Applications Ontologies for Security, Privacy, and Trust Ontologies for Security, Privacy, and Trust Evidence, Credentials, Behavior Evidence, Credentials, Behavior Personal Privacy vs. Organizational Confidentiality Personal Privacy vs. Organizational Confidentiality Representations and Specifications Representations and Specifications Policies Policies Conditions Conditions Enforcement Enforcement

2. Metrics for Trust, Privacy, Risk, Threats Quantitative metrics like those in fault tolerance Quantitative metrics like those in fault tolerance Vulnerability analysis and threat evaluation Vulnerability analysis and threat evaluation Metrics for trust negotiation and privacy-for- trust trade Metrics for trust negotiation and privacy-for- trust trade Risk management Risk management Economic analysis and tradeoffs and impact on community and society Economic analysis and tradeoffs and impact on community and society

3. New Challenges in Open, Pervasive, and Heterogeneous Environ’s Foundations and common understanding Foundations and common understanding Representation, visualization Representation, visualization Uniform framework for multiple organizational and multiple administrative domains Uniform framework for multiple organizational and multiple administrative domains Conflict resolution and negotiation Conflict resolution and negotiation Data integration Data integration Aggregation and inference Aggregation and inference Data access and dissemination, and Web services Data access and dissemination, and Web services Apoptosis (clean self-destruction) and evaporation Apoptosis (clean self-destruction) and evaporation Data protection techniques: distortion, summarization, encryption and key management, integrity validation Data protection techniques: distortion, summarization, encryption and key management, integrity validation Limitations, incl. low power, small devices in mobile Limitations, incl. low power, small devices in mobile
