1. Graph-based security modeling - risk models, optimal security hardening,resiliency 
   
2. Trust models - non-binary context sensitive model of trust
   
3. Access control models
   
4. Security protocols
   
1. fair-exchange protocols
2. access control protocols
3. protocols for network survivability
   
4. authentication protocols
5. anonymous protocols
6. secure group communication protocols
   
7. voting protocols
8. secure logging
   
5. Privacy
1. privacy preserving search over encrypted data
   
2. micro-data disclosure control
3. privacy preserving protocols, and
   
4. location privacy
6. Data and applications security
   
1. Security of smart grids
