BCA and trust issues
These issues each affect certain aspects of the BCA architecture
Uncertainty about partners
Aspects of security
Fairness
Trust mechanisms
Advisors, mediatiors, ... (2 more mentioned)
Enforcement
- Discretionary (optimistic)
- Non-discretionary (pesstimistic)
- Mediation and arbitrarion approach
Mediator makes recommendation, may settle
else
Invoke arbitration
- Determination
Use of subjective logic (Josang)
Interesting use of triangle space to represent SL value
I tend to think there's no evidence this stuff is useful in practice.
(Consider difficulty of picking definite approach for content negotiation and q-values)
- 5-level model
execution, mediation, arbitration, correction, failure
