Strengths & Limitations
Strengths
- +Formal proof of soundness, completeness, and termination.
- +Balance of multiple design goals (simplicity, expressiveness, efficiency).
Limitations
The effectiveness of the language might be limited by the complexity of the specific access control scenarios it needs to represent.
Reliability & validity
The study's reliability is supported by formal proofs of the language's properties. Validity is demonstrated through the language's ability to express common policy idioms and its efficient execution strategy.
