Freshness Constraints in the RT Framework

Wojciech Pikulski , Krzysztof Sacha


The work is focused on "time-domain" nonmonotonicity in the RT Framework, which is a Trust Management model. The freshness constraints propagation model that allows for credential revocation is presented. The solution introduces a freshness constraints that turn nonmonotonicity to be temporally monotonic. The freshness graph and propagation rules of freshness constraints are defined. The proposed solution allows policy authors to flexibly define constraints on policy level. Finally, the given model is evaluated against the real-life sample scenario.
