  • Abstract
    In classical multilevel access control, classifications and clearance level are defined in advance and does not change during the duration of their use. We thought that the level of clearance of a user can change and that the classification level of an object may decrease after some time. For this, we propose to enrich our description logic reasoner with default and exception JClassicδε with temporal operators to represent the temporal context and the change in levels over time.
