Supervisor research project granted by Polish Ministry of Science "Selective Semantic Modeling Method SSM for Building Secure Multiaccess Virtual Environments".

The SSM method enables modeling of privileges for virtual environment behavioral resources with respect to their semantics. The SSM method is based on the concept of semantic operations. Semantic operations are generated at run-time from the virtual environment’s current data model and are applicable to the access control model as a part of a privilege. Semantic consistency of the privilege set is forced by a two-phase regeneration and validation mechanism, so that user privileges can still be expressed in a precise, semantically accurate and flexible way.
