A. S. M. Kayes, Jun Han, Wenny Rahayu, Md. Saiful Islam, Alan Colman
2017 arXiv   pre-print
Towards this end, this paper introduces a policy framework for context-aware access control (CAAC) applications that extends the role-based access control model with both dynamic associations of user-role  ...  We first present a formal model of CAAC policies for our framework. Using this model, we then introduce an ontology-based approach and a software prototype for modelling and enforcing CAAC policies.  ...  As such kinds of dynamic attributes (contextual conditions) need to be integrated into the basic role-based access control approach, some important issues arise to realize flexible and dynamic access control  ...

Modeling context and situations in pervasive computing environments [article]

Preeti Bhargava, Shivsubramani Krishnamoorthy, Ashok Agrawala
2015 arXiv   pre-print
In pervasive computing environments, various entities often have to cooperate and integrate seamlessly in a situation which can, thus, be considered as an amalgamation of the context of several entities  ...  We highlight several limitations of the existing context models and ontologies, such as lack of provision for provenance, traceability, quality of context, multiple representation of contextual information  ...  Security and Privacy These are implemented in RoCoM using Role Based Access Control (RBAC) for groups and members. A group is an instance of type 'accessgroup' class.  ...
