D4.1. A Proposal for Access Control Models for Multitenancy

This deliverable will assess current approaches for access control and propose novel models, based on current progress in ABAC models, to cope with multi-tenancy requirements and in particular with distributed attributes.
A mapping between these ABAC-based models to enforceable policy languages (e.g. XACML) will be proposed, including the design of an enforcement component to parse, interpret and execute access control policies.
