Dynamic Cross-Domain Authorisation Model

This research study is focused on evaluating the influence of security, privacy and access control on multiple-domains (e.g., the healthcare domain). In this thesis, we addressed the problem of central access decision systems by introducing an appropriate cross-domain healthcare scenario based on current issues and interaction of relevant entities in cross-domain environments. This work has enabled us to introduce decentralised access control, a novel policy system for dynamic cross-domain authorisation that uses elements of both the traditional access control model and cryptographic primitives. These kinds of algorithms and systems are fundamental in developing Industrial applications (e.g., healthcare) to secure the confidentiality, integrity and availability of this sensitive data and prevent unauthorised user access in the cross-domain environments.
