Dynamic and Flexible Access Control for IoT-Enabled Smart Healthcare

This paper proposes a dynamic policy based access control model for the Internet of Things (IoT) enabled smart healthcare. Traditional access control models including Mandatory Access Control (MAC), Discretionary Access Control (DAC), Role-based Access Control (RBAC), and Attribute-based Access Control (ABAC) are based on static policies. This makes policy management very heavy to implement in modern healthcare systems where context changing is highly dynamic, requiring constant policy updating. To overcome the gaps of existing access control models, the proposed solution introduces a dynamic ABAC approach which makes the access policy dynamically adaptive to satisfy emergency and real-time monitoring requirements. Evaluation results demonstrate the effectiveness of the proposed approach.
