EHR Attribute-Based Access Control (ABAC) for Fog Computing Environment

摘要

Cisco recently proposed a new computing environment called fog computing to support latencysensitiveand real time applications. It is a connection of billions of devices nearest to thenetwork edge. This computing will be appropriate for Electronic Medical Record (EMR)systems that are latency-sensitive in nature. In this paper, we aim to achieve two goals: (1)Managing and sharing Electronic Health Records (EHRs) between multiple fog nodes andcloud, (2) Focusing on security of EHR, which contains highly confidential information. So, wewill secure access into EHR on Fog computing without effecting the performance of fog nodes.We will cater different users based on their attributes and thus providing Attribute Based AccessControl ABAC into the EHR in fog to prevent unauthorized access. We focus on reducing thestoring and processes in fog nodes to support low capabilities of storage and computing of fognodes and improve its performance.
