Proposed Access Control Architecture Based on Fog Computing for IoT Environments

With the growing need for smart devices in our daily life, the cloud paradigm may not be able to adapt to increasing data traffics neither to guarantee a standard level of security. In this context, Fog Computing extends cloud computing services to the edge of the network and could be integrated with Internet-of-Things (IoT) to enable computing services for such devices. Thus, improves security, efficiency and reduces the amount of data transmitted across the network to the cloud for processing, analysis, and storage. In this paper, we present a comparative study of fog computing architectures then we suggest our distributed model in order to face the IoT access control problems using the XACML language in a Fog Cloud.
