Access Control in Utilizing Fog Computing for Transport Infrastructure

The integration of the information and communication technologies of cloud computing, Software Defined Networking (SDN) and Internet of Things (IoT) into traditional transportation infrastructures enables the evolution of Intelligent Transportation Systems (ITS). Moreover, the specific requirements for real-time applications and service provision near to consumers introduce the utilization of fog computing as an extension of cloud. However, such a movement affects security aspects and poses new access control challenges. In this paper, we study the operational characteristics of a proposed ITS paradigm utilizing fog computing and identify corresponding access control issues. To address these issues in such a versatile and highly distributed environment, we present the key pointers of an attribute-based access control scheme suitable for fog computing. This paper aims to set a basis for further work in refining, verifying and validating the proposed solution.
