Abstract
En 中文
In the era of the Internet of Things (IoT), where technology has revolutionized our interaction with the world around us and bridged the gap between the physical and digital realms, providing an effective fine-grained access control system is paramount to safeguarding security of the IoT ecosystem. This paper introduces SecShield, a novel Software Defined Network (SDN)-based framework, particularly designed for IoT environments. SecShield operates by evaluating access requests and granting access to IoT services only when the set of defined access policies are satisfied. Utilizing the Attribute-Based Access Control (ABAC) model, SecShield specifies fine-grained access policies for IoT services and employs an algorithm for evaluating access requests. Additionally, the framework incorporates a local cache at the edge of the IoT network, enhanced with a Least Recently Used (LRU) algorithm, to optimize the process of access request evaluation. Experimental results validate the efficiency and feasibility of SecShield, positioning it as a viable solution for improving security of real-world IoT networks.
