IoT Framework for Effective and Fine–Grain Access Control

The standardized protocols and new generation of hardware for communications increased interoperability more than ever. However, the increasing interoperability causes a rise in offensives from vicious people and hardware. Therefore, there is a necessity to apply encryption algorithms to guard the communications between clients and servers. Nevertheless, the current encryption techniques do not protect the service access at a fine-grain level. Furthermore, in wireless sensors and actuators, each network endpoint is integrated constrained–resource; thus, the interoperability increase necessitates a high computation rate. On the other hand, the endpoints inherent to processing and memory restrictions negatively affect communication delays and power consumption, leading to a shorter battery lifetime. Consequently, there is a need for new methods to increase interoperability, dependability, scalability, security, and energy efficiency. This study proposes a theoretical design of a new and effective IoT model that supports authentication, authorization, and fine grain access control with no network configuration and dynamic reconfiguration. The proposed framework demonstrates the possibility of the integration of IoT devices powered by batteries and a functional System of Systems.
