Pervasive-Based Access Control Model for IoT Environments

The Internet of Things (IoT) has become a global sensory network that links physical and virtual objects by communicating and exploiting data and initiating physical actions. The evolution of this paradigm is already threatened by security issues, which constitute major risk factors that demand efficient solutions adapted to the IoT context. In this paper, we put forward a logical approach and systemic analysis that enables us to present the key aspects of new access control (AC) model for the IoT environments, called a pervasive-based access control model (PerBAC). Our approach is based on the study of important, reputable AC models that we use as a background for our proposed model. PerBAC is defined here based on a representation of the decision-making algorithm, a description of the abstract entities using the attributes as a fundamental concept and the collaboration aspects necessary to handle the case of multiple organizations. These attributes are the perfect recipient of the information collected by IoT environments from the physical world and allow optimal access control decisions to be taken according to dynamic rules and entities based on the algorithm. Our interpretation of the attributes, the dynamic entities and their exploitation by our proposed algorithm produce a new AC model adapted to the IoT paradigm.
