“…There are several aspects of the IoT that present security problems, including IoT device communications, constrained resources (e.g., limited battery life), variety (e.g., different types of devices made by multiple manufacturers), and scale (billions of devices) [41]. Among the plethora of recent research solutions [5,15,24,27,39] for protecting IoT data, some related research (e.g., [15,24,32]) focuses on security and privacy preservation policies while others (e.g., [5,15,27,39]) focus on encryption frameworks for the IoT [28].…”
