Abstract
A method of establishing a group trust relationship in an Internet of Things (IoT) system using a first IoT device within a group of IoT devices is provided. The method includes generating, by the first IoT device, a first set of keys corresponding to the first IoT device, deriving, by the first IoT device, a group set of keys corresponding the group of IoT devices, and discarding the first set of keys and storing the group set of keys after the first IoT device transmits data toward a base station and goes idle, wherein the group set of keys is used by each IoT device within the group of IoT devices for subsequent transmissions of data to the base station.
