Typically, the IoT device logs in on its own and sends data on its own. Consequently, authenticating the potentially billions of IoT devices to the server and among themselves becomes a big concern. Thus, securing distributed IoT networks requires verifying the authenticity of data and identities of devices. Since eID is normally used to describe the distinct and non-ambiguous properties and characteristics of a person, by analogy, we’ll use the name “Device eID (DeID)” to represent a unique, trusted and non-forgeable identity of a machine or device…
