Proposed on Device Capability based Authentication using AES-GCM for Internet of Things (IoT)

Economics of scale in Internet of Things (IoT) presents new security challenges for ubiquitous devices in terms of authentication, addressing and embedded security. Currently available cryptographic techniques require further analysis to determine applicability to IoT. We introduce an authentication and encryption protocol which serves as a proof of concept for authenticating device using the Advanced Encryption Standard (AES) – Galois/ Counter Mode GCM as cryptographic primitive. Authenticated encryption is best suited concept for IoT that will provide both message encryption and authentication. Unique part of this work is a novel approach of extending authentication and encryption with cryptographic capabilities
