Mobility-Enabled Authentication Scheme for IoT Architecture

In Internet of Things (IoT) system architectures where static and mobile IoT devices connected to gateway devices for forwarding and processing their collected data, authentication and secure communication between IoT device and gateways are crucial requirements. This paper proposes a mobility-enabled DTLS-based authentication scheme. It maintains mutual secure authentication between an IoT device and a gateway while transferring the connection between the visited gateways. We propose a scheme that implements a session resumption procedure to allow the authentication between a moving IoT device and a visited gateway. The performance of the proposed scheme is evaluated in terms of handshake time, processing time, energy consumption, and memory overhead. The results demonstrate its feasibility for limited resource devices.
