Title:
Performance of DTLS with Connection ID in Narrowband IoT Networks
Biography:
Johann Zuerner is a recent graduate in Computer Science from Hochschule Bonn-Rhein-Sieg (HBRS). In his bachelor’s thesis he focused on secure and efficient communication in constrained network environments. He explored DTLS with Connection ID in cellular NB-IoT networks, combining theoretical analysis with hands-on performance measurements. The work included evaluating DTLS handshake duration and current consumption on embedded hardware such as the Nordic nRF9160 DK.
Abstract:
Connection ID is an extension in Datagram Transport Layer Security (DTLS) that helps maintain session continuity when IP addresses or ports change – common in constrained networks like Narrowband-IoT. Without Connection ID, a new DTLS handshake is required whenever an IP address changes.
In this talk, I present performance results of using Connection ID in DTLS over NB-IoT. The analysis includes measuring handshake duration and current consumption on embedded hardware such as the Nordic nRF9160 DK.
The presentation will also include a live demonstration measuring the impact of IP address changes on session continuity and resource usage.
