CORECONF Implementation as SDN Southbound Interface for IoT: An OSCORE/EDHOC Use Case
Javier A. Fernandez, Rafael Marín-López, Gabriel López Millán, Laurent Toutain · 2025
The Internet of Things (IoT) aims to gather valuable data from our surroundings through resource-constrained networks and devices. For this reason, efficient and lightweight communication protocols are required to be developed and adopted. CORECONF, a network management protocol designed for constrained environments, provides a promising solution for IoT device configuration. This work introduces pycoreconf, an open-source implementation of CORECONF, with the goal of testing the protocol and making it more accessible to researchers and developers by enabling its use in real-world scenarios and experimental setups. In this paper, we evaluate its performance and applicability as a southbound interface in an SDN-based architecture, demonstrating its potential for configuring security contexts between IoT devices. Potential for other use cases remains to be explored in future work. Our results suggest that pycoreconf is a viable tool for those interested in exploring and adonting CORECONF in IoT scenarios.
