Abstract

Security for Internet of Things requires balancing power consumption and memory usage in devices. In this work, we propose symmetric DICE-based schemes for distributed IoT systems, which aims to have effective security and recovery procedures through symmetric keys while achieving energy efficiency. Our security schemes utilize an efficient security primitive for IoT Device Identifier Composition Engine (DICE). Our schemes enhance security and flexibility in distributed IoT systems, allowing for a secure dynamic bootstrapping and a node recovery mechanism in IoT system.
