Hierarchical Trust Chain Framework for IoT Services
Hoan-Suk Choi, Gyu Myoung Lee, Woo-Seop Rhee · 2019
To support blockchain enabled Internet of Things (IoT) services, a lightweight approach is necessary in order to reduce the processing overhead and memory redundancy. We propose the hierarchical trust chain framework for secured and reliable IoT service provisioning, which consists of local trust chains and global distributed trust chain for scalable and trusted IoT services. The proposed framework provides the time slot based delayed verification algorithm and the blockchain configuration method based on the trust analysis mechanism.
