IoTChain: A Three-Tier Blockchain-based IoT Security Architecture
This addresses security challenges for IoT systems, but appears incremental as it builds on existing blockchain concepts.
The paper tackles IoT security by proposing IoTChain, a three-tier blockchain-based architecture, and demonstrates its utility through performance evaluation.
There has been increasing interest in the potential of blockchain in enhancing the security of devices and systems, such as Internet of Things (IoT). In this paper, we present a blockchain-based IoT security architecture, IoTchain. The three-tier architecture comprises an authentication layer, a blockchain layer and an application layer, and is designed to achieve identity authentication, access control, privacy protection, lightweight feature, regional node fault tolerance, denial-of-service resilience, and storage integrity. We also evaluate the performance of IoTchain to demonstrate its utility in an IoT deployment.
