FBI – Featherlight Blockchain for IoT (NSoE)

Blockchains provide several interesting features, for example, decentralisation, immutability, non-repudiation, accountability, availability, and transparency. Some of these are compelling to use in an IoT context, namely to ensure and decentralise trust in the IoT infrastructure. We propose to design and build a Featherlight Blockchain Infrastructure (FBI) that will serve as a trust anchor for IoT devices. The smart contracts, consensus protocol, and identity and access management of the FBI will be tailored towards IoT services, particularly Advanced Metering Infrastructures. We will identity and make appropriate trade-offs between security and performance of the blockchain infrastructure. We will focus on three case studies to demonstrate how FBI helps with data security, recovery, and anomaly detection: Secure Logging, Secure Timestamping, and Secure Firmware Updates. To achieve this, we will interface the FBI with real-world IoT devices in the Critical Infrastructure labs of iTrust.
