A Novel Classified Ledger Framework for Data Flow Protection in AIoT Networks

Abstract

The edge computing node plays an important role in the evolution of the artificial intelligence-empowered Internet of things (AIoTs) that converge sensing, communication, and computing to enhance wireless ubiquitous connectivity, data acquisition, and analysis capabilities. With full connectivity, the issue of data security in the new cloud-edge-terminal network hierarchy of AIoTs comes to the fore, for which blockchain technology is considered as a potential solution. Nevertheless, existing schemes cannot be applied to the resource-constrained and heterogeneous IoTs. In this paper, we consider the blockchain design for the AIoTs and propose a novel classified ledger framework based on lightweight blockchain (CLF-LB) that separates and stores data rights at the source and enables a thorough data flow protection in the open and heterogeneous network environment of AIoT. In particular, CLF-LB divides the network into five functional layers for optimal adaptation to AIoTs applications, wherein an intelligent collaboration mechanism is also proposed to enhance the across-layer operation. Unlike traditional full-function blockchain models, our framework includes novel technical modules, such as block regenesis, iterative reinforcement of proof-of-work, and efficient chain uploading via the system-on-chip system, which are carefully designed to fit the cloud-edge-terminal hierarchy in AIoTs networks. Comprehensive experimental results are provided to validate the advantages of the proposed CLF-LB, showing its potentials to address the secrecy issues of data storage and sharing in AIoTs networks.

Enabling machine learning‐based side‐chaining for improving QoS in blockchain‐powered IoT networks

“…Han et al 28 designed a blockchain for the artificial intelligence‐empowered Internet of things (AIoTs) and introduced a new method classified ledger framework on the basis of the lightweight blockchain (CLF‐LB). It divides and saves data rights at the source and makes complete protection of the data flow in the AIoT environment.…”

“…BDDT 27 overcomes the data utilization and trust issues caused due to IoT and provides high security but it takes more time for completing the transaction. CLF‐LB 28 reduces energy consumption and provides blockchain for data flow protection but it suffers from scalability issues. Logisticschain 29 reduces computational overheads and makes the blockchain decentralization but sometimes it becomes inefficient.…”
