Abstract
Internet of Everything (IoE) has emerged as a promising paradigm for
the purpose of connecting and exchanging data among physical objects and
humans over the Internet, and it can be widely applied in the fields of industry,
transportation, commerce, and education. Recently, the emergence of 6G-enabled
cybertwin network architecture provides the technical and theoretical foundation
for the realization of IoE paradigm. However, the IoE has three open issues in the
6G-enabled cybertwin architecture, i.e., data authenticity, data storage and node
reliability. To address these issues, we propose a blockchain-based decentralized
reputation management system (BC-DRMS) for IoE in 6G-enabled Cybertwin
architecture. In the proposed BC-DRMS, the traffic data collected from end nodes
is stored on the blockchain and the decentralized file system, i.e., InterPlanetary
File System (IPFS), to resist data tampering, and then the data is further processed
by the edge clouds and core clouds to provide services to users. Also, a multi-level
reputation evaluation scheme is designed to compute the reputation scores of IoE
nodes to prevent malicious node attacks. The experiment results and analysis
demonstrate that, compared to the traditional centralized reputation management
systems (CRMS), the proposed BC-DRMS cannot only address the issues of data
authenticity and storage, but also provides high reliability for IoE in 6G-enabled
cybertwin architecture.
