Abstract
This is the author accepted manuscript. The final version is available from IEEE via the DOI in this recordData availability statement: The [code] data used to support the findings of this study have been deposited in the [IEEE DATAPORT] repository ([10.21227/rtmq-t937]).Internet-of-Things (IoT) are increasingly operating in the zero-trust environments where any devices and systems may be compromised and hence untrusted. In addition, data collected by and sent from IoT devices may be shared with edge computing systems in order to reduce the reliance on centralized (cloud) servers, leading to further security and privacy issues. To cope with these challenges, this paper proposes an innovative blockchain-enabled information sharing solution in zero-trust context to guarantee anonymity yet entity authentication, data privacy yet data trustworthiness, and participant stimulation yet fairness. This new solution is able to support filtering of fabricated information through smart contracts, effective voting, and consensus mechanisms, which can prevent unauthenticated participants from sharing garbage information. We also prove the proposed solution is secure in the universal composability framework, and further evaluate its performance over an ETH-based platform to demonstrate its utility.Foundation of Yunnan Key Laboratory of Blockchain Application TechnologyNational Natural Science Foundation of ChinaProvincial Key Research and Development Program of HubeiFoundation of Henan Key Laboratory of Network Cryptography TechnologyFoundation of Hubei Key Laboratory of Intelligent Geo-Information Processin
