IEEE Project Abstract

Emerging network computing technologies extend the functionalities of industrial IoT (IIoT) terminals. However,this promising service-provisioning scheme encounters problems in un trusted and distributed IIoT scenarios because malicious service providers or clients may deny service provisions or usage for their own interests. Traditional non-repudiation solutions fade in IIoT environments due to requirements of trusted third parties or unacceptable overheads. Fortunately, the block chain revolution facilitates innovative solutions. In this paper, we propose a blockchain-based fair non-repudiation service provisioning scheme for IIoT scenarios in which the blockchain is used as a service publisher and an evidence recorder. Each service is separately delivered via on-chain and off-chain channels with mandatory evidence submissions for non-repudiation purpose.Moreover, a homomorphic-hash-based service verification method is designed that can function with mere on-chain evidence.And an impartial smart contract is implemented to resolve disputes. The security analysis demonstrates the dependability,and the evaluations reveal the effectiveness and efficiency.
