【Abstract】Industrial data plays a key role in the industrial internet, and its secure collection problem has been highly valued by researchers. As Industrial Internet of Things (IIoT) devices are geographically dispersed and difficult to link, blockchain technology is usually introduced to solve the security management problem of industrial data. Unfortunately, the IIoT device is not stable, and it may leave incorrect messages in the blockchain, which will be permanently stored with potentially catastrophic consequences. As an effective solution, the redactable blockchain technology can allow people to modify the data on the blockchain. However, the existing redactable blockchain cannot guarantee industrial data security in the industrial internet due to requirements of trusted third parties, large overheads or lack of accountability mechanism. In this paper, we propose a trustworthy industrial data management scheme based on redactable blockchain in the industrial internet. To avoid additional burdens on industrial blockchain systems, a double-blockchain architecture is established to separate trapdoor management transactions. Distributed chameleon hash parameter generation and trapdoor recovery methods can avoid the security problems faced by the centralized organization. The fault tolerant trapdoor recovery mechanism based on verifiable secret sharing technology as an alternative enhances the security of the system. The blockchain will record various information in the trapdoor management process and use it as evidence for accountability when disputes arise. The theoretical analysis and experiments show that the approach can effectively deal with malicious behaviors and has acceptable overhead. (C) 2021 Elsevier Inc. All rights reserved.
