摘　　要：针对当前工业数据共享存在中心化、监管困难和数据安全等问题,提出了一种在工业物联网环境下的安全、高效和可监管的数据共享方案。该方案引入监管机构来控制授权令牌发放,保证数据共享活动的可控性。结合门限代理重加密和区块链技术,将系统初始化和重加密任务分配给共识节点来完成,减轻系统计算开销。利用智能合约和零知识证明技术自动验证数据的有效性,保障了数据用户的权益。此外,高效的共识算法提高了区块链系统处理交易的速率。经安全性分析和性能分析表明,该方案在大规模工业数据共享场景中能更加安全高效地共享数据。Aiming at the existing problems of centralization,supervision difficulties and data security in industrial data sharing,a secure,efficient and regulated data sharing scheme in the environment of the industrial IoT is proposed.This scheme introduces a regulatory institution to control the issuance of authorized tokens to ensure the controllability of data-sharing activities.Combined with the threshold proxy re-encryption algorithm and blockchain technology,consensus nodes can handle system initialization and the re-encryption task to reduce system computing overhead.Smart contracts and the technology of zero-knowledge proof can automatically verify the validity of data to protect the rights and interests of data users,at the same time,efficient consensus algorithms can also increase the rate of transactions processed by the blockchain system.Finally,as the analyses of security and performance show,the scheme of this paper can realize data sharing more safely and efficiently in large-scale industrial data-sharing scenarios.
