摘　　要：针对工业物联网中共享数据的完整性和机密性问题,提出一种基于区块链的属性可撤销签密方案。构建工业物联网体系架构,在云雾架构中引入区块链网络;设计一种基于区块链的数据共享签密方案,利用超级账本中的Fabric-CA实现密钥生成和分发,将部分加解密和验证计算外包给雾节点;优化传统的签密算法利用雾节点实现属性撤销功能。安全性分析和实验结果表明,该方案实现了抵抗选择明文攻击、抗共谋攻击和恶意用户追踪等目标,具有较高的撤销效率。Aiming at the problems of the integrity and confidentiality of shared data in the industrial internet of things,the blockchain based signcryption scheme with attribute revocation was presented.A system architecture of the industrial internet of things was constructed,and the blockchain network was introduced into the architecture of fog and cloud computing.A blockchain based data sharing signcryption scheme was designed,the Fabric CA in hyperledger fabric was used for key generation and distribution,partial encryption,decryption and calculations were outsourced to fog nodes.The attribute revocation was implemented by optimizing traditional signcryption algorithms using fog node.The security analysis and experimental results show that this scheme achieves the security goals of resisting plaintext attacks,collusion attacks and malicious user tracking,with high revocation efficiency.
