Aiming at the problems of the integrity and confidentiality of shared data in the industrial internet of things,the block-chain 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 block-chain 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 imple-mented 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.
