【Abstract】The development of intelligent industrial Internet of Things has improved production efficiency, but at the same time, it has also put forward higher requirements for security protection. When data is shared between IoT devices, many systems use attribute-based encryption primitives to encrypt the data and upload it to the cloud. However, ABE will have the problem that it is difficult for a single user to revoke, the attribute will be leaked, and the privacy of users with the same attribute will also be leaked. In addition, the amount of data in IIoT is huge, and there will be bottlenecks in data storage. In this paper, we propose a blockchain and IPFSassisted puncturable-based anonymous traitor tracing scheme on the IIoT. The combination of blockchain and IPFS solves the problem of data storage, realizes the scalability of storage, the anonymity protects the privacy of users, and the puncturable encryption provides the dynamic revocation of users without affecting the normal decryption of this system by other users. Combined with traitor tracing technology, the malicious user who leaked the private key can be traced, and the user who leaked the data can be traced through the data access records on the blockchain, Security analysis shows that the scheme has IND-CPA security, Theoretical analysis and simulation results show that this scheme is superior to other schemes.
