description In the current context of the wide application of Internet of Things (IoT) technology, cross-domain data sharing based on industrial IoT (IIoT) has become the key to maximizing data value, but it also faces many challenges. In response to the security and privacy issues in cross-domain data sharing, we proposed a cross-domain secure data sharing scheme (CDAS) based on multiple blockchains. The scheme first designs the cross-domain blockchain in layers and assists the device in completing the data sharing on the chain through the blockchain layer close to the edge device. In addition, we combine smart contract design to implement attribute-based access control (ABAC) and anonymous identity registration. This method simplifies device resource access by minimizing middleware confirmation, double-checking device access rights, and preventing redundant requests caused by illegal access attempts. Finally, in terms of data privacy and security, IPFS is used to store confidential data. In terms of ensuring data sharing security, searchable encryption (SE) is applied to the overall data sharing and improved. Users can find the required data by searching the ciphertext links in the blockchain system to ensure the secure transmission of private data. Compared with the traditional ABAC scheme, we have added modules for data privacy protection and anonymous authentication to further protect user data privacy. At the same time, compared with the access control scheme based on attribute encryption, our scheme has certain advantages in the time complexity calculation of key algorithms such as policy matching and encryption algorithm. At the same time, with the assistance of the edge blockchain layer, it can reduce the burden of limited computing resources of the device. This scheme can solve the security and efficiency problems of cross-domain data sharing in the industrial Internet of Things through security and experimental analysis.
