The Industrial Internet of Things (IIoT) enhances smart manufacturing process that escalates productivity through revolutionary techniques. The manufacturing process is sophisticated and complex because of various IoT domains (e.g. industries). A final product is an outcome of the efforts of several departments from different industries. However, this raises the cross-domain communication's privacy and security issues. Cross-domain data sharing for product manufacturing is a challenging research direction. This paper proposes a centralized cloud-based cross-domain data sharing platform using multiple security gateways. The security gateways use the blockchain to store the information into the centralized cloud. Once the application reported a malicious activity, the centralized cloud verifies the concern from the blockchain. Further, an action is taken against the party that performs malicious activity in the security gateways. The algorithms are designed for authentication and transaction of data. The proposed framework is able the secure data movement among different domains globally. The experiment result demonstrates that the proposed security and privacy framework helps to maintain trust among the industries that collaborate on manufacturing across the domains.

工业物联网 (IIoT) 增强了智能制造过程，通过革命性技术提高了生产力。由于各种物联网领域（例如工业），制造过程复杂而复杂。最终产品是来自不同行业的多个部门努力的结果。然而，这引发了跨域通信的隐私和安全问题。产品制造的跨域数据共享是一个具有挑战性的研究方向。本文提出了一个使用多个安全网关的集中式基于云的跨域数据共享平台。安全网关使用区块链将信息存储到集中式云中。一旦应用程序报告了恶意活动，集中式云就会验证来自区块链的关注。更多，对在安全网关中执行恶意活动的一方采取行动。这些算法是为数据的身份验证和交易而设计的。所提出的框架能够在全球不同域之间安全地移动数据。实验结果表明，所提出的安全和隐私框架有助于维持跨领域制造协作的行业之间的信任。
