“…In their work, a hierarchy of local and global smart contract was developed to perform the permission delegation and access control, which resists illegal delegations and preserves the user privacy at the same time. This master-slave hierarchical structure has also been used to construct cross-domain trust access mechanisms [28] for power terminals, and improve the efficiency and data credibility for cross-domain IoT authentication [15]. In addition, Wang et al [29] leveraged undirected graph to build authentication relationships for IIoT devices.…”

Industrial Internet of Things (IIoT) has emerged as a prospective technology that improves the productivity and automation level for industrial applications. Devices from cooperative IIoT domains will communicate and collaborate on the increasingly complicated manufacturing tasks. To secure cross-domain device collaborations, we propose combining the blockchain with multi-factor authentication. Because the multifactor authentication conforms to IIoT devices' operation modes and brings higher security levels, and the blockchain technology contributes to building trust among different domains. However, this combined usage still has limitations in terms of the potential loss of factor attack, the storage overhead on the blockchain, and the contradiction between efficiency and privacy preservation. Motivated by these facts, in this paper, we develop a privacypreserving blockchain-based multi-factor device authentication protocol for cross-domain IIoT. Specifically, multiple factors are additionally encoded by the hardware fingerprint into random numbers, before being transformed into key materials. The blockchain only stores each domain's dynamic accumulator, which accumulates derived key materials for devices, thereby reducing the overhead. Moreover, the on-chain accumulator is leveraged to efficiently verify the unlinkable identities of crossdomain IIoT devices. The security of our protocol is formally proved, and the security features and functionalities are respectively discussed. A proof-of-concept prototype was implemented to prove the efficiency and reliability. The comparison results indicate that the on-chain storage is greatly reduced. Finally, the smart contract's performance was evaluated to show scalability.
