面向工业设备配置的双链协同验证安全机制OA

To address issues in industrial device configuration scenarios—such as insufficient granularity in identity authentication,disordered permission management,and low efficiency in operation auditing and traceability—this paper proposes a dual-chain collaborative verification security mechanism.By separating the recording of user information and configuration operation data,the mechanism constructs two distinct blockchains:a user information chain and a configuration operation data chain,thereby achieving decoupled management of permissions and behavioral auditing.The proposed mechanism adopts a consortium blockchain architecture and integrates dynamic key agreement,cross-node consensus verification,and bidirectional identity authentication technologies,effectively overcoming the scalability bottlenecks of traditional models in complex environments.Experimental results demonstrate that,compared with single-chain architectures,centralized models,and decentralized access control schemes,the proposed mechanism achieves a false positive rate of only 1.11%,representing a significant reduction of 4.67 percentage points compared to single-chain approaches.It also outperforms centralized models in configuration processing latency while maintaining extremely low storage overhead.Overall,the mechanism improves attack detection accuracy while satisfying the high real-time and high-security requirements of industrial configuration scenarios.
