Abstract
With the rapid development of information technology, Local Area Network (LAN) data security faces numerous challenges, and traditional storage solutions struggle to meet the escalating security requirements. This paper proposes a blockchain-based LAN data security storage scheme aimed at addressing issues such as data tampering, privacy leakage, and complex permission management inherent in existing storage models. By leveraging the decentralized nature, immutability, and cryptographic algorithms of blockchain technology, this scheme constructs a distributed ledger to ensure data integrity and consistency. Automated permission management is achieved through smart contracts, thereby optimizing access control mechanisms. Experimental results demonstrate that this approach not only maintains efficient data read and write operations but also significantly enhances data security and system reliability. Compared with traditional solutions, this study innovatively applies blockchain technology to the LAN environment, resolving single-point failure problems associated with centralized storage and achieving distributed secure data storage. Furthermore, by introducing lightweight consensus algorithms, computational overhead is reduced, and system performance is improved. Research findings indicate that this scheme not only strengthens data security but also provides new perspectives and technical support for data management in LAN environments, holding significant theoretical implications and practical value.
