Abstract:

To enhance the network security capability of library information systems and ensure their safe and stable operation, we have conducted research on various network security issues, such as identity counterfeiting, data leakage, data tampering, data destruction, and difficult to trace important operations, and proposed practical and completely autonomous solutions and methods. These methods include data storage security for library information systems based on blockchain hierarchical storage, identity authentication, data encryption, data integrity, and operational authenticity and repudiation protection based on domestic commercial cryptographic technology. This study is crucial for the construction of a comprehensive and effective network security system for library information systems and the improvement of their network security capability.
