Research on the Application of Database Security Technology in the Domestic Transformation of Mobile Field

With the rapid development of information technology and the implementation of the national information security strategy, the importance of domestic databases in critical information infrastructure has become increasingly prominent. The purpose of this paper is to explore the security technology of domestic database, pay special attention to the security characteristics of KingbaseES (KES) database, as well as use identification and transparent data encryption based on national secret algorithm to solve the security risks exposed in the process of localization of China mobile database system. By analyzing KES's technological innovations in identity authentication, data integrity protection, tamper-proofing, encryption, auditing, etc., this paper reveals the advantages of domestic databases in terms of security, and verifies their application effects in scenarios with high security requirements through actual cases. Finally, this paper puts forward the development direction of domestic database security technology in the future, and predicts the possible new technologies and new trends, so as to escort the development of digital economy.
