Database security protocol design method and system supporting multiple privacy protection schemes

Abstract

The application discloses a database security protocol design method and system supporting a multi-privacy protection scheme, and belongs to the technical field of database security. The method comprises the following steps: a protocol initial module performs format checking on a database operation instruction and a security policy instruction issued by a user layer; a security protocol body module identifies all fields of the security policy instruction, and completes field analysis and encapsulation according to different instruction types; a security protocol header processing module encapsulates identity information of a sending party; a type configuration module queries type codes corresponding to different business meanings; a protocol assembling module assembles a security protocol header and a security protocol body; a protocol sending module sends the assembled security protocol to a privacy protection layer; and the privacy protection layer analyzes the assembled security protocol, and sends an analyzed database operation instruction to a database layer for execution. The application effectively meets the needs of different database products for different business scene privacy protection schemes, and has good scalability.
