DATABASE ENCRYPTION APPARATUS FOR ENCRYPTION SCHEDULING OPTIMIZED FOR LARGE DATABASE AND OPERATING METHOD THEREOF

摘要

Disclosed are a database encryption apparatus and an operation method thereof capable of automating encryption scheduling optimized for a large-capacity database. A database encryption apparatus and an operation method thereof according to the present invention divide a plurality of data tables stored in a database into a master table and a slave table, distribute data tables divided into master tables to a plurality of encryption processing nodes, The data tables divided into the slave tables are dispersedly applied to the plurality of encryption processing nodes, and encryption processing is performed in parallel. When the data tables divided into the slave tables are encrypted, By providing a database automatic encryption scheduling technique that allows encrypted data to be used in the table as it is, it is possible to improve the encryption processing speed for a large-scale database and at the same time, the administrator does not need to directly perform encryption scheduling, It is possible to achieve a convenience character.
