| 摘要 |
An apparatus and method for operating a relational database (DB) are provided. The method includes determining a sensitivity classification for a column of a table in the DB, performing encryption, using a data encryption key (DEK), of sensitive data when writing the sensitive data to the column determined to be sensitive, performing decryption, using the DEK, of the encrypted sensitive data when reading the sensitive data from the column determined to be sensitive, and performing writing to the column and reading from the column of unencrypted non-sensitive data when the column is determined to be non-sensitive. |
