摘要： System, method, computer program product embodiments and combinations and sub-combinations thereof for protection of encryption keys in a database are described herein. An embodiment includes a master key and a dual master key, both of which are used to encrypt encryption keys in a database. To access encrypted data, the master key and dual master key must be supplied to a database server by two separate entities, thus requiring dual control of the master and dual master keys. Furthermore, passwords for the master and dual master keys must be supplied separately and independently, thus requiring split knowledge to access the master and dual master keys. In another embodiment, a master key and a key encryption key derived from a user password is used for dual control. An embodiment also includes supplying the secrets for the master key and dual master key through server-private files.
摘要翻译：这里描述了用于保护数据库中的加密密钥的系统，方法，计算机程序产品实施例及其组合和子组合。一个实施例包括主密钥和双主密钥，它们都用于加密数据库中的加密密钥。要访问加密数据，主密钥和双主密钥必须由两个单独的实体提供给数据库服务器，因此需要双重控制主密钥和双主密钥。此外，主主密钥和双主密钥的密码必须单独和独立提供，因此需要拆分知识以访问主密钥和双主密钥。在另一个实施例中，将主密钥和从用户密码导出的密钥加密密钥用于双重控制。实施例还包括通过服务器专用文件提供主密钥和双主密钥的秘密。
