More Information
Summary:This invention provides an expandable confidential key management system, which proposes an effective and safe key management system implementation architecture by using a master-slave architecture to save keys and confidential data in a hardware password module and distribute derivative keys as the basis for encrypted transmission. The system comprises a central control module and a secondary password module. The central control module manages the authority of the secondary password module, the process for accessing the key and the confidential data, and encryption of saved data. The secondary password module stores the key and the confidential data, so as to eliminate the steps of requiring encrypted storage for placing the data in the database. The secondary password module can be expanded if necessary, and the expandability allows setup of a proper amount of modules according to different system needs, allowing clear division of control and storage to effectively manage the key.
