Abstract
Method and an apparatus for ensuring protection of digital data are provided. Embodiments may include double re-encrypting decrypted data using multiple keys (e.g., an unchangeable key, and a changeable key). In various embodiments, the re-encrypting may be performed using hardware, software, or a combination of hardware and software (e.g., re-encrypting in hardware using an unchangeable key and re-encrypting in software using a changeable key). In some embodiments, encryption/decryption is performed with RTOS using a HAL and a device driver (e.g., a filter driver, a disk driver and a network driver, in an I/O manager).
