    摘要: A disk apparatus is configured to be connected to a host device, and has a security program for preventing unauthorized user access to the disk apparatus. A disk medium stores a boot program for executing a boot process of the disk apparatus, and a security program storage device stores the security program. A processor is provided for retrieving the security program from the storage device and enabling the host device to execute the security program. The boot program is executed by the host device when the host device determines from executing the security system that the disk apparatus may be accessed by the user.

    摘要: A system-on-chip control system includes a processor for generating a root key for protecting data stored in a memory device connected to the control system, a root key storage unit for storing the root key, and a debug port configured to enable an external device to access the control system. The processor keeps the debug port locked to prevent the external device from accessing the control system if a root key is stored in the storage unit, and unlocks the debug port to enable the external device to access the control system after the root key is erased.
