摘要： A method of authenticating a memory device by a host device, wherein the memory device, a memory device controller, a memory card containing the memory device and the controller, and the host device are manufactured by a memory device manufacturer, a controller manufacturer, a memory card manufacturer, and a host device manufacturer, respectively. The memory device comprises a first area, a second area for storing key index information, which is written by the memory device manufacturer before shipping the memory device, and a third area for storing a set of encrypted keys whose index corresponds to the key index information, which is written by the memory device manufacturer before shipping the memory device. After the memory device is shipped, the first area is not readable or writable by the controller, the second area readable but not writable by the controller, and the third area readable and writable by the controller.
