Firmware is securely downloaded from a host to an information storage device using an encryption key generated by the information storage device. The encryption key is generated in response to a firmware download request by the host. The host encrypts the firmware image with the encryption key and downloads the encrypted firmware image to the information storage device. The information storage device receives the encrypted firmware image, decrypts the firmware image, and updates its firmware with this firmware image.
