Disclosed is a secure method for authenticating a storage controller to an attached storage device, such that the device will only accept requests from an authenticated controller. A typical request would update functional characteristics of the device (such as device model number or serial number, customized firmware, support for vendor-unique commands, etc.). The authentication process uses nontrivial pseudo-random numbers and polynomial equations communicated in a series of commands between the controller and device.
