Abstract: Various security systems in which secure data is to be transferred to an authenticated device may benefit from methods of securing such data transfer. For example, certain secure drives or other memory devices may benefit from the prevention of covert access after successful completion of an authentication process. A method can include monitoring for a loss-of-link condition for a link associated with a successfully executed authentication operation. The method can also include determining that the link has been lost. The method can further include taking a security response based on the determination that the link has been lost.

Abstract: Various storage devices may benefit from encryption technologies. For example, storage devices may benefit from systems and methods for a fully isolated encryption key filling port. A system can, for example, include a host connector installed in a host computer and configured to connect to a storage connector in a storage device. The system can also include a key fill device connected to the host connector. The key fill device may be configured to communicate data to the storage device via one or more pins in the host connector. The host computer may be configured to not use the one or more pins as data pins.

Abstract: Various devices may benefit from enhanced security. For example, secure storage devices and authentication devices may benefit from security that permits isolation of the devices from the operating system and data ports of a host computer. An apparatus can include a first interface configured to connect to a non-volatile storage device. The apparatus can also include circuitry configured to supply an encryption key over the first interface to decrypt data on the non-volatile storage device. The first interface is configured to connect directly to the non-volatile storage device.

Abstract: A storage system controller (302) includes a plurality of media controllers (301), a local microprocessor (306), and a host interface logic (310), operably coupled by a multi-drop bus. The multi-drop bus includes a control bus (324), a payload data bus (320), a real-time ready-status (data ready) signaling bus (322) and a general microprocessor bus (330). Each media controller has a storage media (311) operably coupled thereto. Each media controller includes a parameter storage (404), a media interface circuit (406), a control data state machine (408), a command sequencer state machine (410), a media-side multi-mode transfer state machine (412), a dual-port memory (402), a memory controller (420), and a host-side transfer state machine (430). The host interface logic and the media controllers are implemented in one or more Field Programmable Gate Arrays.

Abstract: A pair of hard drives are slidably mounted upon a mounting displaced from an underlying printed circuit board secured to a base. The mounting includes a centrally located aperture beneath each hard drive to expose the underside of the hard drive to a cooling air flow flowing between the mounting and the printed circuit board. Rails, secured to the underside of each hard drive, slidably engage corresponding grooves in a respective section of the mounting and a locking bolt is used to secure a rail of the hard drive with the mounting. A ribbon cable having connectors at opposed ends interconnects each hard drive with the printed circuit board and the respective section of the mounting may include a tab to maintain the connector of the ribbon cable in engagement with a corresponding connector on the printed circuit board.

Abstract: Each of one or more devices to be detachably attached to a mechanical substructure includes rails on opposed sides with insertion/extraction mechanisms. Each of a plurality of pairs of guides mounted on the substructure slidably receives and retains a respective set of rails upon attachment of the devices. The insertion/extraction mechanism includes one or more pivotable handles associated with each device for retaining the device with the substructure. A spring extending from a rail makes electrical contact with electrostatic discharge ground pads on the substructure to discharge existing static charge from the device prior to electrical engagement between an electrical connector on the device and an electrical connector on the substructure. An apertured plate of the substructure includes a plurality of apertures through which the devices are inserted/extracted.

Abstract: A device to be detachably attached to a mechanical substructure includes rails on opposed sides joined at the front by a cross member. A pair of guides mounted on the substructure slidably receives and retains the rails upon attachment of the device. An alignment pin extending from a rail mates with a hole in one of the guides to insure alignment of an electrical connector of the device with an electrical connector mounted on the substructure. The cross member includes screws for securing the cross member to the substructure. A spring extending from a rail makes electrical contact with an adjacent guide and an electrostatic discharge contact plate to discharge any existing static charge.
