Abstract: Various systems may benefit from interfaces for handling multiple types of inputs. For example, a device with a trigger input from an external device may benefit from an isolated logic level trigger that is capable of addressing multiple types and values of voltage. An apparatus can include an input configured to receive an external trigger input signal having a trigger input voltage. The apparatus can also include circuitry configured to automatically adjust the trigger input voltage to a value configured to be compatible with a provided attached system. A working range of the trigger input voltage can exceed a compatible working range of the provided attached system.

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: An instruction accelerator which includes an instruction source, and a single instruction multiple data array processor which executes the instructions supplied by the instruction source. A loop processor identifies all loop type instructions which are supplied by the instruction source, copies those instructions supplied by the instruction source into a loop memory, and supplies those loop instructions to the single instruction multiple data array processor in the order received, at the rate required by the single instruction multiple data array processor, and as many times as required by the loop count field.
