Abstract

Problem Solved By This Invention: External Device Bay (EDB) allows for a rack of 1394/USB drives to be connected to external systems through a device bay connector. This provides for the next generation of SCSI-type drive towers while also providing the same SCSI-type security problems. The main problem is how do you prevent unauthorized users from connecting to the EDB drive tower and accessing vital company data.

Power Up Security for External Device Bay

   Problem Solved By This Invention:

   External Device Bay (EDB) allows for a rack of 1394/USB
drives to be connected to external systems through a device bay
connector.  This provides for the next generation of SCSI-type drive
towers while also providing the same SCSI-type security problems.
The main problem is how do you prevent unauthorized users from
connecting to the EDB drive tower and accessing vital company data.

   Description of Invention:

   This invention provides for a keyboard password to be
entered before powering up the EDB.  There are two parts of this
security system: rerouting the keyboard controller to the USB and the
EDB power up mechanism.

   The first part of the invention that will be discussed
is the rerouting of the keyboard controller.  When the EDB is
connected to the host system, a USB connection event will
occur.   A USB aware operating system such as Windows 98 or
Windows NT will detect the USB connection, decode the connection as
belonging to an EDB and route that to the EDB USB device driver.  The
device driver will modify the USB host controller to generate
interrupts on every port 60/64 access (this feature is currently
available in Intel's Piix3, Piix4 and successor chipsets).  The port
60/64 accesses will be routed to this device driver who will then
send the data along the USB to the EDB.

   The other part of the invention is the additional hardware
added to the external devic...
