Hi Sreenivasulu,

signed driver
----------------

A signed driver is a device driver that includes a digital signature. A digital signature is an electronic security mark
that can indicate the publisher of the software, as well as whether someone has changed the original contents of the driver package. If a driver has been signed by a publisher that has verified its identity with a certification authority,
you can be confident that the driver actually comes from that publisher and hasn't been altered.
Windows will alert you with one of the following messages if a driver is not signed, was signed by a publisher that has not verified its identity with a certification authority, or has been altered since it was released:

1)Windows can't verify the publisher of this driver

This driver either doesn't have a digital signature, or it has been signed with a digital signature that was not verified by a certification authority. You should only install this driver if you obtained it from an original manufacturer's disc or
from your system administrator.

2)This driver has been altered

This driver was altered after it was digitally signed by a verified publisher. The package may have been altered to
include malicious software that could harm your computer or steal information. In rare cases, legitimate publishers do alter driver packages after they have been digitally signed. You should only install an altered driver if you obtained it from an original manufacturer's disc.

3)Windows cannot install this driver

A driver that lacks a valid digital signature, or that was altered after it was signed, can't be installed on x64-based
versions of Windows. As a result, you will only see this message if you are running an x64-based version of Windows.

Unsigned Driver
--------------------

An "unsigned" driver is one that has NOT been tested, approved, or have an electronic signature placed on it by its
manufature.

U can verify whether the driver is signed or unsigned using the windows inbuilt tool sigverif.exe by running it on command line.
