Dwayne,

Yes, I think it does.  It becomes clear that the Vendor Specific Key is=20
both the T10 Vendor ID and the Vendor Specific Key Reference and that both =

will be used for the OOB method to get the key.

Thanks,

Kevin,
=20
My intention was the T10 Vendor ID + the Vendor Specific Key Reference as=20
a pair.
=20
Does the following change make this clearer?
=20
Replace=20
=20
If the KEY FORMAT field is 01h, the KEY field shall contain the T10 VENDOR =

INDENTIFICATION field, specified in ?T10 Vendor ID Based Designator=20
Format? section of SPC-4, followed immediately by a Vendor Specific Key=20
Reference identifying the Key to be used to encrypt or decrypt data.=20

with the following?
=20
If the KEY FORMAT field is 01h, the KEY field shall contain the=20
information shown in the following table.=20
=20
Table YX ? vendor specific key  reference elements:

00 ? 07
T10 vendor identification, this element of the KEY field is provided to=20
associate the key reference to a specific vendor.
08 ? n
vendor specific key reference, this element of the KEY field identifies=20
the Key to be used by the device server to encrypt or decrypt data
=20
See SPC-4 for a description of the T10 vendor identification field=20
element.
=20
If this looks OK to you I will revise my proposal one more time before=20
Paul incorporates it into 05-446

I was concerned about the vagueness of what is used as the reference to be =

used in a vendor specific manner.  Is it both the T10 Vendor ID + the=20
Vendor Specific Key Reference as a pair, or only the Vendor Specific Key=20
Reference.=20

I thought there was supposed to be some text about how the T10 vendor ID=20
is used.  More specifically, is the T10 Vendor ID supposed to be part of=20
the reference value used to get the key or not.=20
