draft-ietf-pkix-sim-00.txt : computing the VID

["Olle Mulmo" <mulmo@xxxxxxxxxx>]

While running other errands browsing the PKIX charter page, I discovered
and browsed draft-ietf-pkix-sim-00.txt.

The Virtual ID is defined as

        VID = hash( hash(ID, R) )

where R is some scrambling data (secret and/or random). How is this
different than

	VID2 = hash( hash(ID), R )

from a cryptographical point of view? VID2 seems to me to be more in line
with what I have seen in other RFCs (where ID is sensitive data, such as
a password).
