Dave, again please remove my identifying information. Thanks.
Based on this page it appears that the inflammatory claim you quoted
about embedding keys lacks any grounds, evidence or support. Donald
Whiteside's statement that "Intel did not embed DRM technologies
into the Pentium D and Intel 945 Express Chipset family" seems very
clear and unambiguous. As VP, Corporate Technology Group, he would
know, and he'd look pretty bad if it comes out with an embedded key
of the kind your anonymous source suggested.
Put up or shut up? Sounds fair. Read
http://www.dtcp.com/data/wp_spec.pdf , paying particular attention to
discussion of device certs and revocation. A "device cert" is a
certificate, signed by a central authority, stating that some
bitstring represents a key securely in the hardware of that device.
Or look at the statements from http://java.sys-con.com/read/46424.htm
, that each device has its own unique cert and key.
Or look at Digital 5, a member of some of the DTCP groups, referring
to it as DRM at http://www.digital5.com/news/press_122904.asp
Or look at the discussion of doing this outside the IEEE standards
process at http://java.sys-con.com/read/46424.htm . That site's
particularly interesting in its discussion of the controls they intend
to impose on even *unencumbered* data that enters your home. It also
discusses the fact taht each device has its own certificate and key.
Who's saying all this juicy stuff? A staff engineer with Intel, Steve
Bard.
And Intel's own statement on this said the 945 Express Chipset does
support DTCP-IP; they just called it Content Protection instead of
DRM. So I think it's pretty clear that DTCP is DRM, and that it is
in at least some Intel Chipsets (e.g. the 915 and 830). Given the
HD-video capability in the 945G Express, it seems quite unlikely that
there's no DTCP support in there.
