Protected Media Path

Och wann et net méi ganz aktuell ass, d’EFF huet e relativ interessante 4-deelege Bericht (1,2,3,4) iwwert d’WinHEC 2005. Virun allem geet et drëm wéi Microsoft sech d’Multimedia-Fähegkeeten (oder éischter d’Aschränkungen) vun zukünftege PCe virstellt.

Am interessantesten ass awer den 3. Deel, an deem et em de „Protected Media Path“ an em Driver Lockdown geet. Hei e pur Zitater:

PMP includes several phases and features which Microsoft plans to introduce over time. One such feature is COPP, which allows applications to selectively disable the use of particular video cards or particular outputs on a video card. (For example, an application could refuse to output to a DVI output without HDCP encryption, or to an analog VGA output, or to a YPbPr component video output.)
[…]
PMP will create a kernel-enforced construct called a Protected Environment (PE) in which particular software modules, including drivers and other code, that are trusted by particular entertainment companies can run and enforce DRM restrictions.
[…]
Components that are loaded into the PE by the Windows kernel must be signed and authenticated
[…]
Perhaps most significantly, the PE will be subject to a “global revocation list” maintained by Microsoft and distributed through Windows Update and possibly other channels.

Kee Wonner also dass sou laang um Windows Vista (a.k.a. Longhorn) gebastelt gëtt.
