Oh, oh... it's the "Trust us..." talk. ----- Original Message ----- From: "ee380" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, April 03, 2001 3:15 PM Subject: Jeff Lotspiech, IBM * Content Protection * W4:15 Gates B03 > > > Computer Systems Laboratory Colloquium > 4:15PM, Wednesday, April 4, 2001 > NEC Auditorium, Gates Computer Science Building B03 > > Title: Content Protection for Recordable Media > > Speaker: Jeffrey B. Lotspiech > IBM Almaden Research Center > > About the talk: > > Content Protection for Recordable Media, or CPRM, is a technology > developed by IBM, Intel, Matsushita, and Toshiba to provide copy > protection on portable media. The technology allows a recorder to > record encrypted content, and a player to play it back, without > having any keys in common. The media acts as a passive oracle to > allow the different boxes to come to the same cryptographic key. > In contrast, previous copy protection technologies like the one > used for DVD video, depended on shared keys between the mastering > studio and the players, with predictable results. As soon as a > 16-year-old in Norway found one shared key, the system was > effectively broken: there was no way to exclude the broken key > from the system without hurting too many innocent consumers. In > contrast, CPRM can survive thousands of independent attacks, and > exclude millions of circumvention devices, without any chance of > innocent consumers being affected. > > Recently, articles have appeared in the press that CPRM will be > standardized on all PC hard drives. This has fueled Orwellian > mages of a Big Brother chip on your PC that will decide whether > your files are worthy of being copied. This is complete nonsense. > CPRM would never be standardized, nor have we ever proposed such > a thing. CPRM strength is portability and interchangeability and > it is mismatch for fixed hard drive. It is completely passive, > requires no hardware, and can only be exploited by newly-designed > applications. It cannot possibly affect existing files or > applications. How these myths came about, and persist, was an > object lesson for a media-naive researcher. > > About the speaker: > > Jeff Lotspiech is the manager of the Content Protection > Technology Group at the IBM Almaden Research Center.
