Ross Anderson of Cambridge University has published a lengthy and informative paper/FAQ on Palladium, the Trusted Computing Platform Alliance (TCPA), their relationship and their implications. His take is that Microsoft’s Palladium, soft-announced by the company earlier this week, will be built on TCPA hardware, adding some extra features as it goes along. Some of these features, he notes, will the there in order to make the package look more attractive, while some of the components of Palladium are already shipping in Xbox and WinXP. TCPA itself provides for a monitoring component to be included in future PCs. In phase one Anderson expects it to be an add-on chip on the motherboard, but further down the line it will be in the CPU.
