Meeting notes from Seth Schoen who had a meeting with representatives from Microsoft discussing Palladium last Tuesday.
Palladium is distinct from TCPA and has technical differences from TCPA. It has some architectural points in common with TCPA, including, most significantly, the use of “trusted hardware” within a PC in order to establish a root of trust. Both TCPA and Palladium require modifications to existing PC hardware architecture in order to work. In addition, they both require modifications to software in order to use trust features. Both are intended to run existing “untrusted” software without any modifications.
