Microsoft's Palladium: What the heck is it?
Good FAQ on Palladium, a new security initiative by Microsoft. "Palladium is not a separate operating system. Rather, it consists of enhancements to the Windows kernel and to hardware, including the CPU, peripherals, and chipsets. Together, these enhancements will support a trustworthy execution subsystem within the PC--think of it as a very secure little computer inside your larger, insecure one."
