When the company was putting together the custom chips for Sony and Microsoft one of the big focuses was on how AMD could help the two console makers work through the scourge of modern times – software piracy.

The tool being used is called cryptographic isolation, something both the PS4 and Xbox One contain as something ensures “the game developer doesn’t have to trust the person who physically controls the box,” says AMD’s Forrest Norrod.

“Previous generations of the game consoles could be hacked,” Norrod says in an interview with CRN, “and so you could go down to probably any number of places within a 10-mile radius [and] buy a 4-terabyte hard drive [with] every PlayStation 3 game ever written on that hard drive.”
The feature was first introduced on the server side with the first-gen EPYC chips, as Secure Memory Encryption (SME) and for virtual machines as Secure Encrypted Virtualization (SEV). It uses a dedicated ARM co-processor embedded into the chip to isolate virtual machines from the hypervisor and from each other.

And SEV could ensure that Stadia becomes the most secure gaming platform ever made, and that could be a major feather in its cap when talking to publishers about exclusive titles…
