I think you misread the GP. Your definition of DRM is exactly what GP described as his use of the TPM.
>>I sell a device. There are lots of them in hands. You still aren’t getting my device key off of it. Yes, you can use that device all you like, but you aren’t going to clone it and make more.
What the GP describes is not safeguarding the nominal owner of the devices' keys. GP is restricting the nominal owner of the device on behalf of himself as the manufacturer. This is leveraging the TPM for DRM.
Other possible less nefarious uses of the TPM are irrelevant to this point.
- lxgr 3y agoOh, I indeed read that as "I [re]sell a device". In the case of them selling devices with embedded non-extractable keys, it could really be DRM. Or something else! Payment cards work like that – they hold keys that nobody is supposed to be able to duplicate; certainly not third-parties, but also not the legitimate account-/cardholder. There are plenty of uses for trusted computing other than DRM; they're just usually not as disruptive/frustrating to legitimate customers as DRM (and as a result are not as contentious), so they don't get as much attention.
