TZ in video decoders has little use other than content protection, and ARM is explicitly positioning it for use as such. While the article is certainly very hyperbolic, and many more steps will need to be taken before an annoying scenario of the type I described is likely to come to pass, I think it is a valid concern.
- tptacek 13y agoAny security feature in a video decoder is going to be designed for rightsholders. :) If you're concerned about content protection, the inevitability of hardware-assisted content protection as hardware security improves is a valid concern. But since TZ is (a) a technology with more non-DRM uses than DRM uses and (b) a fundamental part of the overall ARM architecture, not extending it to other ARM IP blocks would have been an odd choice. That's all I'm saying.
