I believe the folks at Qualcomm do a lot with TrustZones too (from past talks with a couple of their engineers and cryptographers). I don't konw what exactly they do, though.
I imagine the folks at BlackBerry use it as an integral part of their security posture, too. But I don't recall any reading on it. > As a side note I would really love to see some full support for > TrustZone within the AOSP (I'd prefer a full open source > implementation and not something sticking in the closed Google Play > Services stack). +1 I think the technology needs to be licensed, and I believe that costs money. That might explain why the lower end phones don't use it. (I could be wrong about the licensing costs).
