He's a troll.

iPhones don't use it. They don't use Qualcomm SOC's.

Note that TrustZone is not a Qualcomm technology, but rather an ARM technology. Apple could have gone with TrustZone in their SOC.

(But yes, he is a troll and this whole case has nothing to do with Apple).

Nit: TrustZone isn't a Qualcomm technology, but KeyMaster is Qualcomm software built on top of it (and that appears to be where this break lies).

>iPhones

nah

Apologies to the uninformed downvoters :(

TrustZone is an ARM thing, and the iPhone Secure Enclave is indeed built on TrustZone.

Apple do not use Qualcomm and this a Qualcomm-specific bug. But Apple do use their own modded TrustZone.

http://www.apple.com/business/docs/iOS_Security_Guide.pdf page 7.

Despite widespread rumour to the contrary, the secure enclave on iPhones is a separate core, not just TrustZone on the main CPU.

Apologies, I stand corrected. All I've ever heard is it being explained as Apple's implementation of TrustZone, which conceivably could be modded so far as to be put on a separate coprocessor.
