[Cryptography] Some (limited) info about Apple A7 security for fingerprints, keychains

[Jerry Leichter]

A level beyond marketing talk, but nowhere near technical detail.  Still a bit more than has been previously described.  Links to some perhap
http://www.quora.com/Apple-Secure-Enclave/What-is-Apple%E2%80%99s-new-Secure-Enclave-and-why-is-it-important

There's a link to an ARM site with a reasonable overview of the ARM TEE (Trusted Execution Environment) - which Apple's "Secure Enclave" may (or may not) be based on.  http://www.arm.com/products/processors/technologies/trustzone.php

Referring back to a point Perry made a while back:  TEE mode runs its own specialized "secure" OS.  That would seem to be an ideal target for verification....
