Q:

Blackberry QNX / Playbook encryption details

Now that Blackberry received FIPS 140-2 certification for one of it's QNX devices, does anyone have technical specifics on how data is encrypted on both mobile phones or the Playbook tablet? 
I'm interested in seeing the differences in how information is treated (technically) in the "Playbook" partition vs the "Enterprise" partition.  Is the same encryption used?  What keys are used?

A:

The FIPS 140-2 Security Policy for certificate 1578 is a public document which describes the cryptographic module in some detail, though perhaps not quite as you would like.
Section 3.2 of the security policy document describes the cryptographic algorithms in use and section 7 describes key management.
For more information on implementation details -- not for the Playbook or their QNX devices, mind you, but for their older phones or the Enterprise Server, you may want to check out the various technical documents in the "certification" part of their website.  As a Common Criteria evaluator, I would recommend reading the CC Security Targets and focus on the "TOE Summary Specification" which is a relatively high-level technical overview, but much lower-level than a simple hand-waving overview. The TOE Summary Spec in a CC Security Target is supposed to be able to allow you to imagine how things might be implemented.  For example, this Security Target has the TOE Summary Specification starting on page 50 which talks about some pretty interesting implementation-specific details.
