@GSMD: Thanks for weighing in!

Question: Doesn't the x86 support the same hardware root of trust the Trusted Computing Group nspecified and ARM Trustzone implmewnts in its own way?

Quark is 32-bit Pentium based ISA with single Core, single Thread.

Getting better opportunities on the security and embedded internet stack because of very long stay in the computing environment will be a very good plus point for Intel on getting proven in IoT Processor segment.

GSMD , very interesting post.


Could you please tell a bit about where mcaffee security is relative to to other software stacks?

The reasoning by Daikin is a load of nonsense. Freescale ARM and Power products are the only mass market processors and controllers available with tamper detect, secure boot, flips 140-3 grade security and in certain products side channel analysis production. maxim and a few others make parts but no support across the entire range. I just finished design of a tablet ref design for mil grade security and only the Freescale I.mx6 cut it. granted the Mcafee stack helps but security 101 says that the root of trust begins in hw. Add to all this arm's Trustzone really hels secure os partitioning. In summary, it looks to be a poor technical decision. Note, am not a Freescale employee or contractor. just a security researcher .

Of course you can be secure with other CPU, too. As an example, why is ARM used inside chip+PIN card reader ?

I do not want to say using Quark was a bad decision, just that public justification may differ from actual one.

At least according to a few software engineers I asked about this subject, symantec and wind river doesn't offer something unique security-related. It's mostly branding. I wonder if this is the only benefit for this chip, or are there others planned?

Chatting with fave analysts Kevin Krewell and David Kanter in the IDF media room I realize Quark must be 32 bit. There's just no need for 64-bit addressing in IoT for a loooooong time.
