Does Ryzen use an ARM Core(s) for security?

In reference to this article about AMD APUs.


I'm quite interested as to whether or not Ryzen chips use this kind of security. I thought the APU chip with an ARM core for security purpose was brilliant. In all my reading, I haven't yet seen anything like it. Does Ryzen have any AMD/ARM-specific security implementations? Does anybody have anything on the security of the chip itself?


Thanks ahead of time for any info.
