Yes. I've done a good 10 years of work in the field doing security
(mostly applied cryptography on embedded systems with a focus on side
channels like DPA, but also security concepts and threat/risk analysis)
and spent the last 3-4 years working on my PhD in the field of IT
security. My thesis is almost(tm) finished. I would claim to be an
expert, yes.

I must admit that I haven't seen your ideas in this thread?
