Show Me Your Security Blueprint

It seems the security aspects of wireless networking finally start becoming important to the market. I have had multiple discussions with multiple customers about that recently. 

And honestly - it has been very bad almost everywhere. Everywhere except the official Bluetooth mesh, where the security architecture is at another level. There is a good overview published by Bluetooth SIG back in 2017, and for those who are willing to dive deeper, there are the specifications - both adopted and the upcoming drafts.

But without diving into the details, there is one fundamental question any customer concerned about the security of a wireless system should ask: show me the blueprint, show me how you have architected that and how it works.

Vendors can claim anything, but the claims practically cannot be verified. So if they claim their security is good, they should not have any issue providing openly the architecture of their system. Any excuse to do that should be a warning, or even a red stop light. Meaning they have something to hide.
