I was going to add a couple if ideas, untill I saw this... I do not think you can, legally and/or ethically, do "usage rights verification" with open-source software.

6

Because I developed a control program just to avoid pretending to be an administrator.

Sorry, but I do not understand what you mean with this...

You can check the hash of the following files:

/etc/dropbear/dropbear_*_host_key
/etc/uhttpd.*
/etc/urandom.seed

A person that goes out of their way to install OpenWrt on their device is not the kind of person that takes kindly to DRM in all of its forms, even if you can somehow make this work without bypasses.

Now it's possible there's a language barrier and you don't actually mean digital rights management, but simply "device authentication" so your routing setup works. In that case you would just generate whatever secret keys you need and provision them to their respective devices, and any hardware IDs would just be for identification.
