Hi Hannes,
I agree that the example is a bit artificial and in real life
one would not use IKE/IPsec to control garage door.
At least now. But if IoT becomes ubiquitous then
who knows, probably such setup will be default
"off shelf" solution...

Valery.

P.S. What about mutual authentication in this case - please see my reply to original Yaron's message.

Hi Yaron,

if you further try to implement a prototype for a door opener then you
might run into a number of issues, such as

* how does the garage opener discover the garage door?
* what radio technology are you going to use?
* how does the garage door authorize the garage opener?

When you then answer all these questions you might realize (as I did)
that you neither want to use IPsec there nor even IP.

Ciao
Hannes

PS: I agree with your statement about mutual authentication.
