Okay I did not understand in the proper way these lines. Yes of course it introduces a security problem but for me that was a vulnerability in the 1.0.2 specification, and that is why I wanted to make an example of replay attack. So now I am curious to know how can you detect an out-of-band reset? I mean what would be the difference between this out-of-band reset and a “physical” reset on a node?
You are right I was thinking about this and I cannot figure out how the server could know if a device is reset in ABP. That is why the quotation given just before seems a little bit obscure to me … Yes this would be a terrible vulnerability in my network.
Therefore, I guess replay attack examples that I saw on the net were not implementing LoRaWAN specification correctly.
