- throw0101a 5y agoI would think that the encryption would prevent replay.

- sudosysgen 5y agoNaive replay attacks of course won't spoof because of encryption. However, by replaying, it will be harder for the receiver to find the actual good signal amongst masses of inauthentic ones. If you want to spoof via replay you need to do it subtly and progressively - think by only a few ms, and it only works for a specific target. But that's not what I'm talking about here.
