Imagine a future where you and your VPN connection maintain 10mbps of constant, uniform traffic at all times. That solves the problem too, if the noise is aways high, you can't see the signal
You can always see the signal in the noise, that is the point of the signal and therein lies the rub.
If ya do it right, you can't distinguish the signal from the noise. Encryption makes data look random. So if you send dummy random data then it just looks like constant random data. No signal is distinguishable.
Sure, but one of the benchmarks of a good cryptographic algorithm is to reduce the amount of meta information you can get from a random sampling. Most of the timing attacks are looking for traffic activity to pattern match ultimate source and receiver. If the encrypted tunnel is always exactly 10mbps of cryptographic traffic, then it would be much harder to identify
Yes as with almost everything the ability to do a thing is just a function of how much you want to do it.
