With how powerful the modern cpus have become. A normal person can buy Ryzen cpu with 90 cores. It's probably very easy to crack. I used to random guess 8key password's with dual core.
I would probably buy something like kill a wat but we don't have them here. I'm going to measure the power consumption by using phones to play YouTube until death. Then compare it to wpa2. Indirectly
It is not even close to as simple as you think. The actual passwords/key are never actually send over the network. They send message encrypted with the key over the network. It still takes many years to crack simple passwords.
Again WPA2 and WPA3 are not used to encrypt the actual data.
They only encrypt the process of exchanging the keys used by the actual data encryption. The actual data encryption method is exactly the same.
So you are trying to measure some difference in power for something that happens in a tiny fraction of a second and then is never done again until the device disconnects.
The actual encryption of the rest of the data is exactly the same no matter which method you used to choose the keys.
