Could the 256^3 presets not be pre-calculated? It's not like the intent for these keys is to make them private and secure, so reusing the same key material except for the MAC address itself shouldn't be a problem, should it?
Also, 16777216 possibilities really aren't that many these days. With six cores at approximately 3.5GHz, assuming verification costs about 1000 instructions per key, brute-forcing every possibility will take between 4 and 5 seconds at most (half that on average). With appropriate rainbow tables, I think that should be feasible?
- dmitrygr 2y agoThe problem is not pre-calculation. The problem is that because you don’t know your MAC address, you need to broadcast all of those things, since you don’t know which one will be valid. Either at once or sequentially. Either way, iOS will not let you set up that much broadcasting.
