Screw this! I'm just gonna call M$ and tell them:
"Hello, this is Steve Douglas, I am from the encryption key checking department. I need to make sure your key is secure. Could you please email me the key so that we may run it through our systems?"
Then, after they email it, I would end the call with:
"By the way, is your refrigerator running?"
Comedy gold!
In all seriousness, there has got to be a back door to the 360...
An interesting concept, in hacking Nagravsion2 (Dish Network's most recent encryption venue), a perfect analogy was given to express how the security worked...it was like this:
Picture a house, inside the house is the data we need. The house has a front door, a back door (possibly) and a window. Even if you had a key to the house, you couldnt just walk right in, because there was a guard. So essentially what needs to be done is this, a distraction is carried out to keep the guard occupied, say a brick through the window, at that point you would attempt to enter through the back door, once inside the guard could do very little to stop you from getting what you wanted.
My point is this, with the 360 there is probably multiple levels of security (ie, doors and a guard). The best bet I see for exploiting this box is simultaneous attacks at most or all levels of its security, it will, eventually leave one layer exposed, then BAM, we're in like Flynn.
thoughts?
PS my concept was for exploiting the box itself, not the 2048 key, like most others have said, thats a lost cause.
