I was under the impression every PS3 had its own unique set of "keys." Is that wrong, and these keys are the same ones in every PS3?

yes the keys are different
there are public keys(same all over) and private keys(unique to each console
but the hackers have public keys and know how to get private keys.
sony can still fix it if they change all the private keys by firmware update
|
Not true at all.
The private keys are stored in Sony headquarters and used to sign all the code that runs on the PS3 (games, netflix, psn titles, firmware updates, ect.) The private keys are on every PS3, but are supposed to be impossible to find as they normally are exposed only in a protected SPU.
Because of an exploit, the public keys could be pulled out of the console. And because Sony used the same number over and over for the nonce, instead of a random number, figuring out the private key was only a matter of algebra.

go check again

He's right. Sony can't fix it by firmware without rendering useless everything released on the PS3 so far.
|
when did i say sony can?
but if they retrieve all the private keys,they still can with a firmware upgrade,that way they will change the way of verify and calculation of keys
|
Retrieving every single key released so far on games and DLC, patching it so only these ones are legit and locking away the rest would be a monumental task, and then probably a upgrade in the GBs...
Not to mention a try to fix it could render new and old games alkike unplayable even in legit, older consoles due to the nature of the code being altered. Whose person at Sony would authorize the expensive research and programming of updates that could possibly cause brickage in hundreds of thousands of consoles?
Not to mention patches with such fundamental programming and orders on the handling of private keys would be a feast for hackers. It could make matters even worse at the end.

i know retrieving them is a big task but the members were discussing any possible way sony could stop it.
i didn't say it would be easy but it is possible
and sony doesn't have to retieve all the keys just lock on whoever is using psn or buying new games
old games will still work

I've read this a few times and I have no idea what you're getting at.
Sony cannot revoke the old key without recalling every game sold. Period. No amount of firmware upgrades will change that.
I have no idea what you mean by "lock on whoever is using psn or buying new games." Do you mean instating a new key? Again, won't work because the old key will still work for anything, it has to remain valid or else everything before the new key would be invalid.
If the old key is still valid, then no new keys matter because all it takes then is to make a launcher with the old key that launches anything.
About the only way to fix it is revoke the old and even then it still won't work because then they can just downgrade the firmware and fool the PS3 into thinking it's using the current firmware. This can already be done.
Even by trying to monitor PSN users it's still pretty hopeless as long as they aren't actually cheating. Again, everything will be a completely legit signed app with no hardware or software changes. What do you think they're going to be looking for?
