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'm not sure of it. Even in the case you are right, there would still be the issue of a firmware contaning all the white/blackmailed lists that could be easily edited, rendering useless the entire process.
Besides, if there was no fix for both the PSP / Wii homebrew scenes, I doubt Sony would go all the way to stop it - there is sort of a myth around Sony and the PS3 security IMO that they would go any lengths to make the PS3 a fortress of sorts. Yes, they had a lot of fw updates who fixed security issues and whatever, but most of them were second thoughts to, say, giving the XMB and PSN to what Microsoft and NIntendo already offered.
Anyways, what should worry Sony the most (and the others too, for that matter) is the AACS keys leaking. Every PS3 released so far is a potential and unfixable blu ray ripper. Simply taking BD support like they did with linux would be suicidal, since it would obviously be deemed illegal and lawsuits would follow.
The best things Sony could do IMO are:
1 - completely revamp the BIOS and usie different encryption on future consoles. Since those will mostly be sold at 3rd world countries, it would be very effective against piracy. However, due to full access to previous PS3 master codes and so it wouldn't be long until someone came with a modchip or neo Jailbreak. Anyways, it wouldn't be different from most consoles on this aspect.
2 - give the PS3 everything the homebrew scene are looking to offer - different browsers, Linux, 3rd party support etc. It would keep the big hackers uninterested on it and diminish the appeal of methods which could be used to games / blu ray piracy.
3 - release PSP-2 and PS4 earlier than planned if the worst come to be true. Honestly, we stand very close to it so far... Sony's bad luck has been of karmic proportions the last few days.
