I think you're missing what I'm saying-- as long as the old key works for anything, it will always work for whatever homebrew they make.
It doesn't matter if they suddenly started using a new key, the old key will always work. The only way to get rid of that old key is to completely revoke for everything.

i know but the old key once changed will not
the old key can be locked on the newer stuff
the old stuff will still work
the new stuff's decrytion would e diffferent
the hackers could still hack it but it will take some time

You're either messing with me or you're just completely incapable of grasping the concept. Either way I'm saying it one more time and I'm done with you--
If the old key works for anything they always have a way in. No matter how many new keys they make, it will affect them in now way at all. The old key would still work and would continue to work unless they revoked it and made everything before that obselete.
The key has to do with convincing the PS3 that your app is legitimate, that's it. Once the PS3 thinks what you're running is legitimate, it's done. This isn't a per game thing they can change on a whim or even through a lot of work, it's just something they can't change. Changing means screwing everyone who bought a game before 2011 and they just can't do that.
So one more time hopefully as clear as possible:
- If the old key works for anything, it works for everything. There's no locking out the old key because every official app needs to work.
- You can't have multiple keys, it just doesn't work. That's like saying there's more than one solution for x - 4 = 8. There's only one solution for x there. You can change the equation to 4x = 8 but then the previous value of x is completely wrong in every way possible.
- Even if your idea did work, all they need to do is tell the PS3 you're playing Metal Gear Solid 4 when you're actually playing Super Awesome PS3 Game Launcher that just launched Killzone 3. The PS3 won't care because you have a valid digital signature for a game before the new key was introduced.

i wasn't messing,just my idea is kind of crazy and very tough to implement.
now one time i will explain myself:
the old games that will be playable on all ps3's
now someone buys a new game(updates firmware as required through game) or update firmware from internet,sony could add an additional way or decrytion while keeping the old decrytion method
the older decryption method which will work no matter what,but for new games a different decryption method is there that was put in by the firmware update.the new decrption method would need to be totally different from the current way of verifying whether an app is legit or not
although the hackers have control over the PS3's,they will need to decrypt the new way off veryify which will eventually be done but it will take some time so atleast there will be a gap where the exploit has been waded off.

Again, that's not the way you do it dude... if it was that easy Sony would already be doing it and the hackers mentioned it and trying a way around it.
This is a matter for an entire encryption team of mathematicians, programmers etc., not some random dudes over a forum to solve with a bit of brainstorming.
|
oh an ecryption team that don't understand the meaning of random,don't try to be "oh leave it to the pro's"
and to say if it was that easy sony would already be doing it,do you even know what you are saying or just being arrogant
just because they have an idea doesn't mean can already do it,it takes time to implement and alot of time.
