Forums - Sony - So what will Sony do to fix the exploit?

double post....

Why can't they create a duplicate key, assign it to a(n) actual random number, get rid of the old keys, and replace it with those keys, since they have all the old values anyway, just a different code.

This just came off the top of my head so... why not?

You know I have been thinking about how this will affect software sales. I honestly think this will not affect software sales that much. PSP ans PS3 are different because the PSP got cfw very early in its lifecycle. PS3 just now got it may not be that significant. Also sony is a multi billion dollar corporation. They will find a way to fix this, homefully

 SONY have only one way to fix this it is called PS4!



Japanese Pop Culture Otaku

Considering the PSP, Wii, 360, ps2, xbox, gamecube and DS all got hacked within first or two year i think its still a sony win ^^



Yeah i know my spelling sucks but im dysgraphic so live with it :3

Conegamer - I say that the PS3 will beat the DS next week in Japan  (for hardware sales) Forfeit is control over others avatar for 1 week.

Its depressing to see how PS3 has became the most open of the three. Its good and exciting for the homebrew scene, although most forums I go to are just excited to play downloaded games.

It seems the lot of you can't gasp the concept of the "key" and twesterm is pulling his hair trying to explain, lol.



ignore-posted on wrong thread

as twestern pointed it out

the ps3 is the most environmental friendly, since is HD with very low power consumption and doesn't require AAA batteries which are bad for environment.

And if you going to talk about low power consumption in SD, try comparing the wii with a ps2 slim with wireless controllers .


Are you even in the right thread?

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.



Nothing, it was always going to happen one day.
