    well if this is real then no wonder they started charging for other firmware support, i thought they would have charged people money to use it on an earlier firmware...but this makes more sense.

    keep in mind this is just a rumor and could very well be false.

    im pretty sure this is just more bs from the official jb team trying to sell more jailbreaks
    they have already said they are releasing bm v1.1 over a month ago and every time the due date comes they delay it another 2 weeks
    the new date is oct.19 but they will probably "delay" it again...

    i've heard this...

    very hard to believe.

    this is the most precious thing sony have... when you see how angry they are already they sue everybody out there,

    the masterkey, they could kill for that.

    i admit i'm new to the ps3 scene. what does the master key do and couldn't they just change it in a newer firmware?

    okay i dont know if i'm right about this, but if this turns out to be true then they will basically beable to do anything they want with the system. from what i have been reading the masterkey is hardware related not software so a update would be useless, but like i said i dont know this is just what i have been reading.

    there are at least 2 very important keys, one to encrypt official software and one to decrypt it. every ps3 has the key to decrypt software, but i think it's not known(yet).

    with the 1st key hackers could easily release a custom firmware that could be installed on all ps3s and not need a kailbreak device to boot. with the 2nd key hackers could decrypt firmwares and then disassemble them in order to get to know how things work and find exploits.

    anyways, blablabla and tt has the private key for the wii and is not releasing bootmii boot2 for newer wiis because they are all a..holes...

    part of deltaburns quote

    "when i meant someone, it has the possibilities of someone who have worked for sony or had left the company for several obvious reasons"
    stop there i had a feeling someone would come to our side with so many unethical things sony has done since the otheros exploit no wonder somebody got fed up

    it depends on the security implementation. for example recently the hdmi master key used to protect the digital stream between devices was leaked. because of the underlying security architecture, this totally broke the entire implementation. to re-secure, they would need to revoke all existing keys and make everyone update their devices. this isn't practical so they won't be doing that.

    in this case, what will happen is that if the master key is leaked, sony will simply generate a new one and require that compiled for all new games. just as how 3.42 games like moh require the new sdk that is compiled with this master key. thus releasing the key at this point would mean moh would work. but then once they release firmware 3.6 or whatever, they'll simply be required to compile with a new master key and thus invalidate the leak.

    is it possible that the master key is hard coded? i mean, if it's used to decrypt firmware packages then it would create a split path. to go to a higher version you'd first have to go to a version that installs a new key. but that package would use the old key so getting the new key from that package would there for make any attempts at changing the master key irrelevant?

    It's delayed. Check the homepage:
    I really hope they haven't got the master key, because then Sony is f*cked and so are the game developers.

    In situations like this the master key is almost never located on the system. I'll use the HDCP as an example. There a master key is used to generate keys that are used in the public. If a key in the public is compromised, it is revoked. This is so that you can spend lots of time to try and brute force a key, but it just gets revoked so your work has a very narrow window of operation, after which you have to start over.

    Having the master key means you can freely generate your own public keys that absolutely valid. This makes revocation complicated. Since now you need a whitelist, not a blacklist. You don't want whitelists on machines since then cracking efforts are more valuable essentially opening up the entire valid keyspace to hackers.

    But lets even assume a 'master key' was on the PS3. This still is irrelevant. The master key would only be valid for everything up to and including that point. Sony has the luxury of automatically disabling backwards compatibility for new games by enabling new firmware with a new key. Something that is not practical with the HDCP scenario. It's trivial for Sony to get a new key, push firmware, and make devs re-compile with the new key. Old games will still work, but again you're stuck with new games not working, and no key to decode it with.

    There can't be constant 'leaks' of the master key. It might happen once, but after this time, you can be sure the master key will be chopped into 10 pieces and scattered to the far reaches of Pluto. Access to them will be guarded and audited. So leaks can be traced to specific people who will probably all get fired.

    If they have the firmware keys then they shouldn't worry about updating for new Sony firmwares, but instead trying to reverse engineer a CFW.

    If I understand correctly what doyama was saying, a CFW would be possible, but only up to 3.50 because with the next update a new key would be introduced and so you can't have a CFW for higher firmwares, unless the new key would be leaked as well, which the chance of is very minor. Correct me if I'm wrong.

    And you'll also need the luck to have the key right now, I still can't believe the PSJailbreak team has any sort of key.

    The master key doesn't have much to do with CFW. CFW could include the master key to decode specific games that needed it. But it could also contain features such as ISO loading, pkg install, NTFS support, etc. The master key allows for the decryption of the EBOOT file that is currently encrypted in some games like the current MOH. In this specific situation, they could generate a new key, issue new firmware, make devs use this new SDK, and we'd be in the same boat unless the key was leaked yet again.

    So to summarize you could have CFW in theory for any firmware version. Whether you can decrypt the EBOOT.BIN file is a separate problem.

    Backup Manager v1.1 is released. Samples of the update for new firmwares are available for distributors.

    everyone who tested 1.1 (including me) say its exactly the same

    all they did was change the name in the menu
