PS3 Chain of Trust - old vs new - implications/possibilities
PS3 Chain of Trust - old vs new - implications/possibilities –
Alright i'm just reading up so if i'm asking stupid questions just kick me in my n00b face. I was reading about the boot order Boot Order - PS3 Development Wiki
So if i'm reading this correctly; since the loaders lv1ldr, lv2ldr, appldr, isoldr are now entirely encaptulated by the lv0, and since the metldr was used to load the loaders. Is the metldr useless now as in, is it still there loading the loaders and only the chain of trust is changed? In the usage column in the article i don't see anything decrypting or loading the metldr, so that made me wonder.
Also i read that everyone is trying to exploit the lvl0, but isn't the bootldr easier since it's non patchable and it is run in an SPE (0), and since we've already managed to exploit ldr's that are run in an SPE (2) or is it totally unrelated or does the per console encryption raise a problem?
I'm probably rambling like an ass but i just want to understand more about how this friggin thing works.
Some one can correct me if I am wrong. But the current way the PS3 is setup with 3.60+ is that lv0.2 is a meta data that basically covers everything else. So everything we have done isn't useless they just simply added a layer of security by redirecting everything through this new metadata. If we crack the keys from this metadata we still have full access. So it's the same game, just harder. But the key crypto **** up has been fixed with this new metadata. So I believe we have to use a glitch, or ram dump or something to get the keys instead of cracking it with cryptography.
Math just said either yesterday or the day before yesterday that lv0.2 isn't what the devs are going at for the hardware we're using right no. That's for any new hardware we haven't seen yet. I'm gonna try to find that post of his.
