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.
