(Score 1) Comments: 532 by bushing on Wednesday December 29, @05:04PM (#34703922) Attached to: Playstation 3 Code Signing Cracked For Good Comments: 532 How did Sony fuck that one up? It was my(admittedly layman's) understanding that a public/private key crypto implementation, assuming it isn't deeply flawed, using key lengths suited to the computational capacities of PDP-8s, or otherwise totally fucked, was mathematically secure against anything other than a profound breakthrough in prime factorization algorithms, an unbelievable advance in computational power, or an insider leaking your private key. Close. These algorithms only work correctly if implemented correctly. There are various known pitfalls with each of these algorithms; for example, the original iPhone was unlocked using an RSA implementation error (Bleichenbacher attack against an RSA implementation that does not correctly validate padding and uses exponent 3). ECDSA happens to have a "pitfall" that leaks information inside the signatures it makes. This doesn't make it a bad algorithm -- it can achieve the same security of RSA using smaller keys and in less time -- but the "pitfall" here is particularly bad.

The exact signing key used by Sony may be derived from the public components of their ECDSA signatures. Not something close; not something equivalent. Games: Playstation 3 Code Signing Cracked For Good Posted by samzenpus on Wednesday December 29, @04:19PM from the forever-is-a-long-time dept. ReportedlyWorking writes Comments: 532 "It appears that Sony's PS3 has been fatally compromised. At the Chaos Communication Congress in Berlin, a team named 'fail0verflow' revealed that they had calculated the Private Keys, which would let them or anyone else generate signed software for the PS3. Additionally, they also claim to have a method of jailbreaking the PS3 without the use of a Dongle, which is the current method. If all these statements are true, this opens the door to custom firmware, and homebrew software. Assuming that Sony doesn't take radical action and invalidate their private keys, this could mean that Jailbreaking is viable on all PS3, regardless of their firmware! From the article: 'Approximately a half hour in, the team revealed their new PS3 secrets, the moment we all were waiting for. One of the major highlights here was, dongle-less jailbreaking by overflowing the bootup NOR flash, giving complete control over the system. The other major feat, was calculating the public private keys (due to botched security), giving users the ability to sign their own SELFs. Following this, the team declared Sony's security to be EPIC FAIL!'"

IOW they CANNOT change keys or fix this in a new firmware, because stuff we sign is every bit as good as existing official software.

As much as I like cute dog videos these guys need to post proper requirements and design specifications if they seriously want funding from me. Click through the links to the actual Kickstarter project description. We did some handwaving to keep it accessible for J.
