IBM Anti-Geohack Patent to Protect Secrets Against Attacks?!


Sponsored Links
241w ago - A few weeks back GeoHot Hacked PS3, and now a new [Register or Login to view links] has surfaced from Kanna Shimizu of IBM for a method to protect secrets against encrypted section attacks.

SKFU writes: It seems it is SONY's answer for GeoHot's progress.

Take a look here, to quote: "A method, system, and computer-usable medium are disclosed for controlling unauthorized access to encrypted application program code. Predetermined program code is encrypted with a first key.

The hash value of an application verification certificate associated with a second key is calculated by performing a one-way hash function. Binding operations are then performed with the first key and the calculated hash value to generate a third key, which is a binding key.

The binding key is encrypted with a fourth key to generate an encrypted binding key, which is then embedded in the application. The application is digitally signed with a fifth key to generate an encrypted and signed program code image.

To decrypt the encrypted program code, the application verification key certificate is verified and in turn is used to verify the authenticity of the encrypted and signed program code image. The encrypted binding key is then decrypted with a sixth key to extract the binding key.

The hash value of the application verification certificate associated with the second key is then calculated and used with the extracted binding key to extract the first key. The extracted first key is then used to decrypt the encrypted application code."

While I understood all the words in the description of this new patent, I have no idea how it works Sounds like lots of keys encrypting a bunch of other keys

Some BS in my opinion, this won't stop us from dumping the PS3's ram.

Note how he completely changed the subject from PS3 to new encryption scheme.

Go figure, big talk.

I really think the likes of Sony, Nintendo et all miss the point with the homebrew development a lot of people try to do

For the few people that are sitting around trying to secure these devices (and rightly so given that they're trying to protect their intellectual property) there will be hundreds, possibly thousands more trying to break it for whatever reason; curiosity, enhance functionality, piracy (if that's your thing) respect/kudos in the dev community or just to see if they can do it and test their technical skill.

Personally, I have no technical skill so I'm of the ilk that thinks if a machine is capable of SO much more, why limit it? (Put a DVD drive in a Wii and then disable the DVD playback functionality Nintendo? I mean really? :confused)

Naturally, the response from the manufacturers/developers and the like will be so we can make more money out of you. I just think they need to encourage creative development. As much as whoever will try to protect things, there will always be people to trying to break the protection.

I think one of the best things Sony did with the original PS3 was giving it the ability to run a Linux distro. If you've got that running, think of the functionality that gives you. I think rather than lock things down to, they should really try and encourage stuff like iTunes and the iPhone/Touch application model where here you go. You make apps and games that people want and then we charge for it together. You make money. We make money.

By patenting and further trying to lock it down, you're just going to be challenging the creative devs/hackers to break you down further.

That's my two cents anyway
