Καλή η ανάλυση όπως επίσης και τα σχόλια.

Πάρα πολύ καλή - για την ακρίβεια υποδειγματικά καλή. Έτσι πρέπει να γράφονται άρθρα για περίπλοκα τεχνικά θέματα, ώστε να είναι προσιτά στον πολύ κόσμο.

Ισχυρίζεται ότι έσπασε και το Blu-Ray, αν και σε ταινία που δεν συμπεριλαμβάνει την επιπρόσθετη κρυπτογραφική στιβάδα BD+.

Ο τύπος φαίνεται να είναι πολύ καλός.Μέσα σε λίγες μέρες "ασχολήθηκε" και με το Υψηλής Πυκνότητας ή Ευκρίνειας Δίσκο και με τη Γαλάζια Ακτίνα. Ελπίζω να μην τον πάρουν στο κυνήγι

"HD players hand over DVD keys

JANUARY 26, 2007
A consortium backing the encryption system for high-definition DVDs has confirmed hackers have stolen "title keys" and used them to decrypt high-definition discs.

Both the title keys and a number of decrypted films have been posted on peer-to-peer websites, a spokesman for the Advanced Access Content System (AACS) Licensing Authority said.

The large size of the files and the high cost of writable hi-definition discs made large-scale copying of high-definition DVDs impractical. But the attacks on the new format echoed the early days of illegal trafficking in music files, AACS spokesman Michael Ayers said.

"We want to make sure we address this now. It has a potentially limited impact now but some sobering possibilities," Mr Ayers said.

The hackers did not attack the AACS system itself, but stole the keys as they were exchanged between the DVD and the player to strip the encryption from the film.

A large-scale failure of AACS could be a threat to the $US24 billion DVD industry, which has started to cool and was counting on next-generation DVD sales to reinvigorate it.

The hackers obtained the keys from "one or more" player applications but AACS would not identify them or say whether their AACS licensing would be revoked.

"We certainly have not ruled out any particular response and we will take whatever action is appropriate," Mr Ayers said.

The security breach affects both of the high-definition DVD formats - Sony Corp's Blu-Ray and Toshiba's HD DVD, Mr Ayers said.

The confirmation of the attack comes about a month after a hacker called Muslix64 described in an online posting how he defeated the encryption system by using DVD player software.

AACS LA founders include IBM, Microsoft, Panasonic, Sony, Toshiba, Walt Disney, and Warner Bros Studios."

Επίσης η άποψη των Αμερικάνων καταναλωτών για το downloading:

"Pirate downloads no big deal
Etan Vlessing in Toronto
JANUARY 26, 2007
MOST Americans regard the illegal downloading and distribution of Hollywood movies as something on par with minor parking offences.

Only 40 per cent of Americans polled by the Toronto-based Solutions Research Group agreed that downloading copyrighted movies on the internet was a "very serious offence".

That compares with the 78 per cent who said shoplifting a DVD from the local video store was a very serious offence.

"There is a Robin Hood effect. Most people perceive celebrities and studios to be rich already and as a result don't think of movie downloading as a big deal," said Kaan Yigit, study director at Solutions Research Group.

The survey found that 59 per cent of Americans polled considered "parking in a fire lane" a more serious offence than movie downloading.
Mr Yigit said that existing download-to-own movie services and new market entrants would need to be more flexible in first-run and catalogue content offerings and pricing if they wanted to convince consumers to pay copyright holders for product.

"Otherwise file-sharing will continue to thrive," he said.

The Digital Life America survey polled about 2,600 Americans between June and late September.

-Εκατομμύρια δολάρια για τα νέα super -duper κλειδώματα!

- Ταλαιπωρία χρήμα για τους καταναλωτές και κυρίως αδιαφορία απέναντί τους καθώς πολλοί είναι αυτοί που πρέπει να αγοράσουν νέες τηλεοράσεις για να μπορούν να δουν τα νέα φορμά.

-Τεράστιο κόστος που ενσωματώνεται στις νέες συσκευές και στους τίτλους και φυσικά το πληρώνουμε εμείς οι καταναλωτές.

-Ατέλειωτες συζητήσεις και μήνες καθυστερήσεων για τα νέα φορμά μέχρι να είναι σίγουρα τα studio ότι θα υπάρχει η καλύτερη προστασία.

Και το αποτέλεσμα; Λίγους μήνες άντεξαν... και μάλιστα από ότι διάβασα ήταν και πιο εύκολο να ξεκλειδώσει από ότι το dvd...

Βέβαια σιγά μην βάλουν μυαλό...

Νέα εκατομμύρια δολάρια θα ξοδευτούν... η ανάπτυξη των νέων φορμά ίσως καθυστερήσει μέχρι να έχουμε νέα super κλειδώματα...

Μία ιστορία για γέλια ή για κλάματα...

The New HD-DVD/Blu-Ray Hack: What It Might Mean For Us

09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

That's the so-called "Processing Key" that unlocks the heart of every HD-DVD disk to date. Happy Valentine's day, AACS.

AACS, a DRM scheme used to encrypt data on HD-DVD and Blu-Ray disks, would appear to be cracked wide open by that short string of hexadecimal codes, as previously, only disk-specific Volume Keys were compromised. The new hack is the work of Arnezami, a hacker posting at the doom9 forums, fast becoming the front line in the war on DRM.

"The AACS is investigating the claims right regarding of the hack," said AACS spokesporson Jacqueline Price. "It is going to take a appropriate action if it can be verified."

Price said she could not disclose what their investigation might entail, or what "appropriate action" might be.

“We’ve just learned of this claim today and are checking into it,” said Andy Parsons, chair of the Blu-ray Disc Association and senior V.P. of product development at Pioneer Electronics, in an email.

The new crack follows that from earlier this year, when a hacker by the name of muslix64 broke the AACS system as it applied to each movie. While the earlier hack led to 100 HD-DVD titles and a small number of Blu-Ray movies being decrypted one-by-one, the so-called "processing keys" covers everything so far made.:

"Most of the time I spend studying the AACS papers," Arnezami said in his forum post revealing the successful assault on the next-gen DRM system. "... what I wanted to do is "record" all changes in this part of memory during startup of the movie. Hopefully I would catch something insteresting. ... I now had the feeling I had something. And I did. ... Nothing was hacked, cracked or even reverse engineered btw: I only had to watch the "show" in my own memory. No debugger was used, no binaries changed."

It's not yet clear what it means for the consumer's ability to copy movies, or, for that matter, that of mass-market piracy operations. The short form is that the user still needs a disk's volume ID to deploy the processing key and break the AACS encryption — but getting the ID is surprisingly easy.

Arnezami found that they are not even random, but often obvious to the point of foolishness: one movie's Volume ID turns out to be it's own name and the date it was released. There isn't yet an automatic system, however, that will copy any disk, in the manner of DeCSS-based DVD copying systems.

Even so, the new method completely compromises HD-DVD in principle, as it relies on AACS alone to encrypt data, even if there are other parts of the puzzle that are yet to fit together. Blu-Ray has two more levels of protection: ROM-MARK (a per factory watermark, which might revoke mass production rights from a factory but not, it seems individuals) and BD+, another encyption system, which hasn't actually been used yet on sold disks (but which soon will be), meaning that its own status seems less obviously compromised.

How might the companies respond? The processing key can now be changed for future disks. However, the flaws inherent in the system make it appear easy to discover the replacement: the method of attack itself will be hard to offset without causing knock-on effects. For example, revoking player keys (in advance of obfuscating the keys in memory in future revisions of the system) would render current players unable to view future movies. Revoking the volume and processing keys that have been hacked would mean that all movies to date would not run on new players.

Publishers could randomly generate Volume IDs in future releases (as they are still needed for the current hack to work), which would make them harder to brute-force. That said, it's claimed that the "specific structure" of the Volume ID in memory makes it feasible to brute-force randomized ones anyway.

Following are links to the current discussion at the doom9 forums, in which Arnezami and other provide regular updates on their progress. We don't offer any warantee that the software implementations so far produced won't blow up your computer or get you thrown in jail and whipped with wet towels by MPAA lawyers:
