DVD Security Group Says It Has Fixed AACS Flaws

SkillZ wrote to mention an article at the IBT site discussing a fix to the security breech of the HD DVD and Blu-ray media formats. "Makers of software for playing the discs on computers will offer patches containing new keys and closing the hole that allowed observant hackers to discover ways to strip high-def DVDs of their protection. On Monday, the group that developed the Advanced Access Content System said it had worked with device makers to deactivate those keys and refresh them with a new set."

    I bought an expensive (~$800) region free player from a well know Japanese company. The picture and sound quality is far supperior, and comes with a nice built in scaler for connecting to my HDtv. Region free does not have to equal low quality

    Then bandwith grew -- 28.8 gave way to 56.6 gave way to 128kbps and then on to broadband -- initially 700kbps or thereabouts, today typically 2-4Mbps in the USA, 5 - 25 mbps in Norway. Just FYI. My broadband provider here in the ~350,000 person metro area in a mostly rural section of the midwest USA doesn't offer anything lower than 3Mbps and will go as high as 10Mbps.

    I know that faster alternatives exist in some parts of USA. I still believe 2-4mbps is "typical" though, and that's what I said. Actually I'm certain there's a lot more people on speeds UNDER 2mbps than there are on speeds ABOVE 4mbps.

    There's 100mbps symetrical available in parts of Norway (from BKK), but it's not typical, first its only available in a small fraction of the country, and secondly, even where it's available a small portion of the population care to pay for it. My ISP for example has 6, 25 and 50mbps available, and say outrigth that the only reason they offer nothing higher is "no demand", even at the current speeds 75% of the customers go for the slowest alternative. 6mbps is sufficient for most internet-use afterall.

    The physical infrastructure is single-mode fibre-to-the-basement of every house, and GB ethernet internally in the houses. The physical fibre can handle multiple GB (if not TB), so that's certianly not the issue. (they do use some of it for offering around 100 channels TV over the same fibre though)

    The hackers only figured out how to get the old key. Which means they have a method for defeating arbitrary keys.

    The hackers don't have the new key. The new key can be discovered by the same method used to extract the old one. Even encrypting, splitting, or otherwise obfuscating the new key only adds a layer; the code is also exposed in RAM and can be reverse-engineered so ultimately the same attack should work.

    What are you, stupid? Yeah, that's me. Thanks for pointing it out.
