Ars Technica looks at a crack to AACS that may be undefeatable. AACS, for those new to these things, is the DRM behind the "security" in HD-DVD and Blu-Ray.|
Although AACS has proven much more difficult to fully crack than the copy protection on regular DVDs, it is unlikely to remain only partially cracked for very long. The real problem with trying to create an "uncrackable" copy protection is that the media must come with the keys used to decrypt it somewhere on the device and the media itself. Hiding these keys in different places?security by obscurity?merely delays the inevitable."If it can be seen, it can be copied."
