From Nate Anderson’s “Hacking Digital Rights Management” (Ars Technica: 18 July 2006):
AACS relies on the well-established AES (with 128-bit keys) to safeguard the disc data. Just like DVD players, HD DVD and Blu-ray drives will come with a set of Device Keys handed out to the manufacturers by AACS LA. Unlike the CSS encryption used [...]

From Nate Anderson’s “Hacking Digital Rights Management” (Ars Technica: 18 July 2006):
DVD players are factory-built with a set of keys. When a DVD is inserted, the player runs through every key it knows until one unlocks the disc. Once this disc key is known, the player uses it to retrieve a title key from the [...]

From Nate Anderson’s “Hacking Digital Rights Management” (Ars Technica: 18 July 2006):
The attacks on FairPlay have been enlightening because of what they illustrate about the current state of DRM. They show, for instance, that modern DRM schemes are difficult to bypass, ignore, or strip out with a few lines of code. In contrast to older [...]

From Nate Anderson’s “Hacking Digital Rights Management” (Ars Technica: 18 July 2006):
A third approach [to subverting Apple's DRM] came from PyMusique, software originally written so that Linux users could access the iTunes Music Store. The software took advantage of the fact that iTMS transmits DRM-free songs to its customers and relies on iTunes to add [...]

From Mark Sableman’s “Copyright reformers pose tough questions” (St. Louis Journalism Review: June 2005):
It goes by the name “digital rights management” - the effort, already very successful, to give content owners the right to lock down their works technologically. It is what Washington University law professor Charles McManis has characterized as attaching absolute “trade secret” [...]

From Bruce Schneier’s “Microsoft’s BitLocker” (Crypto-Gram Newsletter: 15 May 2006):
BitLocker is not a DRM system. However, it is straightforward to turn it into a DRM system. Simply give programs the ability to require that files be stored only on BitLocker-enabled drives, and then only be transferable to other BitLocker-enabled drives. How easy this would be [...]

From Scott Kleper’s “An Introduction to Copyfighting“:
I think a lot of people incorrectly assume that Copyfighters are people who believe that copyright should be abolished and that everything should be free. Copyfighters aren’t saying that all media should be freely distributed. We are saying that as consumers of media (film, television, software, literature, etc.) we [...]

From Technology Review’s “Taming the Web“:
Nonetheless, the claim that the Internet is ungovernable by its nature is more of a hope than a fact. It rests on three widely accepted beliefs, each of which has become dogma to webheads. First, the Net is said to be too international to oversee: there will always be some [...]

From “The Big DRM Mistake?“:
Fundamentally, DRM is a about persistent access control - it is a term for a set of technologies that allow for data to be protected beyond the file system of the original machine. Thus, for example, the read/write/execute access control on most *nix file systems will not only be applicable to [...]

From “Cartridge Expiration Date Workarounds“:
In light of the lawsuit against Hewlett-Packard over the expiration date of their cartridges, two ways to fix the problem:
1) Remove and reinsert the battery of the printer’s memory chip
2) Preemptive: Change the parameters of the printer driver

NBC’s “The Office” delivered a 5.1-its highest ratings ever-last Thursday among adults 18 to 49, a bump the network credits in large part to the show’s popularity as an iPod download. …
Such a connection between podcast success and broadcast ratings success is particularly significant because the NBC data is among [...]

From Edward Felten’s "DRM and the Regulatory Ratchet":
Regular readers know that one of my running themes is the harm caused when policy makers don’t engage with technical realities. One of the most striking examples of this has to do with DRM (or copy-restriction) technologies. Independent technical experts agree almost universally that DRM is utterly unable [...]
