Canadian encryption vendor Certicom yesterday filed a wide-ranging lawsuit against Sony, claiming that many of the products offered by the electronics giant infringe on two Certicom patents. This might sound like business as usual until you realize what's being targeted: AACS and (by extension) the PlayStation 3. Certicom has done extensive work in elliptic curve cryptography (ECC), and the patents in question build on this work. The patents have already been licensed by groups like the US National Security Agency, which paid $25 million back in 2003 for the right to use 26 Certicom patents, including the two in the...

San Francisco (IDGNS) - Under a licensing agreement in its final stages, consumers may get the right to make several legal copies of HD DVD and Blu-ray Disc movies they've purchased, a concession by the movie industry that may quell criticism that DRM (digital rights management) technologies are too restrictive. The agreement, if supported by movie studios and film companies, could allow a consumer to make a backup copy in case their original disc is damaged and another copy for their home media server, said Michael Ayers, a representative of an industry group that licenses the AACS (Advanced Access Content System)...

Building a business on mob rule is dangerous. Digg.com, a website that lets anyone post and rank news stories and blogs, found that out when its members staged a revolt over what they saw as an effort to censor them.

Digg took action because the entertainment industry had threatened to sue. The ban set the masses off. Scores of Digg's 1.2 million registered users deluged the site, breaking traffic records and making sure that every one of...

Excerpt - The folks at Digg.com have let the social news genie out of the bottle, and now they can't control it. Since the HD-DVD encryption code was discovered and published, readers at Digg have been repeatedly submitting stories with the 16 digit hex code in the titles and bodies. Just as quickly as these posts crawl up the Digg charts, admins seem to be deleting them. Just search Google for 09 F9 and you'll find the key. Will AACS send a Cease and Desist to InfoWorld because I posted the text "09 F9"? If so, we might as well...

LOS ANGELES (Reuters) - The companies behind an encryption system for high-definition DVDs are looking into a hacker's claim that he has cracked the code protecting the new discs from piracy, a spokesman for one of the companies said on Thursday. A hacker known as Muslix64 posted on the Internet details of how he unlocked the encryption, known as the Advanced Access Content System, which prevents high-definition discs from illegal copying by restricting which devices can play them. The AACS system was developed by companies including Walt Disney Co., Intel Corp., Microsoft Corp., Toshiba Corp. and Sony Corp. to protect...
