Hackers crack HD-DVD encryption

It's been confirmed that a hacker has managed to crack the AACS protection system used for HD-DVD movie discs, enabling others to make illegal copies.

According to the BBC Technology website, the Advanced Access Content System Licensing Authority has said that the hack can only be used on a limited number of titles, stating, "It does not represent an attack on the AACS system itself."

The licensing authority said the hacker had managed to access encryption keys from "one or more" software programs used to play HD-DVDs, but declined to name them.

Spokesperson Michael Ayers said HD-DVD files are so large and the discs so expensive that it would be impractical to attempt large scale copying.

He did not reveal whether AACS licenses will be revoked, stating, "We certainly have not ruled out any particular response and we will take whatever action is appropriate."
