Software to unlock Blu-ray, HD DVD

The cat-and-mouse game between the film industry and those who want to have the freedom to access the content on the optical disc they have spent on buying has just stepped into a new round.

The Slysoft Software Company yesterday (May 17) has released an AnyDVD HD application update that has been added to bypass the latest AACS copy protection mechanism allowing users to freely copy the content above. Any Blu-ray or HD DVD disc.

AACS technology encodes content on high-resolution optical discs to prevent duplication. The encryption mechanism uses two standard keys to decode the content. One is the device key (device key) that is usually applied on the software and the disk headers. Two is the volume key, which is stored directly in digital content on the disk.

But finding and integrating these keys into copying software is relatively difficult. That's why hackers mainly focus on finding device keys and then automatically finding content keys.

Last February locked the device in the detected WinDVD software and posted it online to all users to copy the content. A month later PowerDVD turns into a similar situation.

Soon after, AACS had to upgrade the system with a series of completely new encryption systems and require manufacturers to upgrade the system and software. Failure to upgrade means that the software or the player cannot see the disc anymore.

But hackers just need to change the mechanism of winning a device key a little bit and can bypass the advanced security system of AACS and freely copy the content on the disk.

For example, the Matrix Trilogy movie released on HD DVD using the latest AACS protection mechanism only survived 24 hours. AnyDVD HD 6.1.5.1 software is available to copy all content on this disc.

AACS has previously expressed dissatisfaction with the disclosure of the product key, but so far the agency has not taken any legal action against software publishers that allowed copying of content. protect.
