September 7, 2007 - AACS LA Announces Security Updates
Advanced Access Content System Licensing Administrator, LLC (â€œAACS LAâ€) announces that it has taken action to expire AACS encryption keys being used in an illegitimate product made by an unlicensed party to make unauthorized copies of HD DVD and Blu-ray movies. In accomplishing this expiration, AACS LA worked closely with the licensee which manufactured the player from which the AACS keys were extracted.
Consumers can easily continue to enjoy content that is protected by the AACS technology by downloading the latest version of their HD DVD and Blu-ray software players, thereby refreshing the encryption keys associated with those players. Consumers are advised to check with the manufacturer of their AACS-enabled Blu-ray or HD DVD PC-based player to make sure you have installed the latest version. The following manufacturer has provided a link to provide relevant information and facilitate consumer updating of their players:
September 7, 2007 â€“ AACS LA Announces Commencement of â€œProactive Renewalâ€
AACS LA announces that it has started periodic â€œproactive renewalsâ€, which, primarily for software player applications, provide for periodic renewal and refreshing of AACS encryption keys by licensed manufacturers and eventual expiration of old keys by AACS LA. This helps maintain the AACS technology as a vital means of distributing valuable high definition content to consumers. Consumers should expect that updates/patches will be periodically offered by their software manufacturer in order to ensure that the players continue to function as intended. The upgrading of software is a common practice in the software industry. Pursuant to the AACS technology licenses, manufacturers of software players are required to perform such updates in a consumer-friendly fashion.

AACS LA began several weeks ago sending letters to parties trafficking in tools used to circumvent AACS technology on Blu-ray and HD DVD movie discs. The letters requested the removal solely of illegal circumvention tools, including encryption keys, from a number of web sites. AACS LA recognizes the value of active public discussion and commentary related to these issues, and has not requested the removal or deletion of any such discussion or commentary. AACS LA is encouraged by the cooperation it has received thus far from the numerous web sites that have chosen to address their legal obligations in a responsible manner.

Regarding the reported attacks on 2/13/2007, AACS has confirmed that an additional key (called a â€œprocessing keyâ€) has been published on public websites without authorization. This is a variation of the previously reported attack (a compromise of a specific implementation) on one or more players sold by AACS licensees. Although a different key was extracted, this represents no adverse impact on the ability of the AACS ecosystem to address the attack. All technical and legal measures applicable to the previously reported attack will be applicable against this attack as well.

AACS LA has confirmed that AACS Title Keys have appeared on public web sites without authorization. Such unauthorized disclosures indicate an attack on one or more players sold by AACS licensees. This development is limited to the compromise of specific implementations, and does not represent an attack on the AACS system itself, nor is it exclusive to any particular format. Instead it illustrates the need for all AACS licensees to follow the Compliance and Robustness Rules set forth in the AACS license agreements to help ensure that product implementations are not compromised. AACS LA employs both technical and legal measures to deal with attacks such as this one, and AACS LA is using all appropriate remedies at its disposal to address the attack
I hope this will help some of you to reliaze what went on with the Blu-Ray stuff
