This article needs to be updated. Please update this article to reflect recent events or newly available information. August 2. For other AACS uses, see AACS. The Advanced Access Content System AACS is a standard for content distribution and digital rights management, intended to restrict access to and copying of the post DVD generation of optical discs. The specification was publicly released in April 2. HD DVD and Blu ray Disc BD. It is developed by AACS Licensing Administrator, LLC AACS LA, a consortium that includes Disney, Intel, Microsoft, Panasonic, Warner Bros., IBM, Toshiba and Sony. AACS has been operating under an interim agreement since the final specification including provisions for Managed Copy has not yet been finalized. Since appearing in devices in 2. X9sClw-wXqM/0.jpg' alt='How To Hack Viaccess' title='How To Hack Viaccess' />AACS decryption keys have been extracted from software players and published on the Internet, allowing decryption by unlicensed software. System overvieweditEncryptioneditAACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard AES. Title keys are decrypted using a combination of a media key encoded in a Media Key Block and the Volume ID of the media e. The principal difference between AACS and CSS, the DRM system used on DVDs and CDs, lies in how the device decryption keys and codes are organized. Under CSS, all players of a given model group are provisioned with the same shared activated decryption key. Content is encrypted under the title specific key, which is itself encrypted under each models key. Thus each disc contains a collection of several hundred encrypted keys, one for each licensed player model. In principle, this approach allows licensors to revoke a given player model prevent it from playing back future content by omitting to encrypt future title keys with the player models key. In practice, however, revoking all players of a particular model is costly, as it causes many users to lose playback capability. The Advanced Access Content System AACS is a standard for content distribution and digital rights management, intended to restrict access to and copying of the post.

Furthermore, the inclusion of a shared key across many players makes key compromise significantly more likely, as was demonstrated by a number of compromises in the mid 1. The approach of AACS provisions each individual player with a unique set of decryption keys which are used in a broadcast encryption scheme. This approach allows licensors to revoke individual players, or more specifically, the decryption keys associated with the player. Thus, if a given players keys are compromised and published, the AACS LA can simply revoke those keys in future content, making the keysplayer useless for decrypting new titles. AACS also incorporates traitor tracing techniques. The standard allows for multiple versions of short sections of a movie to be encrypted with different keys, while a given player will only be able to decrypt one version of each section. The manufacturer embeds varying digital watermarks in these sections, and upon subsequent analysis of the pirated release the compromised keys can be identified and revoked this feature is called Sequence keys in the AACS specifications. Volume IDseditVolume IDs are unique identifiers or serial numbers that are stored on pre recorded discs with special hardware. They cannot be duplicated on consumers recordable media. The point of this is to prevent simple bit by bit copies, since the Volume ID is required though not sufficient for decoding content. On Blu ray discs, the Volume ID is stored in the BD ROM Mark. To read the Volume ID, a cryptographic certificate the Private Host Key signed by the AACS LA is required. However, this has been circumvented by modifying the firmware of some HD DVD and Blu ray drives. Decryption processeditTo view the movie, the player must first decrypt the content on the disc. Satyam Telugu Movie Songs. The decryption process is somewhat convoluted. The disc contains 4 itemsthe Media Key Block MKB, the Volume ID, the Encrypted Title Keys, and the Encrypted Content. The MKB is encrypted in a subset difference tree approach. Essentially, a set of keys are arranged in a tree such that any given key can be used to find every other key except its parent keys. This way, to revoke a given device key, the MKB needs only be encrypted with that device keys parent key. Once the MKB is decrypted, it provides the Media Key, or the km. The km is combined with the Volume ID which the program can only get by presenting a cryptographic certificate to the drive, as described above in a one way encryption scheme AES G to produce the Volume Unique Key Kvu. The Kvu is used to decrypt the encrypted title keys, and that is used to decrypt the encrypted content. Analog OutputseditParts of this article those related to This needs to be updated so it doesnt deal mostly with the obsolete HD DVD format need to be updated. Please update this article to reflect recent events or newly available information. November 2. AACS compliant players must follow guidelines pertaining to outputs over analog connections. This is set by a flag called the Image Constraint Token ICT, which restricts the resolution for analog outputs to 9. Full 1. 92. 01. 08. HDMI or DVI outputs that support HDCP. The decision to set the flag to restrict output down convert is left to the content provider. Warner Pictures is a proponent of ICT, and it is expected that Paramount and Universal will implement down conversion as well. Airplane Simulator Games. AACS guidelines require that any title which implements the ICT must clearly state so on the packaging. The German magazine Der Spiegel has reported about an unofficial agreement between film studios and electronics manufacturers to not use ICT until 2. However, some titles have already been released that apply ICT. Audio watermarkingeditOn 5 June 2. AACS were finalized, which were updated to make Cinavia detection on commercial Blu ray disc players a requirement. Managed CopyeditManaged Copy refers to a system by which consumers can make legal copies of films and other digital content protected by AACS. This requires the device to obtain authorization by contacting a remote server on the Internet. The copies will still be protected by DRM, so infinite copying is not possible unless it is explicitly allowed by the content owner. It is mandatory for content providers to give the consumer this flexibility in both the HD DVD and the Blu ray standards commonly called Mandatory Managed Copy. The Blu ray standards adopted Mandatory Managed Copy later than HD DVD, after HP requested it. Possible scenarios for Managed Copy include but are not limited to Create an exact duplicate onto a recordable disc for backup. Create a full resolution copy for storage on a media server. Create a scaled down version for watching on a portable device. This feature was not included in the interim standard, so the first devices on the market did not have this capability. It was expected to be a part of the final AACS specification. In June 2. 00. 9, the final AACS agreements were ratified and posted online, and include information on the Managed Copy aspects of AACS. HistoryeditOn 2. February 2. Dalit Naor, Moni Naor and Jeff Lotspiech published a paper entitled Revocation and Tracing Schemes for Stateless Receivers, where they described a broadcast encryption scheme using a construct called Naor Naor Lotspiech subset difference trees.
