Encrypted Title Key
Encrypted Title Key is an encrypted key that belongs to anticopy Advanced Access Content System (AACS). This key is included in the Media Key Block system and is an important part of the content protection process of Blu-ray and HD-DVD contents. What is it used for? The main objective of the Encrypted Title Key is to reinforce the discs’ content security during the decryption process of content stored in the media. The content stored in medias like Blu-ray or HD-DVDs is composed and divided in information units called Titles. The owner of the protected contents, divide this information in the form of one or more Titles. It also provides a license to the player, a series of rules called Usage Rules which will be used later on to decrypt the disc information. To protect the content, the information units are encrypted using encryption keys called Title Keys. To achieve more security and so that the key obtention process cannot be obtained by player without license, the Title Keys ...

Advanced Access Content System
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 2005 and the standard has been adopted as the access restriction scheme for 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 2006, several AACS decryption keys have been extracted from software players and published on the Internet, allowing decryption by unlicensed software.

Media Key Block
The Media Key Block (MKB) is one of the keys included inside the copying protection system (DRM) AACS. This system is used to prevent Blu-ray and HD DVD formats from being copied. The system was developed by companies from the film industry and the electronics industry including IBM, Intel, Microsoft, Matsushita (Panasonic), Sony, Toshiba, The Walt Disney Company and Warner Bros. The MKB key is found in the physical support (the disc) together with the content of the disc encrypted. The ''MKB'' has the function of validating the reproduction devices on which the disc is being played and obtaining, from the devices codes, the key that will allow the decryption of the disc content. That is the Media Key (K_m). , version 78 has been the most recent MKB version. How it works ''Blu-Ray'' or ''HD-DVD'' have as content the encrypted data (usually video), the Volume ID (VID), the Encrypted Title Key(s) and the ''MKB''. The ''MKB'' is also found encrypted in the disc to prevent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Title Keys
A title is one or more words used before or after a person's name, in certain contexts. It may signify either generation, an official position, or a professional or academic qualification. In some languages, titles may be inserted between the first and last name (for example, ''Graf'' in German, Cardinal in Catholic usage (Richard Cardinal Cushing) or clerical titles such as Archbishop). Some titles are hereditary. Types Titles include: * Honorific titles or styles of address, a phrase used to convey respect to the recipient of a communication, or to recognize an attribute such as: ** Imperial, royal and noble ranks ** Academic degree ** Social titles, prevalent among certain sections of society due to historic or other reasons. ** Other accomplishment, as with a title of honor * Title of authority, an identifier that specifies the office or position held by an official Titles in English-speaking areas Common titles * Mr. – Adult man (regardless of marital status) * ...

Device Keys
Device Keys play a role in the cryptographic key management procedure in the Advanced Access Content System (AACS) specification. This specification defines a method for protecting audiovisual entertainment content, including high-definition content. Introduction The AACS’s cryptographic key management procedure uses Device Keys to decrypt one or more elements of a Media Key Block (MKB), in order to extract a secret Media Key (Km). A MKB is located on the physical support (the disc) together with the content of the disc encrypted. MKB enables system renewability. The MKB is generated by ''AACS LA'', and allows all compliant devices, each using their set of secret Device Keys, to calculate the same Media Key (Km). If a set of Device Keys is compromised in a way that threatens the integrity of the system, an updated MKB can be released that causes a device with the compromised set of Device Keys to be unable to calculate the correct Km. In this way, the compromised Device Keys a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volume Unique Key
Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units (such as the cubic metre and litre) or by various imperial units, imperial or United States customary units, US customary units (such as the gallon, quart, cubic inch). The definition of length (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. In ancient times, volume is measured using similar-shaped natural containers and later on, standardized containers. Some simple Three dimensional, three-dimensional shapes can have its volume easily calculated using arithmetic formulas. Volumes of more complicated shapes can be calculated with integral calculus if a formula exists for the shape's boundary. Zero-dimensional space, Zero-, One-dimensional space, one- and tw ...
