In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called a block, with an unvarying transformation that is specified by a symmetric key.
In modern cryptography, symmetric key ciphers are generally divided into stream ciphers and block ciphers.
In cryptography, the boomerang attack is a method for the cryptanalysis of block ciphers based on differential cryptanalysis.
A broadcast flag is a set of status bits (or a "flag") sent in the data stream of a digital television program that indicates whether or not the data stream can be recorded, or if there are any restrictions on recorded content.
Content Protection for Recordable Media and Pre-Recorded Media (CPRM/CPPM) is a mechanism for controlling the copying, moving and deletion of digital media on a host device, such as a personal computer, or other player.
The Content Scramble System (CSS) is a digital rights management (DRM) and encryption system employed on many commercially produced DVD-Video discs.
The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of electronic data.
Digital rights management (DRM) is a set of access control technologies for restricting the use of proprietary hardware and copyrighted works.
A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device.
DVD-Audio (commonly abbreviated as DVD-A) is a digital format for delivering high-fidelity audio content on a DVD.
DVD-RAM (DVD Random Access Memory) is a disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers.
DVD-Video is a consumer video format used to store digital video on DVD discs, and is the dominant consumer video format in Asia, North America, Europe, and Australia.
The DVD-VR standard defines a logical format for video recording on DVD-R, DVD-RW, and DVD-RAM style media, including the dual layer versions of these media.
In cryptography, a Feistel cipher is a symmetric structure used in the construction of block ciphers, named after the German-born physicist and cryptographer Horst Feistel who did pioneering research while working for IBM (USA); it is also commonly known as a Feistel network.
High-definition television (HDTV) is a television system providing an image resolution that is of substantially higher resolution than that of standard-definition television, either analog or digital.
In cryptography, key size or key length is the number of bits in a key used by a cryptographic algorithm (such as a cipher).
Lars Ramkilde Knudsen (born 21 February 1962) is a Danish researcher in cryptography, particularly interested in the design and analysis of block ciphers, hash functions and message authentication codes (MACs).
The Media Key Block (MKB) is one of the keys included inside the copying protection system (DRM) AACS.
The Portable Document Format (PDF) is a file format developed in the 1990s to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.
Peer review is the evaluation of work by one or more people of similar competence to the producers of the work (peers).
Proprietary software is non-free computer software for which the software's publisher or another person retains intellectual property rights—usually copyright of the source code, but sometimes patent rights.
In cryptography, an S-box (substitution-box) is a basic component of symmetric key algorithms which performs substitution.
Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices.
Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext.
The Technical University of Denmark (Danmarks Tekniske Universitet), often simply referred to as DTU, is a university in Kongens Lyngby, just north of Copenhagen, Denmark.
The Technische Universität Darmstadt (unofficially Technical University of Darmstadt or Darmstadt University of Technology), commonly referred to as TU Darmstadt, is a research university in the city of Darmstadt, Germany.
The 4C Entity (which should be read out as "the four company entity") is a consortium formed by IBM, Intel, Matsushita and Toshiba to establish a common platform for digital rights management schemes.
