Block cipher modes of operation — This article is about cryptography. For method of operating , see modus operandi. In cryptography, modes of operation is the procedure of enabling the repeated and secure use of a block cipher under a single key.[1][2] A block cipher by itself… … Wikipedia
Block cipher — In cryptography, a block cipher is a symmetric key cipher operating on fixed length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take (for example) a 128 bit block of plaintext as… … Wikipedia
Residual block termination — In cryptography, residual block termination is a variation of cipher block chaining mode (CBC) that does not require any padding. It does this by effectively changing to cipher feedback mode for one block. The cost is the increased… … Wikipedia
Pirate decryption — most often refers to the reception of compromised pay TV or pay radio signals without authorization from the original broadcaster. The term pirate in this case is used in the sense of copyright infringement and has little or nothing to do with… … Wikipedia
Media Key Block — The Media Key Block (MKB) is one of the keys that are included inside the copying protection system (DRM) AACS. This system is used to protect Blu ray and HD DVD formats from being copied. The system has been developed by big companies from the… … Wikipedia
Ciphertext stealing — In cryptography, ciphertext stealing (CTS) is a general method of using a block cipher mode of operation that allows for processing of messages that are not evenly divisible into blocks without resulting in any expansion of the ciphertext, at the … Wikipedia

Feistel cipher — In cryptography, a Feistel cipher is a symmetric structure used in the construction of block ciphers, named after the German IBM cryptographer Horst Feistel; it is also commonly known as a Feistel network. A large proportion of block ciphers use… … Wikipedia
