| | CS 4803 - David Pritchett [AES - Introduction] |
 | | Cast-256 is a symmetric Feistel cipher that is an extension of the Cast-128 algorithm. | | | SAFER+ is an eight to sixteen round, 128-bit block cipher that is based on the existing SAFER family of algorithms. | | | While MAGENTA performs only six to eight rounds, the many S-box substitutions that are required for encryption make it fall among the slowest algorithms. |

| | block cipher: Information From Answers.com |
| | Lucifer is generally considered to be the first civilian block cipher, developed at IBM in the 1970s based on work done by Horst Feistel. | | | An early and highly influential block cipher design was the Data Encryption Standard (DES), developed at IBM and published as a standard in 1977. | | | When encrypting, a block cipher might take a (for example) 128-bit block of plaintext as input, and output a corresponding 128-bit block of ciphertext. |

| | Georgoudis on AES2, Day 2, Rome (FW) |
| | I asked him why government ciphers are still implemented in hardware and not in software working in dedicated one chip computers. | | | I understand that mathematicians prefer to work with well defined problems and consider vague problems as problems not worth thinking about, but ciphers are machines to be used in the real world where the givens are not always clear-cut. | | | Then again it is a trivial matter to have not one but many CPUs computing the same cipher in parallel to account for such type of events. |

| | Feistel cipher |
| | The Skipjack encryption algorithm is an example of such a cipher. | | | Many modern symmetric block ciphers are based on Feistel networks, and the structure and properties of Feistel ciphers have been extensively explored by cryptographers. | | | Like other components of the DES, the iterative nature of the Feistel construction makes implementing the cryptosystem in hardware easier (particularly on the hardware available at the time of DES' design). |

| | The Computer Era |
| | The era of computers and electronics has meant an unprecedented freedom for cipher designers to use elaborate designs which would be far too prone to error if handled by pencil and paper, or far too expensive to implement in the form of an electromechanical cipher machine. | | | But the main thrust of the computer era has been in the development of block ciphers, starting with the LUCIFER project at IBM, which was the direct ancestor of DES, the Data Encryption Standard. | | | The substitution-permutation network was one of the basic concepts behind block ciphers, as it directly implemented Claude Shannon's concepts of confusion and diffusion. |

| | Although block ciphers define how to encrypt a single block of plaintext, generally the algorithms do not discuss what to do about encrypting a sequence of blocks, or encrypting a block of data that is smaller than the algorithm's block size. | | | Symmetric algorithms are the most popular encryption algorithms, mainly because they tend to be fast (essentially all symmetric algorithms shuffle and manipulate the bits in your plaintext and the bits in the key through several similar cycles) and hence are very efficient at encrypting large amounts of data. | | | The best algorithms are secure not because the algorithm used is secret, but because research has shown that the cipher is unbreakable. |

| | However, in some cases these conventions may still not be sufficient to decide how to encode the subkeys; if you wish to use a "-Direct" algorithm where the subkey encoding is not clear, ask for a comment to be added to the algorithm definition. | | | The main significance of this is on tamperproof hardware implementations where the S-boxes were assumed to be secret; for a software implementation, they should be assumed to be public in any case. | | | MDC has nothing to do with the cipher constructions MDC-2 and MDC-4 designed at IBM (which do not have SCAN standard names). |
