Design criteria. The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability. The Rijndael S-box can be replaced in the Rijndael cipher ...
UTF-8 is a variable-length character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit.[1] UTF-8 is capable of encoding all 1,112,064[a] valid Unicode code points using one to four one-byte (8-bit) code units. Code points with lower numerical ...

Western Latin character sets (computing) Several 8-bit character sets (encodings) were designed for binary representation of common Western European languages ( Italian, Spanish, Portuguese, French, German, Dutch, English, Danish, Swedish, Norwegian, and Icelandic ), which use the Latin alphabet, a few additional letters and ones with ...

History and structure The PGP Word List was designed in 1995 by Patrick Juola, a computational linguist, and Philip Zimmermann, creator of PGP. The words were carefully chosen for their phonetic distinctiveness, using genetic algorithms to select lists of words that had optimum separations in phoneme space. space.
Description It uses three output levels: + (positive pulse), 0 (no pulse), and − (negative pulse). This means we have 2 4 = 16 input combinations to represent, using 3 3 = 27 output combinations. 000 is not used to avoid long periods without a transition. 4B3T uses a paired disparity code to achieve an overall zero DC bias: six triplets are used which have no DC component (0+−, 0−+, +0 ...
