The library is simple, consise and straight forward, it also uses a series of look-up tables to increase performance of calculations.<br /><br />The library is broken into three classes, Galois Field, Galois Field Element and Galois Field Polynomial. Operations such as addition, subtraction, multiplication, division, modulus and exponentiation can occur over both field elements and field polynomials and also left and right shifting can occur for field polynomials.<br /><br />The binary extensions of Galois fields (GF(2^m)) are used extensively in digital logic and circuitry. Galois field polynomials within the branch are seen as mathematical equivalents of Linear Feed-Back Shift Register (LFSR) and operations upon elements are accomplished via bitwise operations such as xor, and, or logic. Applications within the fields of cryptography and error correcting codes use Galois fields extensively in such things as S-Box implementations (bit scramblers), strong random number generators and algebraic codes. Galois theory is used to describe and generalize results seen in these fields, for example the AES algorithm can be represented with just a few lines of mathematics using Galois theory and some other related abstract algebra. <br /><br /><br /><br /><b>Project Site</b><br /><a href="http://partow.net/projects/galois/index.html" class="externalLink">http://partow.net/projects/galois/index.html<span class="externalLinkIcon"></span></a><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /></div><div class="ClearBoth"></div>ArashPartowThu, 09 Dec 2010 07:07:39 GMTUpdated Wiki: Home 20101209070739ACreated Release: C++ Galois Field Arithmetic Library (Jan 01, 2000)http://galois.codeplex.com/releases?ReleaseId=56901<div class="wikidoc"><b>Downloads</b><br /><a href="http://www.partow.net/projects/galois/index.html" class="externalLink">http://www.partow.net/projects/galois/index.html<span class="externalLinkIcon"></span></a></div><div class="ClearBoth"></div>ArashPartowSat, 04 Dec 2010 04:31:45 GMTCreated Release: C++ Galois Field Arithmetic Library (Jan 01, 2000) 20101204043145AReleased: C++ Galois Field Arithmetic Library (янв 01, 2000)http://galois.codeplex.com/releases/view/56901
