  • Methods and apparatus for multiplication in a galois field GF (2m), encoders and decoders using same
    Patent number: 6343305
    Abstract: Methods and apparatus for multiplication in the Galois field GF(2m) are provided. The methods transform elements of the Galois field into a basis obtained by a permutation of an optimal normal basis. In an embodiment, a multiplier is provided that includes m2 AND gates and 1.5(m2−m) XOR gates. The methods are implemented in hardware such as integrated circuits or in software instructions stored in a computer readable medium such as a hard disk.
