Equally spaced polynomials, dual bases, and multiplication in F(2/sup n/)
Dieter Gollmann · IEEE Transactions on Computers · 2002
A proposed multiplier for finite fields given by equally spaced polynomials is based on the transformation from the polynomial basis to its dual basis, combined with multiplication by a constant. We classify the constants that are optimal regarding the cost of this operation and investigate the cost of the inverse transformation.
