Efficient Polynomial Basis Multipliers for Type-II Irreducible Pentanomials

Bit-parallel polynomial basis multipliers over the finite field
GF
(2
^m
) generated using type-II irreducible pentanomials are considered in this brief. The bit-parallel multipliers presented here have the lowest delay known to date for similar multipliers based on this type of irreducible pentanomials, with a very small increase of XOR gates.
