Ghosh.Efficient hardware implementations of arithmetic operations in the Galois field GF(2^m) are highly desirable for several applications, such as coding theory, computer algebra and cryptography. Among these operations, multiplication is of special interest because it is considered the most important building block. Therefore, high-speed algorithms and hardware architectures for computing multiplication are highly required. In this paper, bit-parallel polynomial basis multipliers over the binary field GF(2^m) generated using type II irreducible pentanomials are considered. The multiplier here presented has the lowest time complexity known to date for similar multipliers based on this type of irreducible pentanomials.engjournal articlehttp://dx.doi.org/10.1109/TCSI.2015.2500419http://ieeexplore.ieee.orgopen access004Bit-parallel multipliersFinite fieldGF(2^m)Irreducible pentanomialsPolynomial basis.Ordenadores1203 Ciencia de Los Ordenadores
