摘要
Abstract
In this paper,a new method of using type Ⅱ normal basis for multiplication is proposed.By an efficient linear transformation,the regular basis of GF(2m)is transformed into m-term polynomials over GF(2m).This polynomial can be multi-plied using any polynomial multiplication algorithm and then converted back to a normal basis using the inverse of the transformation described above.The XOR/AND operations required for this scheme are M(m)+2mlog2(m 2),where M(m)depends on the poly-nomial multiplication algorithm chosen.Compared with other normal basis methods,it has smaller resource consumption.The FPGA comprehensive practice shows that this scheme can significantly reduce the number of LUTs.关键词
