Qiucheng Deng, Xuefei Bai, Guo Li, Yao Wang · 2009
In this paper, a fast hardware implementation of multiplicative inversion in GF(2m) using the optimal normal basis of type II is presented. The approach followed is based on the Sunar-Koc multiplier and the Itoh-Tsujii algorithm. Our design is able to compute multiplicative inversion in GF(2233) using only 26 clock cycles.
