Abstract
In this paper, a new High-Radix Finite Field multiplication algorithm for GF(2(m)) is proposed for the first time. The proposed multiplication algorithm can operate in a Digit-serial fashion, and hence can give a trade-off between the speed, the area, the input/output pin limitation, and the low power consumption by simply varying the digit size. A detailed example of a new Radix-16 GF(2(m)) Digit-Serial multiplication architecture adopting the proposed algorithm illustrates a speed improvement of 75% when compared to conventional Radix-2 bit-serial realization. This is made more significant when it is noted that the speed improvement of 75% was achieved at the expense of only 2.3 times increase in the hardware requirements of the proposed architecture.
