Abstract
In this paper, an efficient architecture for the finite field multiplier is proposed. This architecture is faster and smaller than any other LFSR architectures. The traditional LFSR architecture needs t x m registers for achieving the t times speed. But, we designed the multiplier using a novel fast architecture without increasing the number of registers. The proposed multiplier is verified with a VHDL description using SYNOPSYS simulator. The measured results show that the proposed multiplier is 2 times faster than the serial LFSR multiplier. The proposed multiplier is expected to become even more advantageous in the smart card cryptography processors.
