چکیده

Hardware implementations of finite field arithmetic using normal basis are advantageous due to the fact that the squaring operation can be done at almost no cost. In this paper, a new word-parallel bit-serial finite field multiplier using normal basis is presented. The proposed architecture takes w clock cycles to compute the product bits, where the value for w, 1≤w≤ m, can be arbitrarily selected by the designer to set the trade-off between area and speed. It has been shown that the proposed architecture has significantly lower complexity and critical path delay in comparison to the previously proposed architectures.

Efficient implementation of low time complexity and pipelined bit-parallel polynomial basis multiplier over binary finite fields

This paper presents two efficient implementations of fast and pipelined bit-parallel polynomial basis multipliers over GF (2m) by irreducible pentanomials and trinomials. The architecture of the first multiplier is based on a parallel and independent computation of powers of the polynomial variable. In the second structure only even powers of the polynomial variable are used. The par...

Low-Complexity Bit-Parallel Canonical and Normal Basis Multipliers for a Class of Finite Fields

We present a new low-complexity bit-parallel canonical basis multiplier for the field GF(2 m ) generated by an all-onepolynomial. The proposed canonical basis multiplier requires m 2 1 XOR gates and m 2 AND gates. We also extend this canonical basis multiplier to obtain a new bit-parallel normal basis multiplier.

High Performance Elliptic Curve Point Operations

This paper studies the effect of high performance pipelined GF(2 256 ) bit-serial multiplier on elliptic curve point operations. A 3-stage pipelined version of the Massy-Omura GF(2 m ) normal basis multiplier for 160 ≤ m ≤ 256 was studied in terms of area overhead and throughput improvement. Simple gate area and delay models were used to estimate the throughput of the pipelined and the non-pipe...

GF(2^m) Multiplication and Division Over the Dual Basis

In this paper an algorithm for GF(2") multiplication/division is presented and a new, more generalized definition of duality is proposed. From these the bit-serial Berlekamp multiplier is derived and shown to be a specific case of a more general class of multipliers. Furthermore, it is shown that hardware efficient, bit-parallel dual basis multipliers can also be designed. These multipliers hav...

A Low Complexity and a Low Latency Bit Parallel Systolic Multiplier over GF(2m) Using an Optimal Normal Basis of Type II

Using the self duality of an optimal normal basis (ONB) of type II, we present a bit parallel systolic multiplier over GF (2) which has a low hardware complexity and a low latency. We show that our multiplier has a latency m + 1 and the basic cell of our circuit design needs 5 latches (flip-flops). On the other hand, most of other multipliers of the same type have latency 3m and the basic cell ...
