Interest in normal bases over finite fields stems both from mathematical theory and practical applications. There has been a lot of literature dealing with various properties of normal bases (for finite fields and for Galois extension of arbitrary fields). The advantage of using normal bases to represent finite fields was noted by Hensel in 1888. With the introduction of optimal normal bases, large finite fields, that can be used in secure and e#cient implementation of several cryptosystems, have recently been realized in hardware. The present thesis studies various theoretical and practical aspects of normal bases in finite fields. We first give some characterizations of normal bases. Then by using linear algebra, we prove that F q n has a basis over F q such that any element in F q represented in this basis generates a normal basis if and only if some groups of coordinates are not simultaneously zero. We show how to construct an irreducible polynomial of degree 2 n with linearly i...
FPGA Implementation of Point Multiplication on Koblitz Curves using Kleinian Integers

, 2006
"... Abstract. We describe algorithms for point multiplication on Koblitz curves using multiplebase expansions of the form k = ∑ ±τ a (τ − 1) b and k = ∑ ±τ a (τ − 1) b (τ 2 − τ − 1) c. We prove that the number of terms in the second type is sublinear in the bit length of k, which leads to the first p ..."

Abstract. We describe algorithms for point multiplication on Koblitz curves using multiplebase expansions of the form k = ∑ ±τ a (τ − 1) b and k = ∑ ±τ a (τ − 1) b (τ 2 − τ − 1) c. We prove that the number of terms in the second type is sublinear in the bit length of k, which leads to the first provably sublinear point multiplication algorithm on Koblitz curves. For the first type, we conjecture that the number of terms is sublinear and provide numerical evidence demonstrating that the number of terms is significantly less than that of τadic nonadjacent form expansions. We present details of an innovative FPGA implementation of our algorithm and performance data demonstrating the efficiency of our method. 1

Abstract—This paper presents a method for producing hardware designs for elliptic curve cryptography (ECC) systems over the finite field qp@P A, using the optimal normal basis for the representation of numbers. Our field multiplier design is based on a parallel architecture containing multiplebit serial multipliers; by changing the number of such serial multipliers, designers can obtain implementations with different tradeoffs in speed, size and level of security. A design generator has been developed which can automatically produce a customised ECC hardware design that meets userdefined requirements. To facilitate performance characterization, we have developed a parametric model for estimating the number of cycles for our generic ECC architecture. The resulting hardware implementations are among the fastest reported: for a key size of 270 bits, a point multiplication in a Xilinx XC2V6000 FPGA at 35 MHz can run over 1000 times faster

This paper examines the implementation of Finite Field arithmetic, i.e. multiplication, division, and exponentiation, for any standard basis GF(2 ) with m8 on a DSP datapath. We introduce an opportunity to exploit cells and the interconnection structure of a typical binary multiplier unit for the Finite Field operations by adding just a small overhead of logic. We develop division and exponentiation based on multiplication on the algorithm level and present a simple scheme for implementation of all operations on a processor datapath.
