Abstract

It has become increasingly common to implement discrete-algorithm based public-key protocols on elliptic curves over finite fields. The operations, especially multiplication, over finite fields affect greatly the speed of encryption/decryption. For this reason the contribution describes a fast multiplier for Elliptic Curve Cryptosystems over finite fields GF ((2m1)m2). This multiplier adopts mixed parallel-serial approaches., The number of clock cycles for one field multiplication can be reduced from former m= m2m1 to current m2 with less increase of hardware scales.
