ABSTRACT
<p><b>Abstract</b>—In this paper, a new method for calculation of Zech's logarithm in <tmath>$GF(2^m)$</tmath> is presented. For a given element, the logarithm is calculated by bit operations performed on its binary representation. No look-up tables are used. The proposed method makes feasible the implementation of an universal-type device for finite field arithmetic.</p>
INDEX TERMS
Zech logarithms, finite fields, discrete neural networks.
