There are two broad approaches: polynomial representation and normal bases, used in software and hardware implementations, respectively. Due to the advantages of normal bases of low complexity, there is also a brief introduction to constructing optimal normal bases. Furthermore, as irreducible polynomials are of fundamental importance for finite fields, the thesis concludes with some irreducibility test.engfinite field multiplicationmodular reductionpolynomial basisnormal basisirreducible polynomialsbakalaureusetööThesis
