... inverse, di- vision and exponentiation. Addition and subtraction are equivalent operations in GF{2'^). Addition in binary finite fields is defined as polynomial addition and can be imple- mented ... of k. A sliding window exponentiation algorithm is typically divided into two phases: exponent partitioning and the field exponentiation computation itself. Addition chains are formally...
