Abstract :
Based on a new representation of GF(2n), we present two multipliers for all irreducible trinomials. Space complexities of the multipliers match the best results. The time complexity of one multiplier is TA + (1 + [log2 n])TX for all irreducible trinomials, where TA and TX are the delay of one 2-input AND and XOR gates, respectively.
