Three modular reduction algorithms for large integers are compared with respect to their performance in portable software: the classical algorithm, Barrett’s algorithm and Montgo...
We describe a new method to perform the modular exponentiation operation, i.e., the computation of c = me mod n, where c, m, e and n are large integers. The new method uses the di...
In this paper, an efficient Montgomery multiplier is introduced for the modular exponentiation operation, which is fundamental to numerous public-key cryptosystems. Four aspects a...
