“…There are many methods developed to speed up the performance of the modular multiplication such as Montgomery modular multiplication [12], systolic modular multiplication [7,28,33], high-radix modular multiplication [2,22,25,27,29], parallel calculation of the quotient and the partial result [10], scalable modular multiplication [25][26][27], bipartite technique [34] and Booth recoding technique [3,6,16,26].…”
