Tae Ho Kim, Sang Chul Kim, Chang‐Hoon Kim, Chun Pyo Hong · 2008
This paper presents a scalable dual-field Montgomery multiplier based on a new multi-precision carry save adder (MP-CSA), which operates in both types of finite fields GF(p) and GF(2m). We also design a word-level adder for cryptographic applications by reusing the proposed multiplier circuit. The proposed Montgomery multiplier has roughly the same timing complexity and the advantage of reduced chip area requirements compared with the previous result.
