The architecture of this work is modified by the Montgomery modular multiplier and it based on Montgomery powering ladder algorithm. It can work in any length less than 4096-bit. This proposed algorithm provides a shorter latency on modular exponentiation operations than other works. It takes 3.5 ms, 13.7 ms, and 106 ms to complete a 1024-bit, 2048-bit, and 4096-bit key length of RSA calculation time respectively. Furthermore, we modify random number generator based on chaotic map. Testing by SP800-22, this work has higher passing rate than previous work. This embedded in RSA cryptosystem for against SPA and DPA without extra cycle for processing multiplications.
