Along with the progress of the information society, we are relying more and more on digital information processing with security. Cryptography plays an important role in a situation where unwanted eavesdropping or falsification has to be avoided. Public key encryptions including RSA require a huge number of arithmetic operations. Major part of its operation is modular multiplication with very large bit-width. This operation takes long time, and there is an advantage in hardware implementation of it. We propose the hardware implementation of N-bit-wise multiplier. It allows the operation performed at the speed 2 times the original performance for the same circuit size, or the circuit size reduced to approximately 60% for the same processing time. Employing the architecture proposed in this paper contributes to the performance improvement of encryption system and the reduction of chip size of encryption system.
