| Abstract(in English) | Digit serial multiplier for GF(2^m) is an architecture that increases throughput at one cycle by extending multiplicand bits of a bit serial multiplier. In this paper, we propose an MSD(most significant digit) multiplier, which is one of the digit serial multiplier, based on an MSB(most significant bit) multiplier. By connecting D(digit size) pieces of MSB multipliers in series, our implementation is simpler, lower area and less clock-cycles than traditional methods. Implementing elliptic curve cryptosystem (ECC) using the proposal multiplier with ROHM 0.35μm technology, we achieved operation times of 0.115ms for EC scalar multiplication in GF(2^<163>) at 50HMz. |
