Abstract:-In this paper we propose a low-cost coprocessor architecture for elliptic curves cryptography which supports the main mathematical operations for the computation of ECDSA over GF(2 193 ) , including point doubling, point addition and scalar multiplication over field ECC. As the field is fixed, we use this special property to design special operational units and pipeline structure, only increase 4% area, but at the same time around 40% faster. Our design allows to perform a scalar multiplication over GF(2 193 … Show more
