Implementations of Sunar-Koc multiplier using FPGA platform and WSN node

Abstract

In elliptic curve cryptography (ECC), multiplication operations are used frequently. In order to realize an efficient ECC implementation for large key lengths, it is necessary to choose an algorithm using which it is possible to compute these multiplication operations at higher speeds. This work presents two different implementations of Sunar-Koc multiplier, using FPGA device and a WSN node. This work considered the key lengths 173- bit, 194- bit and 233- bit in both the FPGA and WSN node implementations of the multiplier. A MEMSIC IRIS WSN node has been used during the implementation and a resource comparison, comprising of storage requirements, energy consumption and clock cycles for different key lengths, is made. The obtained FPGA synthesis results have also been compared.
