FPGA implementation of ECDSA for Blockchain

Abstract

In this paper, we address Field Programmable Gate Array (FPGA) implementation of the Elliptic Curve Digital Signature Algorithm(ECDSA), which is suitable for cryptocurrencies in blockchain. Although the ECDSA requires high computational efforts, utilization of a specific logic circuit allows us quick and easy computation. In this paper, we give implementation results of the ECDSA on an FPGA, and mention the superiority of FPGA implementation by comparing its simulation result with that of software based computation using a CPU.
