Comparative Analysis of Schnorr Digital Signature and ECDSA for Efficiency using Private Ethereum Network

초록

This paper reports the use of the Schnorr Digital Signature as a new alternative instead of the Elliptic Curve Digital Signature Algorithm (ECDSA) currently used in Ethereum. Elliptic curve cryptography, which is the cryptographic background of blockchain digital signature, is explained in the background and related works. This study then examined, the problems facing ECDSA and how the Schnorr Digital Signature could solve them. The test was performed by comparing Schnorr and ECDSA implemented in a private Ethereum network environment. The performance results showed that Schnorr Digital Signature has strengths in terms of efficiency over ECDSA. The efficiency deals with the gas price, signature size, block size, block elapsed time, and signature algorithm calculation time. © 2022 Institute of Electronics and Information Engineers.
