Security Enhancement of Digital Signatures for Blockchain using EdDSA Algorithm
Abstract
Blockchain will be the most used technology in the next decade with the key features of distributed ledger and high security. To provide security in the transactions process of hashing, blockchain technology was using the Elliptic Curve Digital Signature Algorithm (ECDSA). Using the ECDSA Algorithm, if any error has happened, this may lead to identify the private key value that which can acquire matching signatures for various documents. To avoid that problem, we suggest using the Edwards-curve Digital Signature Algorithm (EdDSA) Algorithm in generating the hash functions among the transactions, which provides the high-level speed, getting the best performance, and independence in generating the random number. Our suggestion provides improved security while compared to the ECDSA Algorithm.
