WebMay 14, 2024 · Introduction. EdDSA is a Schnorr-based digital signature scheme that functions over elliptic curves. While ECDSA is probably the most widely deployed elliptic curve digital signature scheme, EdDSA has a number of properties that make it an attractive alternative to ECDSA. In this tech note we aim to answer the question "what is EdDSA and … WebJun 29, 2024 · EdDSA also uses a different verification equation (pointed out in the link above) that AFAICS is a little easier to check. Standardized ECDSA does require random per message and fails catastrophically if it repeats for different messages (2); rfc6979 by our very own bear proposes a fix for this but has not been widely adopted, at least not yet.

WebOct 8, 2024 · EdDSA's algorithm allows it to use curves that are more secure while being fast (ECDSA could be done using the complete point addition formulas over ANY elliptic curve, but it would be slower for many curves). Additionally EdDSA is deterministic: there's no need to generate a nonce, and no need to track that a nonce is only used once.
