EdDSA
In public-key cryptography, Edwards-curve Digital Signature Algorithm (EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. It is designed to be faster than existing digital signature schemes without sacrificing security. It was developed by a team including Daniel J. Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, and Bo-Yin Yang. The reference implementation is public-domain software.
Ed25519
Ed25519은 EdDSA(Edwards‑curve Digital Signature Algorithm)의 구현체 중 하나로, 보안성과 성능을 고려하여 설계된 타원곡선 디지털 서명 알고리즘이다. Curve25519 계열의 twisted Edwards 곡선을 사용하며, SHA‑512 해시 함수와 결합되어 빠른 서명(sign) 및 검증(verification)을 제공한다.
