# Edwards-curve Digital Signature Algorithm (EdDSA) Links: [[Curve25519]], [[Twisted Edwards curve]] ## [[Wikipedia]] https://www.wikiwand.com/en/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.[1] 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.[2] The reference implementation is public domain software.[3]
