1 \section{EdDSA Signatures}\label{eddsa} 2 With signatures, authenticity and non-repudiation want to be achieved. In this 3 context hashes and public key cryptography are used.\cite{hash2012} For this 4 purpose the Donau uses EdDSA signatures. The Edwards-curve Digital Signature 5 Algorithm or for short EdDSA is a scheme for digital signatures based on the 6 twisted Edwards elliptic curves and the Schnorr signature scheme. EdDSA 7 signatures using the curve Curve25519 are also called Ed25519. The Donau only 8 uses Ed25519. Whether Curve25519 or the Edwards-curve, the scheme is very 9 efficient and secure.\cite{BernsteinEd25519} 10
