Threshold EdDSA/Schnorr Signatures

Description

Abstract: The EdDSA is the digital signature scheme recently adopted by NIST in FIPS 186-5. This poster considers the challenge of developing a corresponding "threshold scheme", where the signature can be produced even though the private key is distributed across several parties. The scheme is secure even if up to a certain threshold number of parties has been compromised. Important notions and properties include interchangeability and unforgeability.
