CRYPTO 2024 WebAbstract. We describe a new Schnorr-based multi-signature scheme (i.e., a protocol which allows a group of signers to produce a short, joint signature on a common message) called $$\mathsf {MuSig}$$, provably secure under the Discrete Logarithm assumption and in the plain public-key model (meaning that signers are only required to have a public key, but …
