On the security of two-round multi-signatures
WebIn this work, we point out serious security issues in all currently known two-round multi-signature schemes (without pairings). First, we prove that none of the schemes can be … 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 …
On the security of two-round multi-signatures
Did you know?
WebA multi-signature scheme allows a group of signers to collaboratively sign a message, creating a single signature that convinces a verifier that every individual signer approved the message. The increased interest in technologies to decentralize trust has triggered the proposal of highly efficient two-round Schnorr-based multi-signature schemes … Web2 de fev. de 2024 · Revisions A preliminary version of this paper, dated January 15, 2024, proposed a 2-round variant of \(\mathsf {MuSig}\), where the initial commitment round is omitted, claiming provable security under the One More Discrete Logarithm (OMDL) assumption [10, 11].However, Drijvers et al. [] have discovered a flaw in the security …
Web18 de mar. de 2024 · Multi-signatures enable a group of signers to produce a single signature on a given message. Recently, Drijvers et al. (S&P'19) showed that all thus far proposed two-round multi-signature schemes in the DL setting (without pairings) are insecure under concurrent sessions, i.e., if a single signer participates in multiple signing … Web16 de ago. de 2024 · Boneh D Drijvers M Neven G Peyrin T Galbraith S Compact multi-signatures for smaller blockchains Advances in Cryptology – ASIACRYPT 2024 2024 Cham Springer 435 464 10.1007/978-3-030-03329-3_15 Google Scholar Digital Library; 11.

WebOur DL-based threshold signatures are the first two-round scheme with security proved based solely on the discrete logarithm assumption in the ROM. The most efficient protocol is FROST [KG20,BCK`22], which is slightly more efficient than our scheme since it generates plain Schnorr signatures; however, FROST relies on the stronger OMDL assumption. sims 4 rave location dj boothWeb2016), and MuSig by Maxwell et al.
