Web29 de ago. de 2024 · Multi-signatures (MS) are a special type of public key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain wallets or to strengthen the security of blockchain consensus protocols are … 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 …

Web15 de set. de 2024 · When concurrent executions are allowed, our algorithm leads to practical attacks against unforgeability of blind signature schemes such as Schnorr and Okamoto–Schnorr blind signatures, threshold signatures such as GJKR and the original version of FROST, multisignatures such as CoSI and the two-round version of MuSig, …
WebExploiting the similarities between FSwA and Schnorr-style signatures, our approach makes the most of observations from recent advancements in the discrete log setting, such as Drijvers et al.’s seminal work on two-round multi-signatures (S&P 2024).

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. 千代紙 折り紙 ダイソーWeb11 de ago. de 2024 · Secure 2-Round Schnorr-Based Multi-signatures: We compare the existing 2-round Schnorr-based Multi-Signatures in Table 1.We note that we do not give the key aggregation operations in Table 1 to obtain the aggregated public key PK because this is necessary step for all multi-signature protocols.
