Web13 de abr. de 2024 · The approaches taken in our two-round protocols are highly inspired by \(\mathsf {mBCJ}\) discrete log-based multi-signature by Drijvers et al. In particular, we observe that it is crucial for two-round protocols to use message-dependent commitment keys (as in \(\mathsf {mBCJ}\)) instead of a single fixed key for all signing attempts (as in … WebSecure 2-round Schnorr-based Multi-Signatures: We compare the existing 2-round Schnorr-based Multi-Signatures in Table 1.

WebThis work presents the first provably secure forward-secure multi-signature scheme by deriving a forwardsecure signature scheme from the hierarchical identity-based … 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. highest rated tennis shoes for men
