Compact Zero-Knowledge Proofs for Threshold ECDSA With Trustless Setup [PDF]
Lecture Notes in Computer Science, 2021 Threshold ECDSA signatures provide a higher level of security to a crypto wallet since it requires more than t parties out of n parties to sign a transaction. The state-of-the-art bandwidth efficient threshold ECDSA used the additive homomorphic Castagnos and Laguillaumie (CL) encryption based on an unknown order group G, together with a number of zero-

Efficient Threshold-Optimal ECDSA [PDF]
Lecture Notes in Computer Science, 2021 This paper proposes a threshold-optimal ECDSA scheme based on the first threshold signature scheme by Gennaro et al. with efficient non-interactive signing for any $t+1$ signers in the group, provided the total group size is more than twice the threshold

Fast Threshold ECDSA With Honest Majority [PDF]
Lecture Notes in Computer Science, 2020 ECDSA is a widely adopted digital signature standard. A number of threshold protocols for ECDSA have been developed that let a set of parties jointly generate the secret signing key and compute signatures, without ever revealing the signing key. Threshold protocols for ECDSA have seen recent interest, in particular due to the need for additional ...

Low-Bandwidth Threshold ECDSA via Pseudorandom Correlation Generators [PDF]
2022 IEEE Symposium on Security and Privacy (SP), 2022 Digital signature schemes are a fundamental component of secure distributed systems, and the theft of a signing-key might have huge real-world repercussions e.g., in applications such as cryptocurrencies. Threshold signature schemes mitigate this problem by distributing shares of the secret key on several servers and requiring that enough of them ...

Threshold ECDSA From ECDSA Assumptions: The Multiparty Case [PDF]
2019 IEEE Symposium on Security and Privacy (SP), 2019 Cryptocurrency applications have spurred a resurgence of interest in the computation of ECDSA signatures using threshold protocols---that is, protocols in which the signing key is secret-shared among n parties, of which any subset of size t must interact in order to compute a signature. Among the resulting works to date, that of Doerner et al. requires

Three-Round (Robust) Threshold ECDSA From Threshold CL Encryption
Lecture Notes in Computer ScienceThreshold ECDSA has become a crucial security component in blockchain and decentralized systems, as it mitigates the risk of a single point of failure. Following the multiplicative-to-additive approach, the state-of-the-art threshold ECDSA (Doerner et al.

Robust Threshold ECDSA With Online-Friendly Design in Three Rounds [PDF]
2025 IEEE Symposium on Security and Privacy (SP)Threshold signatures, especially ECDSA, enhance key protection by addressing the single-point-of-failure issue. Threshold signing can be divided into offline and online phases, based on whether the message is required. Schemes with low-cost online phases
