Fast threshold ECDSA with honest majority1
Journal of Computer Security, 2022ECDSA 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 ...

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

Compact Zero-Knowledge Proofs for Threshold ECDSA with Trustless Setup
Lecture Notes in Computer Science, 2021Threshold 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-

Dynamic threshold ECDSA signature and application to asset custody in blockchain
Journal of Information Security and Applications, 2021Abstract The centralized exchange is one of the hottest DeFi applications based on blockchain transaction systems. However, depositing user assets to the exchanges brings the security risks of assets misappropriation. Threshold cryptosystem can effectively solve the drawbacks of centralized hosting by assigning the assets authorization to multiple ...

Bandwidth-Efficient Zero-Knowledge Proofs For Threshold ECDSA
The Computer Journal, 2023Abstract In most threshold Elliptic Curve Digital Signature Algorithm (ECDSA) signatures using additively homomorphic encryption, the zero-knowledge (ZK) proofs related to the ciphertext or the message space are the bottleneck in terms of bandwidth as well as computation time.

Secure Two-party Threshold ECDSA from ECDSA Assumptions
2018 IEEE Symposium on Security and Privacy (SP), 2018The Elliptic Curve Digital Signature Algorithm (ECDSA) is one of the most widely used schemes in deployed cryptography. Through its applications in code and binary authentication, web security, and cryptocurrency, it is likely one of the few cryptographic algorithms encountered on a daily basis by the average person.
