Gennaro","S. Goldfeder"],"abstract":"A threshold signature scheme enables distributed signing among n players such\r\nthat any subgroup of size t + 1 can sign, whereas any group with t or fewer players cannot.\r\nWhile there exist previous threshold schemes for the ECDSA signature scheme, we present\r\nthe first protocol that supports multiparty signatures for any t ≤ n with efficient, dealerless\r\nkey generation. Our protocol is faster than previous solutions and significantly reduces the\r\ncommunication complexity as well. We prove our scheme secure against malicious adversaries\r\nwith a dishonest majority. We implemented our protocol, demonstrating its efficiency and\r\nsuitability to be deployed in practice.","url_abs":"https://eprint.iacr.org/2019/114.pdf","url_pdf":"https://eprint.iacr.org/2019/114.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"fast-multiparty-threshold-ecdsa-with-fast","repo_url":"https://github.com/ZenGo-X/multi-party-ecdsa","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
