Title:
Design and analysis of a distributed ECDSA signing service
Authors: Jens Groth and Victor Shoup
Abstract:We present and analyze a new protocol that provides a distributed ECDSA signing service, with the following properties: it works in an asynchronous communication model; it works with n parties with up to f < n/3 Byzantine corruptions; it provides guaranteed output delivery; it provides a very efficient, non-interactive online signing phase; it supports additive key derivation according to the BIP32 standard. This service is being implemented and integrated into the architecture of the Internet Computer, enabling smart contracts running on the Internet Computer to securely hold and spend Bitcoin and other cryptocurrencies.
