  • Published 2003


A Distributed Key Generation (DKG) protocol is an essential component of any threshold cryptosystem. It is used to initialize the cryptosystem and generate its private and public keys, and it is used as a subprotocol, for example to generate a one-time key pair which is a part of any threshold El-Gamal-like signature scheme. Gennaro et al. showed [GJKR99… (More)
