In this paper we discuss the security issue of distributed key generation in a distributed threshold protocol. We identify two subtle flaws in the previously proposed discrete-log based distributed key generation protocols. We propose a discrete-log based distributed key generation protocol that meets the necessary security requirements and has no such flaws.
