Abstract: The security of a forward-secure threshold signature scheme proposed by MI Jun-li is analyzed. It points out that it can be forged, and not forward. At the end, this paper proposes a new scheme based on ELGamal forward-secure system.

Key words: forward security, threshold signature, forgery attack, collusion attack, new scheme
