Abstract :
In this paper, a new forward secure threshold signature scheme is presented, which is the first one from bilinear pairings. Compared with the known schemes against malicious adversary, the new scheme needs the fewest interactions and is very efficient. As an additional contribution, we present a new interactive zero-knowledge proof protocol and convert it into a non-interactive protocol to verify the validity of part signatures in this scheme. The scheme is robust against malicious adversary and forward secure in the random oracle model
