摘要：
A new forward-secure threshold digital signature scheme which based on multiplicative secret sharing is put forward in this paper. The scheme has the following property: even if more than the threshold numbers of players are compromised, it is not possible to forge signature relating players to the past. This property is achieved while keeping the public key fixed and updating the secret keys at regular intervals. Having been added a refresh protocol, this scheme can tolerate mobile eavesdropping adversaries.
