摘要
The paper proposes a forward-secure threshold signature scheme based on RSA which can be applied to network agricultural trade. To realize a single member can sign a message independently, the scheme utilizes a special way to distribute signature key. The analysis shows that security problems such as external attack, collusion attack can be solved with the scheme. Comparing with the present schemes, our scheme is more convenient in key distribution, dynamical in adding and deleting group members.
