| Abstract: | Using Pedersen verifiable threshold secret sharing technique, a (t,n) verifiable threshold signature scheme is constructed based on an improved ECSDA in this paper. The scheme is stable, robust and able to resisting chosen-plaintext attack. The security analysis of this scheme is proposed. |
