| Abstract: | Threshold signature is a kind of special and important digital signature. But in the existing threshold signature scheme, conspiracy attack is still a problem which is difficult to solve. This paper analyzes a threshold signature scheme to withstand conspiracy attack, analyzes its weakness and proposes some heuristic idea and methods to withstand conspiracy attack based on the existing threshold signature schemes. |
