Tóm tắt

A conspiracy attack is proposed to show that Wang-Li's scheme is insecure, because anyt or more group members can impersonate othert members to sign any message without holding the responsibility. To avoid the conspiracy attack, this paper presents a new (t, n) threshold signature scheme with traceable signers.
