Threshold signature is an important aspect of threshold cryptography, and represents almost the core of threshold cryptography research. Based on the threshold signature method, this work was made for resisting conspiracy attack by controlling the group signature issuance rights. The proposed method suffers a flaw for it requires establishing a secretary for signature issuance. By the way, the proposed strategy can be widely applied to various group signature cryptosystems, in which the participant conspirators disable to forge the group signature.
Index Terms:
Threshold signature, threshold cryptography, conspiracy attack, and group signature.
