Title: A Threshold RSA Signature Scheme with Traceable Signers
Abstract: This paper proposed a threshold RSA signature with traceable signers. In such scheme, there is a trusted center (TC), which generates all system parameters, the secret keys and the corresponding public keys of the group and all members, and exists a designated clerk, which creates a warrant recording the identities of the signers and other import information. Any t members can collaboratively generate the group signature with the help of the clerk, who verifies the validity of the partial signatures and combines them to the group signature. Any one can verify the correctness of the group signature by the public information and trace out to find the identities of the signers by the warrant.
