Title: A Threshold RSA Signature Scheme without Conspiracy Attack
Abstract: The ordinary threshold signature scheme would be broken if any t or more group members conspire together with each other.Based on RSA and EIGamal signature scheme,a new threshold RSA signature scheme is prompted here.In this scheme,any t members can cooperate to generate a valid group signature on behalf of the group and one verifier is sufficient to verify a given signature with the public keys.Meanwhile,the verifier can not reveal the signatures' identities.However,in exceptional cases such as a legal dispute any group signature can be openedby the trusted center to reveal unambiguously the identities of the actual signers.
