摘　　要：To enhance the robustness of a proxy multi-signature scheme and improve its efficiency, a novel proxy signature paradigm is proposed referred to as In this paradigm, multiple proxy signer candidates identity-based proxy multi-signature （IBPMS）. are employed to play a role of the single proxy signer in the existing model. A provably secure IBPMS scheme is presented which requires only one round broadcast operation. Performance analysis demonstrates that the new scheme outperforms the existing multi-signature schemes in robustness and communication. These properties are rendered to our IBPMS scheme as a more practical solution to secure e-transaction delegation applications of proxy signatures.To enhance the robustness of a proxy multi-signature scheme and improve its efficiency,a novel proxy signature paradigm is proposed referred to as identity-based proxy multi-signature(IBPMS).In this paradigm,multiple proxy signer candidates are employed to play a role of the single proxy signer in the existing model.A provably secure IBPMS scheme is presented which requires only one round broadcast operation.Performance analysis demonstrates that the new scheme outperforms the existing multi-signature schemes in robustness and communication.These properties are rendered to our IBPMS scheme as a more practical solution to secure e-transaction delegation applications of proxy signatures.
