As the existing designated-verifier proxy signature schemes can not recover the message,a new designated-verifier proxy multi-signature scheme with message recovery is proposed by using self-certified public key.In the scheme,the proxy signer can generate a valid proxy signature on behalf of original signer groups for designated-verifier,and only the designated-verifier can verify the proxy signature.The signing message is unnecessary to transmit,since the designated-verifier can recover it from the proxy signature.Compared with other designated-verifier proxy signature schemes,the proposed scheme can reduce the communication cost. 消息恢复 指定验证人 代理多重签名 message recovery designated-verifier proxy multi-signature TP309 甘肃省自然科学基金（3ZS051-A25-042）;甘肃省科技攻关项目（2GS064-A52-035-03） 2008-05-01 2021-04-01 5
