| 摘 要： | A multi-proxy quantum group signature scheme with threshold shared verification is proposed. An original signer may authorize a proxy group as his proxy agent. Then only the cooperation of all the signers in the proxy group can generate the proxy signature on behalf of the original signer. In the scheme, any t or more of n receivers can verify the message and any t - 1 or fewer receivers cannot verify the validity of the proxy signature.

| Abstract: | A multi-proxy quantum group signature scheme with threshold sharedverification is proposed. An original signer may authorize a proxygroup as his proxy agent. Then only the cooperation of all thesigners in the proxy group can generate the proxy signature onbehalf of the original signer. In the scheme, any $t$ or more of $n$receivers can verify the message and any $t-1$ or fewer receiverscannot verify the validity of the proxy signature. |
