An original signer could authorize a group as its proxy signers. Then only t or more of n persons in the proxy group can generate the proxy signature on behalf of the original signer and any t-1 or fewer ones cannot do that. When the proxy signature needs to be verified,any t or more of n persons belonging to the verification group can verify the message and any t-1 or fewer ones cannot verify the validity of the proxy signature. 关 键 词：QUANTUM SIGNATURE THRESHOLD PROXY QUANTUM group SIGNATURE THRESHOLD SHARED verification
