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.
