| Abstract: | A broadcast multiple quantum digital signature scheme was proposed,which encrypted messages to be signed by conducting CNOT operation,and used unitary transformation to realize information signature and validation.Analysis shows that,the scheme is not affected by the restrictions of the number of signers,capable of verifiability,high safety and simple technical implementation,and is thus a realizable broadcasting multiple quantum digital signature scheme. |
