Efficient quantum multi-proxy signature

Huawang Qin, Wallace K. S. Tang, Raylin Tso


An efficient quantum multi-proxy signature scheme is proposed, in which the original signatory Alice distributes her authority to several proxy signatories, and then each proxy signatory can sign the message for Alice alone. To sign multiple messages, Alice only needs to perform the initializing phase once, and the proxy signatories can use their particles repeatedly. Compared to the existing schemes, our scheme is more efficient in practice.
