Abstract:

Proxy blind signature was widely applied to Electronic Voting, Electronic Commerce , and other Network settings. Considering the comprehensive factors of the communication cost, the quantum operation complexity, the verification efficiency, etc., an efficient quantum proxy blind signature scheme based on the correlation of W state is proposed, in which the owner blinds the secret first and then the proxy signer signs the blinded message after authorized. The best advantage of this scheme is that it only needs single-particle measurements in the signature, but not any quantum unitary operation. In addition to, the proposed scheme obtains the higher efficiency in the signature verification and classical communication, compared with the current well-known scheme.
