Quantum blind signature protocol for preventing eavesdropping of signer

The invention discloses a quantum blind signature protocol for preventing eavesdropping of a signer. The protocol is a quantum blind signature scheme for preventing eavesdropping of the signer based on quantum superposition and decoy photons. In the protocol, a message sender blinds a message by using a quantum superposition state, a hash function and decoy photons, and a signer cannot directly know the content of the message, and the eavesdropping behavior can be discovered by a message sender in a mode of measuring the decoy photons. Furthermore, the protocol also comprises that after Bob publishes an original message m and a signature sign (m), the effectiveness of the message and the signature is verified by a third-party message receiver Charlie, QKD and bit-by-bit operation are not needed, the finally published message and signature exist in classic information, multiple times of verification can be carried out, and the efficiency is improved. 本发明公开了一种防签名者窃听的量子盲签名协议，该协议是基于量子叠加和诱骗光子的防签名者窃听的量子盲签名方案。在该协议中，
