Abstract: A multi-verifiers signature scheme using W state is proposed. Based on quantum information splitting, the protocol splits the information into two parts and encrypts them by on-time pads and quantum one-way function. Two verifiers verify the signature. The scheme not only satisfies the security requirements of unforgeability and non-repudiation, but also resists the attack strategies of intercept resend attack and entanglement measure attack. The efficiency and the security are both improved compared with other quantum signature schemes.

摘要： 提出了一种利用W态实现的对经典信息的多人验证签名方案。协议基于量子信息拆分原理，将签名信息拆分成两部分，由一次一密算法和量子单向函数加密签名信息，两个验证人验证签名。方案满足经典安全性要求的不可伪造性和不可否认性，同时也能够抵御量子攻击策略当中的截获重发攻击和纠缠附加粒子攻击，相较其他量子签名方案，效率和安全性都有所提高。
