摘　　要：随着量子力学和量子算法的不断发展,经典密码学面临着极大的挑战,安全性更高的量子密码学引起了人们的广泛关注,因此提出了一种量子群盲签名方案。该方案将旋转变换矩阵作用在量子叠加态上对信息进行签名,相较于现有的部分量子群盲签名方案提升了量子效率。安全性分析表明,该方案具有不可伪造性和不可否认性,同时可以抵抗签名者之间的合谋攻击。With the continuous development of quantum mechanics and quantum algorithms,classical cryptography is facing severe challenges,and quantum cryptography with higher security attracts wide attention,thus a quantum group blind signature scheme is proposed.This scheme applies the rotation transformation matrix to the quantum superposition state to sign the information,which improves the quantum efficiency compared to the existing partial quantum group blind signature scheme.Security analysis indicates that the proposed scheme satisfies unforgeability and undeniability,while resisting collusion attacks among signers.
