Quantum Proxy Threshold Multiple Signature Scheme

The security of quantum cryptography is based on microscopic quantum properties, which is much higher than that of classical cryptography. In this paper, we combine the proxy threshold multiple signature with quantum signature in classical cryptography, which not only retains the agent property, threshold property, multiplicity and forward property of the original scheme, but also makes the scheme have the security of quantum signature. So it is a secure and practical signature scheme.
