A Quantum Proxy Weak Blind Signature Scheme

We present a weak blind signature scheme based on a genuinely entangled six qubits state. Different from classical blind signature schemes and current quantum signature schemes, our quantum weak blind signature scheme could guarantee not only the unconditionally security but also the anonymity of the message owner. To achieve that, quantum key distribution and one-time pad are adopted in our scheme. Our scheme has the characteristics of classical security and quantum security.
